Product Details

Why Segmented Rim Blades Are Great for Mortar and Masonry

The segmented rim creates open spaces that let sawdust and debris escape while the diamond segments grind through mortar and masonry. That means faster cutting and less heat buildup in the blade.

Tuck Pointing Tips for Cleaner Results

Use a straightedge to guide the blade and keep the groove depth consistent.
Let the tool do the work—avoid forcing the blade into the joint.
Keep the blade square to the surface to prevent undercutting.

Match the Blade to the Grinder

Always confirm the blade's rated RPM is equal to or greater than your grinder's no-load speed, and use the correct guard for 6-inch blades.

Frequently Asked Questions

Can this blade be used wet?

No, the DW4739S is designed for dry cutting. Adding water can reduce cutting efficiency and may damage the blade. Use a dust mask and vacuum when cutting indoors.

Will this 6-inch blade fit my angle grinder?

Most angle grinders with a 6-inch guard and compatible arbor size will work. Check your grinder's arbor and maximum RPM before installing.

What materials can it cut?

It cuts concrete, stone, and brick. It is not intended for metal or tile.

Cuts fast

Used it to cut a bunch of concrete pavers. It cut fast and didn't chip much.

Excellent for tuckpointing

I do tuckpointing for a living and have gone through many blades. This one is by far the best I've used for cutting out old mortar. The diamond matrix seems to last longer, and the large segments make quick work of deep joints. It produces a lot of dust, but that's expected with dry cutting. The blade didn't warp or bog down even on hard brick. I've cut well over a hundred feet of joints with it and it still has life left. Definitely recommend for professionals.

Good blade

It cuts well and fits my grinder. The only thing is it wears faster than I hoped on some really hard paver. But for the price, it's decent.

Okay, not amazing

It does the job, but I expected it to last longer. I cut about 20 feet of mortar and the blade noticeably dulled. Maybe I got a bad one, but I'll stick to my usual brand.

Great on stone

I used this on some flagstone and it didn't chip at all. The segmented rim helps with smooth cuts. Very pleased.

Does the job

I'm a DIYer and this blade did what I needed. It cut through a brick wall for a vent. A little dusty, but fine.

Good value

The blade is okay for the price. It cuts brick, but it wears a bit fast. For occasional use, it's fine.
