The DEWALT DWA4241 diamond-grit oscillating blade removes grout and mortar fast, with universal fitment for all major multi-tools and no adapter needed.
Categories : tools
SKU : WOR-TOO-755
The DEWALT DWA4241 is a diamond-grit oscillating blade designed to make short work of grout, mortar, and thinset. Its synthetic diamond coating handles aggressive material removal while the swing shape lets you get into tight spaces between tiles. Best of all, it fits all major oscillating multi-tools without an adapter, so it's a drop-in upgrade for your existing tool.
Diamond is one of the hardest materials available, and bonding it to a durable steel blade gives you a cutting edge that lasts far longer than standard carbide or high-speed steel blades. When you're on your knees removing old grout, a longer-life blade means fewer trips to the toolbox and more consistent cuts.
No adapter required—this blade mounts quickly on DEWALT, Milwaukee, Makita, Bosch, Fein, Rockwell, and other oscillating tools with standard mounting systems. Just match the blade to the tool's arbor, tighten, and you're ready to cut.
If your oscillating tool has been sitting in the cabinet because the blades wear out too fast, the DWA4241 is the blade that will make you reach for it again.

Grout removal is one of the most abrasive jobs on a jobsite. The DEWALT DWA4241 diamond-grit blade is engineered to survive that punishment and keep cutting. The synthetic diamond coating resists wear, so you spend more time working and less time swapping blades.
If you have more than one brand of oscillating tool on the truck, this one blade works across all of them. No need to stock separate blades for each tool. That's one less thing to think about.
Let the tool do the work and use light, steady pressure. Pushing too hard can overheat the blade and shorten its life. Keep the blade flat against the surface, and clean it after each use to prevent grout from hardening on the diamond edge.
Yes, it is designed for universal fitment on all major oscillating multi-tool brands. No adapter is required.
Absolutely. The diamond grit edge is specifically designed for aggressive grout and mortar removal under tile.
Diamond grit typically lasts longer and cuts faster on abrasive materials like grout and mortar, so you replace it less often.
No adapter is needed. The DWA4241 mounts directly on tools with the standard oscillating blade mount.
This blade is optimized for masonry materials. For wood or drywall, use a dedicated wood-cutting or bi-metal blade.


Cuts grout fast.
Works with my Fein tool. It removes grout without damaging the tile.
I've removed a lot of grout in my time, and this blade is the best I've used. It cuts through quickly and doesn't clog. The universal fitment is nice. I used it on a shower re-tile and it saved me hours. The blade still has life left after a full bathroom. Definitely worth the money.
Sharp little blade.
It fits my Dremel Multi-Max perfectly. It chews through grout like a champ.
I had to remove old grout before retiling my kitchen. This blade made the job doable. It's aggressive but doesn't scratch the tile. The universal fitment meant I didn't need an adapter. I'm not strong, but this worked well. It got the job done.
Works great.
My husband used it to remove grout. He said it was much easier than expected.
I'm a tile setter and I've gone through many grout blades. This one lasts longer than most. It cuts fast and leaves a clean groove. The universal fit is convenient. I appreciate that it fits all my oscillating tools. The diamond grit is doing its job. Highly recommended.
It's a blade.
Good blade for the money. It removed grout and mortar efficiently.
I hired a contractor who used a blade like this, so I bought one for a small project. It works well even in tight spaces. The blade didn't bend or break. The grout came out easily. I'm very pleased.
Great for DIY.
The blade is sturdy and cuts well. It fits my oscillating tool without issue.
This is the second one I've bought. The first lasted through a whole house. It's nice that you don't need adapters. It cuts clean and fast. The packaging was good. I'll keep buying these.
