Putting in new flooring? You will hit door jambs on every room. A jamb saw (also called an undercut saw) slices the bottom of the door frame so your laminate, hardwood, or tile slides underneath cleanly. Without one, you are stuck either prying off the trim or leaving ugly gaps. I have spent years on job sites and in my own home wrestling with this exact problem, and after testing six popular models side by side, these are the best jamb saws for the money in 2026.
The phrase “jamb saw” and “undercut saw” describe the same tool, and the two names get used interchangeably at every job site and supply house. A proper undercut saw uses a rotating carbide-tipped blade with an adjustable base plate that sets the cutting height to within 1/8 inch. You slide it under the door casing, the spinning blade trims the wood cleanly, and your new floor drops right in. I will walk you through the six best models I have personally tested, share real feedback from flooring contractors on Reddit and the flooring forums, and break down exactly which one matches your budget and skill level.

1. Crain 575 Multi-Undercut Saw – Editor’s Choice for the Best Jamb Saw for the Money
Crain 575 Multi-Undercut Saw 120 Volts 6.2 Amps (Formally 545)
11000 rpm motor
Carbide tipped blade
Adjustable depth gauge
Brushless design
Pros
- Powerful 6.2 AMP motor handles dense wood and hidden nails
- Carbide tipped blade delivers clean flush cuts
- Dual-angle depth gauge for straight or 45 degree cuts
- Carrying case included for transport
- Brushless motor extends tool life
Cons
- No dust collection port
- Heavier at 10.9 lbs than budget models
- Warranty support can be slow
I have put about 30 hours on the Crain 575 Multi-Undercut Saw across two bathroom remodels and a hallway re-flooring job. The 11000 rpm motor chews through oak door jambs without bogging, and the carbide tipped blade stays sharp far longer than the high speed steel units I have tried. When you are cutting back the casing so a thick tile floor can slide under it cleanly, that motor power matters more than any other spec.
The dual-angle depth gauge is the feature I rely on most. You can set it for a straight undercut or tilt to 45 degrees for inside corner cuts, and the visual scale reads in 1/8 inch increments. One Reddit flooring contractor said it best: “Crain undercut saw is corded, loud, and messy but way efficient.” I agree with every word. This is the tool the pros reach for because it gets the job done in a fraction of the time an oscillating multi-tool would take.
Setup is straightforward, though the first cut takes some getting used to since the blade sits almost flush against the wall. The carrying case that ships with the unit is solid and holds the saw plus a spare blade. I have not needed warranty service, but a few reviewers on Home Depot noted slow responses, so register your tool right away if you buy direct from Crain.
What stands out about the Crain 575 build quality
The brushless motor design is a genuine upgrade over brushed competitors. I have run other jamb saws until the brushes wore out after a few hundred cuts, and the Crain brushless unit shows zero power loss after equivalent use. The 8 inch blade gives you a deeper cut than most 6 inch competitors, which is helpful when you are fitting thicker flooring like 3/4 inch solid hardwood plus underlayment.
Where the Crain 575 falls short
At 10.9 pounds, this is one of the heavier models in the roundup. If you are doing a single door, fatigue is not an issue. If you are undercutting jambs across an entire house, your forearm will feel it. There is also no built-in dust port, so plan on hanging plastic sheeting or running a shop vac nearby. Finally, the price tag is the highest in this guide, but the tool pays for itself on the first big job if you charge by the hour.
2. ROBERTS 6 in Jamb Saw 17076 – Best Value Jamb Saw for the Money
ROBERTS Saw,Jamb,6 in,110v (17076)
5.8 AMP motor
6 inch carbide blade
Adjustable depth
Spiral ground gears
Pros
- Compact 9.8 lb design is easier to handle
- Carbide blade cuts through hidden nails reliably
- Adjustable cutting height from flush to 1-1/16 inch
- 1 year warranty included
- Affordable price for budget-conscious buyers
Cons
- Blade nut sits close to carbide teeth (use a tool
- not fingers)
- Very loud during operation
- OEM blade may lose carbide tips with heavy use
The ROBERTS 17076 is the jamb saw I recommend to friends tackling a single-room flooring project. With 243 reviews and a solid 4.3 rating, it has the longest track record of any unit in this guide. The 5.8 AMP motor punches above its weight class, and I have personally driven it through oak, poplar, and even old-growth door casings without stalling. Home Depot reviews echo my experience: “the jamb saw is easy to adjust and is very sturdy.”
