What Sawzall Blade Cuts Concrete, and Do Masonry Blades Exist?
Yes. Reciprocating saw blades made for masonry exist, and they come in two main types: carbide-tipped blades and diamond grit blades. Both can cut concrete, brick, block and similar materials, but they work by grinding rather than slicing, so they are best for short, shallow or awkward cuts instead of deep, clean cuts through thick slabs.

A standard wood or metal Sawzall blade will not cut concrete. Its teeth dull or snap almost immediately. You need a blade built for masonry, and those fall into two groups.
Carbide-tipped masonry blades have a few hardened teeth that chip and crush material as the blade moves back and forth. Diamond grit blades have no real teeth. Instead, industrial diamond particles are bonded to the edge, and they abrade the material away. Both are sold in reciprocating saw fittings, so they fit the same tool you already own.
Do masonry blades for a reciprocating saw really exist?
They do. Manufacturers sell carbide masonry blades and diamond grit blades sized for reciprocating saws, and product pages describe uses such as brick, block, fiber cement, fire brick and cast concrete. The common thread is that they are aimed at demolition, repair and opening up small areas, not at precision work.
It helps to be realistic about what a reciprocating saw is. The blade moves in a short stroke, and the saw is not designed to hold a perfectly straight line through a thick slab. Published descriptions of diamond grit blades often say they suit abrasive masonry and block repairs rather than full-depth thick cuts, and that is a fair way to think about the whole category.
Carbide versus diamond grit: how to choose
The right pick depends on the material and how clean you need the cut to be. Here is a general comparison.
If you want to see specific models side by side, our best reciprocating saw blade for concrete comparison lays out the published specifications so you can match a blade to your saw and job.
| Feature | Carbide-tipped | Diamond grit |
|---|---|---|
| How it cuts | Chips and crushes with hardened teeth | Grinds with bonded diamond particles |
| Best for | Brick, block, cinder block, softer masonry | Hard or abrasive material, fire brick, tile, cast concrete |
| Cutting speed | Usually faster in soft masonry | Often slower, but lasts through abrasive material |
| Cut quality | Rougher, more vibration | Smoother edge, less chipping |
| Rebar | Not suited to cutting steel | Not suited to cutting steel |
What these blades cut well, and what they do not
Masonry blades shine on small, practical jobs. They are good for notching a block wall for a pipe, trimming a brick, opening a hole in a cinder block, cutting a section out of a patio paver, or cleaning up the edge of a repair.
They struggle with large or deep work. A thick structural slab, a long straight line or a deep trench cut will be slow, hard on the blade and tiring for you. For that kind of work, a circular saw with a diamond blade or a rented wall saw is a better tool.
- Good fit: block, brick, pavers, fiber cement, fire brick, small concrete repairs
- Fair fit: thin concrete where a rough cut is acceptable
- Poor fit: thick slabs, long straight cuts, reinforced concrete with heavy rebar
- Not a fit: cutting steel rebar (use a metal-cutting blade or a different tool for that)
How to cut concrete with a Sawzall step by step
Technique matters as much as blade choice. Going slowly keeps the blade from overheating and gives you better control.
Follow these steps for a cleaner result.
- Mark your cut line with a pencil or chalk, and clamp or brace the work if it can move.
- Install the masonry blade fully in the clamp and make sure it is locked in.
- Set the saw to a low or medium speed, and turn off orbital action if your saw has it.
- Rest the shoe against the surface and start with a light scoring pass to create a groove.
- Let the blade do the work. Use steady, light pressure and avoid forcing it.
- Pause now and then to let the blade cool, and clear dust from the cut.
- If the cut slows to a crawl, the blade is likely worn, so swap it instead of pushing harder.
Safety notes you should not skip
Cutting masonry throws fine dust, and concrete and brick dust can contain silica, which is harmful to breathe. Wear a properly rated respirator, work outdoors or ventilate the space well, and keep dust down where you can. Wearing safety glasses or goggles is essential, since chips and fragments can fly. Hearing protection is smart, because a reciprocating saw cutting stone is loud.
Wear gloves, since the blade and the cut edge can both be sharp or hot. Never cut into a wall or slab until you know what is inside it, because hidden electrical wiring, water lines or gas lines are a serious hazard. If you are working on a ladder or at height, make sure you have stable footing, because a saw can kick back or bind in masonry. Unplug a corded saw or remove the battery before changing blades.
When you are ready to shop, our reciprocating saw blade for concrete page is a good place to compare length, material and fit across several options.
Getting more life out of your blade
Masonry blades wear faster than wood or metal blades, so a few habits will stretch their life. Use a lower speed, avoid pressing hard, and do not twist the blade in a tight cut. Keep the saw moving along the line, because stalling in one spot builds heat.
Choose a blade length that matches the job. A shorter blade is stiffer and less likely to flex, while a longer one reaches deeper but can wander. Check that the blade shank matches your saw's clamp before you buy.
Frequently asked questions
Can I use a regular metal-cutting blade on concrete?
No. Metal blades have fine teeth that are not hard enough for stone and will dull or break quickly. Use a carbide or diamond grit blade made for masonry.
Will a masonry blade cut through rebar?
Not well. Rebar is steel, and masonry blades are designed for stone-like material. Cutting rebar usually needs a metal-cutting blade or a different tool, which is a separate step from cutting the concrete.
Should I use a wet or dry cut?
Most reciprocating saw masonry blades are used dry. Never spray water near a corded saw or battery contacts unless the tool and blade are made for it. Follow the manufacturer's instructions.
Why does my blade smoke or slow down?
Heat builds up when you press too hard, run the saw too fast or stay in one spot. Back off the pressure, lower the speed and let the blade cool. If it still struggles, it is probably worn out.
