The DEWALT DWA4219 Oscillating Carbide Grout Removal Blade is a straightforward accessory: a carbide-edged blade for oscillating tools that grinds out old grout fast. It uses the universal fit interface, so it mounts on all major oscillating tool brands without an adapter. If you're prepping for tile repair or replacing cracked grout, this is the blade to keep in your kit.
Oscillating tools are ideal for grout work because the back-and-forth motion keeps the blade inside the joint and gives you precise control. The carbide edge on the DWA4219 cuts through hard grout without the glaze that comes with ordinary abrasive blades. That means less dust, fewer blade changes, and a cleaner line.
This blade is built with the universal fit system, so it attaches to most major oscillating tool brands. You don't need a proprietary adapter or a special hub. Just line up the blade with your tool's mounting flange, tighten, and start cutting.

An oscillating tool with a carbide blade keeps grout dust close to the joint, unlike a rotary grinder. The DEWALT DWA4219's carbide edge removes old grout while the narrow blade stays inside the joint line.
The universal fit works on your current tool, so you don't need to buy into a new system to improve your grout work.
Yes, the DWA4219 uses the universal fit interface and is compatible with all major oscillating tool brands without an adapter.

Loosen the tool's clamp, slide the blade into position on the mounting flange, and tighten the clamp. The universal mount fits standard oscillating tool attachments.
No, it is designed for grout removal. Use a diamond tile blade for cutting tile itself.











This blade made grout removal a breeze. I re-tiled my shower and it saved me hours.
I've been in the tiling business for 30 years and this is the best grout removal blade I've used. It cuts through grout aggressively without chipping the tiles. The carbide edges are still sharp after multiple bathrooms. It fits my oscillating tool perfectly, no adapter needed. It's worth the price.
It removes grout quickly, but it makes a lot of dust. Use a vacuum.
I was going to replace my whole floor because of old grout. This blade let me just clean it out and re-grout. Huge money saver.
It works, but it's hard to control at first. Practice on scrap.
This blade chews through thick mortar joints. It doesn't clog. Very pleased.
I'm a DIYer and this blade was easy to attach and use. It made the job simple.
It does the job, but the universal fit isn't perfect on my tool. Still works.
This blade is amazing. My husband used it to remove grout in our bathroom and it went much faster than expected. The cuts are clean and it doesn't leave gouges.
Works fine.
Two bathrooms done and it's still sharp. Great blade.