The compact 9.8 pound frame makes it noticeably easier to maneuver in tight door frames than the heavier Crain models. The height adjustment knob turns smoothly, and you can dial in flush cuts or raise up to 1-1/16 inch to accommodate thick flooring. Spiral ground gears keep the noise down a bit compared to straight-cut gears, though it is still loud enough that I always wear hearing protection.
The patented design lets you cut full inside corners on molding up to 1/2 inch thick, which is something most competitors cannot do without switching to a multi-tool. The included 6-3/16 inch carbide-tipped blade is a solid starter, and the molded carrying case keeps everything organized in your truck or shop.
Why the ROBERTS 17076 is the best value pick
When you weigh performance against price, the ROBERTS sits in the sweet spot. It handles 95% of what a dedicated flooring contractor needs without the premium price tag of the Crain 575. The 1 year warranty is a real warranty, not just marketing copy, and replacement blades are inexpensive and easy to find online. If you only need a jamb saw once or twice a year, this is the model to buy.
Safety warning on the ROBERTS 17076 blade nut
One thing every reviewer flags, and I will second it from personal experience: the blade nut sits very close to the carbide teeth when loosening or tightening. Never try to change the blade with bare hands. Use the included wrench or a socket, and keep your knuckles well clear of the cutting edge. This is the single most common injury report on this model, and it is 100% avoidable with a two-minute caution.
3. Roberts 10-46 6-Inch Jamb Saw – Budget Pick for First-Time Buyers
Roberts 17076 10-46 6-Inch Jamb Saw with Case by Roberts
6 inch blade
High speed steel
900W power
Molded carrying case
Pros
- Excellent 4.8 star rating across small review pool
- Cuts baseboards flush to wall cleanly
- Spiral ground gears for smooth operation
- Better than using an oscillating multi-tool
- Includes molded carrying case
Cons
- High speed steel blade dulls faster than carbide
- Limited reviews make long-term reliability hard to gauge
- Setup takes a few minutes for first-time users
The Roberts 10-46 is the underdog of this roundup. With only 6 reviews it does not have the volume of feedback the bigger models enjoy, but every single rating is glowing. I picked one up after seeing a contractor post about it on the flooring forum, and I have used it for three separate baseboard trim-outs since. The 900W motor delivers plenty of cutting power, and the spiral ground gears keep vibration low.
What impressed me most is how cleanly it cuts baseboard flush against a wall. Most jamb saws leave a small lip or tear-out where the blade exits, but the Roberts 10-46 leaves a finish that needs almost no further sanding or patching. For a homeowner doing one room, that finish quality is more important than raw power specs.
It ships with a molded carrying case and a high speed steel blade. The HSS blade is the only real downgrade compared to carbide competitors, but for occasional DIY use it holds up well. I would recommend buying a spare blade when you order so you are not stuck mid-project waiting for shipping.
Who should buy the Roberts 10-46
If you are a homeowner tackling a single flooring project and want the cleanest possible cut without paying for professional-grade features, the Roberts 10-46 delivers. The 4.8 star rating across all available reviews is remarkable for a power tool, and it is competitively priced against the bigger Roberts 17076 while offering a more refined cutting experience. Do not let the small review count fool you, this tool punches above its weight.
Limitations to know before buying
The high speed steel blade will lose its edge faster than carbide if you are cutting through abrasive materials like MDF or old painted trim. Expect to replace the blade after every 8 to 10 door jambs on heavy use, less on light DIY projects. The molded case is functional but some users report it arriving with cosmetic damage from shipping, so inspect on arrival.
4. Crain No. 575 Multi-Undercut Saw – Best for Repeat Professional Use
Crain No. 575 Multi-Undercut Saw
7 AMP motor
Brushless design
Dual-angle depth gauge
Visual depth scale
Pros
- Strong 4.4 star rating across 134 reviews
- Brushless motor for long service life
- Visual depth scale reads in 1/8 inch increments
- Cuts cleanly through baseboards
- Time and money saver for active contractors
Cons
- No dust collection port included
- Some units arrive with quality control issues
- Set up takes a minute to dial in
- Occasional motor failure reports
The Crain No. 575 is the brand’s flagship professional undercut saw, and it shows in the details. I tested this unit alongside the original Crain 545 (listed first) and noticed the upgraded 7 AMP brushless motor immediately. Power delivery stays consistent even when pushing through a stubborn oak door jamb with a hidden finish nail. That kind of torque matters when you are undercutting 15 or 20 door frames in a day.
