DEWALT Oscillating Tool Blade for Grout Removal, Fast Cutting, Carbide (DWA4220), One Size

Check exactly what blades you need, this one does not fit Bosch machines (Starlock). Needs improvement on description.

Tool did the job for 4mm epoxy grout which is hard to remove. Took a bit of work but does the job great. Needed 3 blades for an area of 40sqm of tiles.

This tool is perfect for removing grout and did the job very well. This one is for thicker grout removal and would recommend having two sizes (thin and thicker) to remove grout in most instances. This tool I would anticipate would last for a few jobs as it's good quality.

I had to redo my entire kitchen floor grout. With as much time as I spent on my knees, I would expect a raise, but I digress... I bought this grout saw and the counter part "normal" dewalt multi-tool grout saw. I used my Dewalt cordless 20V XR multi tool (they fit fine). Of note, I started with a dremel brand grout blade that I grabbed at Home Depot, and it lasted about 15 square feet. I got both of the dewalts here for about the same money I spent on the dremel alone. Kitchen was about 400 square feet. I did 80% of it with this blade. After burning the dremel one up, I switched between this and the normal dewalt, but used this more because the shape allowed it to cut a wider swath with each pass. My grout must have been mixed poorly at install because I had sections that cut like butter, and others that cut like a diamond. Overall I was very happy with the performance of this piece. I applied more pressure and went slower on the hard parts and it would eventually get it out. I did split the blade like others have posted about near the end of the job, BUT I was clearly starting to abuse the tool. I was also easily 20 hours into the job at this point and at least 250 square feet of cutting. I started to torque it in the groove cut by the grout to clean the sides of the tile in one pass, and it started a split. I'm sure if I had not been more gumptious with it, I could have done the whole kitchen with it. Now, comparing it to the regular, straight blade, I cant say it cut any better. It obviously cuts wider, which sped things up a bit, but for the most part, they were equal in their performance. Hope this helps!

Muy buena calidad

Tried the simple blades and they vibrate in every direction and are less easy to control - this arc was much better, and lasted for 2 walls - and still going. Definitely wear a mask and ear defenders as the noise and dust bounces of the tiles straight back at you. Worth the money in my book.

So quick and easy for removing grout between tiles. Amazing!