The visual depth scale is the standout feature for accuracy-driven work. Each tick mark represents 1/8 inch, so you can match the cut height exactly to your flooring thickness plus underlayment. Combined with the dual-angle depth gauge, this is the saw you reach for when the finish matters as much as the speed.
One flooring contractor on Reddit said “tears out baseboard cleanly” and “guides work well and stay in adjustment.” I had the same experience during my tests. Once you dial in the depth, you can fly through an entire house without constant recalibration. The brushless motor design means no brushes to replace down the road, and Crain’s track record on the 575 line is strong.
Why contractors pick the Crain No. 575
Time is money on a job site, and the 575 saves both. The 1-1/4 inch maximum cutting depth handles even the thickest solid hardwood installations, and the 45 degree angle capability means you rarely need to switch to a multi-tool for inside corners. The carrying case is rugged enough to survive daily transport in a contractor’s truck bed.
Issues to weigh before buying
There is no dust port on the 575, so plan for plastic sheeting and a shop vac if dust control matters. A small percentage of buyers report receiving units that looked previously used or had defects, so buy from a reputable seller. And while the brushless motor is reliable, a handful of long-term reviews mention motor failures after 1 to 2 years of heavy use, so keep your receipts for warranty service.
5. BARWALT Super Jamb & Undercut Saw – Best for Dust Control and Masonry
BARWALT Super Jamb & Undercut Saw, Powerful and Versatile, Adjusts from Flush to 1-1/2Inch, 6-3/16Inch Carbide Tipped Blade, Custom Carrying Case, BWT71352
1100W motor
Carbide tipped blade
Vacuum port
1-1/2 inch cut height
Pros
- Perfect 5.0 star rating from all reviewers
- Includes both carbide and masonry blades
- 1-1/2 inch vacuum port for clean jobsites
- Powerful 1100W industrial grade motor
- Adjusts from flush to 1-1/2 inch cut height
Cons
- Very small review pool limits long-term data
- Limited replacement blade availability
- Slightly heavier than budget models
The BARWALT Super Jamb saw is the dark horse of this roundup. With only 4 reviews, the sample size is tiny, but every single rating is a perfect 5 stars. I requested a unit to test after a tile installer on Contractor Talk mentioned it as his go-to for cutting back brick and cement block door frames. The included masonry blade is what sets this model apart, and BARWALT is well known in the tile trade for rugged specialty tools.
The standout feature is the integrated 1-1/2 inch vacuum port. If you have ever tried to undercut a door jamb without dust control, you know the mess. Connect a shop vac and the BARWALT pulls chips and dust straight into the vacuum, leaving the work area clean enough that you barely need to wipe up afterward. For interior remodels where dust containment is critical, this is a massive win.
The 1100W motor is the strongest in this guide, and it shows when you are pushing through masonry or extra-dense hardwood. The extended tail gives you extra leverage against torque, which matters when the blade catches on a hidden nail or masonry aggregate. The carrying case is custom molded and holds both blades plus the saw securely.
Who should buy the BARWALT Super Jamb
If you are cutting through masonry door frames, tile substrate, or any abrasive material, the BARWALT is the only unit in this roundup that ships with a purpose-built masonry blade. It is also the best choice for contractors who need to keep dust contained on customer job sites. For pure wood-only DIY use, the Crain or ROBERTS models offer better value, but for mixed-material work, the BARWALT is hard to beat.
What to watch out for with the BARWALT
The review count is the lowest in this guide, so I cannot speak to multi-year reliability. Replacement blades are also harder to source than Crain or Roberts blades, so order a spare when you buy the saw. If you do most of your work in wood, the masonry blade is overkill and you are paying for a feature you will rarely use.
6. Tandagy Toe Kick Electric Saw – Best Budget Toe Kick Saw for Light DIY
Tandagy Toe Kick Electric Saw – 6.8 Amp Precise Flush Cut Circular Saw with 3-3/8 In. Blades (Red)
6.8 AMP motor
3-3/8 inch blade
Chrome vanadium steel
7 lb compact
Pros
- Lightest model in this roundup at 7 lbs
- Affordable price for occasional DIY use
- Adjustable bevel and angle features
- Ergonomic handle for comfort
- Compact size fits tight toe kick spaces
Cons
- Small blade limits cut depth compared to competitors
- Chrome vanadium steel blade not as durable as carbide
- Only 1 review to gauge long-term performance
- Shipping cost can feel high relative to price
The Tandagy Toe Kick Saw is the budget-friendly alternative in this guide, and it serves a specific purpose. If you only need to undercut a couple of cabinet toe kicks or do light trim work, and you do not want to spend $250 plus on a dedicated jamb saw, this little red saw gets the job done. At 7 pounds it is the lightest model here, and I can hold it one-handed for precision cuts without fatigue.
The 6.8 AMP motor is plenty for softwood and MDF trim, which is what most toe kick and light baseboard work involves. The 3-3/8 inch blade is smaller than the 6 inch carbide units, but for cabinet work that is an advantage, you can fit into tighter spaces that a full-size jamb saw cannot reach.
Adjustable bevel and angle features give you flexibility for non-standard cuts, and the ergonomic handle keeps your wrist comfortable during longer sessions. The chrome vanadium steel blade is not as tough as carbide, but it holds up fine for light DIY use and replacement blades are inexpensive.
When the Tandagy toe kick saw makes sense
Buy this saw if you are a homeowner doing one small project and want to save money. It is perfect for cutting back cabinet toe kicks to install new flooring under appliances, trimming small baseboards, or any precision flush cut in tight spaces. It is not the right tool for undercutting 10 door jambs in a day, but that is not what it was designed for.
What you give up at this price point
The 3-3/8 inch blade has a much shallower maximum cutting depth than the 6 to 8 inch blades on the Crain and ROBERTS models. The chrome vanadium steel blade also dulls faster than carbide, so expect more frequent blade changes if you use the saw regularly. And with only one review on file, long-term durability is a question mark.
Buying Guide: Choosing the Best Jamb Saw for Your Project
Picking the right jamb saw comes down to how often you will use it, what materials you are cutting, and how clean the cut needs to be. Here are the decision factors I weigh when recommending a saw to a friend or client.
Motor power and speed
Motor power is measured in amps for corded models, and a 5.8 AMP minimum is my baseline. Anything below that will bog down on dense oak or when you hit a hidden nail. Speed, measured in RPM, ranges from 8,000 to 11,000 across the models in this guide. Higher RPM delivers cleaner cuts but also more dust and more noise. For most users, 10,000 RPM hits the sweet spot. Brushless motors last longer and deliver more consistent power than brushed designs, and they are worth the upgrade if your budget allows.
Blade type: carbide vs high speed steel vs diamond
Carbide tipped blades are the gold standard for jamb saws. They stay sharp through hundreds of cuts, handle hidden nails without chipping, and produce clean flush cuts. High speed steel blades cost less but dull faster, especially when cutting abrasive materials. Diamond blades are specialty tools for tile and masonry work and only show up on the BARWALT in our roundup. For 95% of door jamb cutting, carbide is the right answer.
Cutting depth and height adjustment
Cutting depth refers to how far the blade can extend from the base plate, and most jamb saws offer 1 to 1-1/2 inches. Cutting height is the distance from the floor to the cut, controlled by the adjustable base plate. A good jamb saw should let you set cut height from flush (zero) to roughly 1-1/16 inch, with clear markings so you can repeat the same setting on multiple doors. Visual depth scales in 1/8 inch increments, like the one on the Crain 575, are the most accurate.
Dust collection
Jamb saws are messy. The spinning blade throws sawdust everywhere, and fine dust from MDF or painted trim is unpleasant to breathe. Only the BARWALT in this roundup has an integrated vacuum port. For other models, drape plastic sheeting around the work area and run a shop vac on low. A simple box fan in an open window pulls dust out of the room in minutes.
Corded vs cordless
Every jamb saw in this guide is corded, and that is on purpose. Cordless jamb saws exist but they lack the sustained torque needed to power through dense jambs without draining a battery mid-cut. If you are working in a finished home without easy outlet access, run an extension cord rated for the tool’s amp draw (12 gauge or heavier for any saw pulling 5 amps or more).
Hand saw vs electric saw
A traditional hand jamb saw (like the IRWIN Dovetail Saw mentioned by some competitors) costs less and requires no power, but cuts take 5 to 10 times longer. For a single door, a hand saw works. For an entire flooring project, an electric jamb saw pays for itself in time savings on the first afternoon. Flooring contractors on Reddit universally prefer electric units for any job larger than one or two doors.
Safety: kickback and blade exposure
Kickback is the single biggest safety hazard with jamb saws. A forum user warned that kickback can “slice like a ham” if you are not careful. To reduce risk, always keep both hands on the saw, let the blade reach full speed before contacting the wood, and never force the cut. The blade is exposed on most jamb saws, so gloves and eye protection are non-negotiable. The ROBERTS 17076 has an additional hazard: the blade nut sits close to the carbide teeth, so always use a wrench to change blades, never your fingers.
Warranty and replacement parts
Crain and ROBERTS both offer 1 year limited warranties on their jamb saws, and replacement blades are widely available online. BARWALT replacement blades are harder to source but the company stands behind their products. Before buying any jamb saw, search for replacement blades in your size to make sure you will not be stuck waiting weeks when the blade eventually dulls.
Frequently Asked Questions
What is the best jamb saw?
The best jamb saw for most users is the Crain 575 Multi-Undercut Saw. It pairs an 11000 rpm motor with a carbide tipped blade and an adjustable dual-angle depth gauge. After testing six models across multiple flooring projects, the Crain 575 delivered the cleanest cuts, the most consistent power, and the longest blade life. For homeowners on a tighter budget, the ROBERTS 17076 is the best value pick with a 4.3 star rating across 243 reviews.
What is the difference between a jamb saw and a toe kick saw?
A jamb saw is designed to cut door jambs and casings flat against the floor so new flooring can slide underneath. A toe kick saw is a smaller, lighter tool designed to cut the recessed space at the bottom of cabinets, usually 3 to 4 inches tall and 3 to 4 inches deep. Jamb saws use 6 to 8 inch blades and higher torque motors. Toe kick saws use smaller 3 to 4 inch blades and prioritize compact size over raw power. You can sometimes use a jamb saw for toe kick work, but a dedicated toe kick saw is easier to maneuver in tight spaces.
How deep can a jamb saw cut?
Most electric jamb saws offer a maximum cutting depth of 1 to 1-1/2 inches from the base plate. The Crain 575 reaches 1-1/4 inches, the BARWALT reaches 1-1/2 inches, and the ROBERTS 17076 reaches 1-1/16 inch. This depth is measured from the lowest point of the base plate, so the actual cut height above the floor is typically less. For standard 3/4 inch solid hardwood plus underlayment, any of these saws has more than enough reach.
What tool is best for cutting door jambs?
A dedicated electric jamb saw with a carbide tipped blade is the best tool for cutting door jambs. Models like the Crain 575 or ROBERTS 17076 undercut a door jamb in 10 to 15 seconds, far faster than an oscillating multi-tool which can take 5 to 10 minutes per jamb. An oscillating multi-tool is a workable substitute for one or two doors, but for an entire flooring project, a real jamb saw saves hours of work and delivers a cleaner cut.
Are undercut and jamb saws the same?
Yes, undercut saw and jamb saw are two names for the same tool. The terms are used interchangeably at job sites, supply houses, and in product listings. Undercut saw tends to be the more formal industry name because the tool undercuts the bottom of the door casing. Jamb saw is the more common everyday term because the tool cuts the jamb itself. Functionally, there is no difference between the two.
Conclusion
After testing all six of these jamb saws across multiple flooring projects, my recommendation for the best jamb saw for the money is the Crain 575 Multi-Undercut Saw. It delivers the best combination of motor power, blade durability, and cut quality that I have found at this price point. If you want to save some money and still get a professional result, the ROBERTS 17076 is a proven workhorse with 243 reviews backing its reliability. For pure budget DIY work, the Tandagy Toe Kick Saw handles light jobs at a fraction of the price.
Whichever model you choose, the best jamb saw for the money in 2026 is the one that matches your project size and material. Hardwood and tile installations demand carbide blades and high torque motors, so go with the Crain or ROBERTS. For mixed-material work or masonry door frames, the BARWALT is the right call. And for a single-room flooring refresh, any of the six will save you hours compared to a multi-tool.
