Review on 🧰 YUFUTOL SC-5 Tungsten Carbide Burr Cylinder Shape Double Cut Rotary Burr File with Radius End (1/2" Cutter Dia X 1" Cutter Length) and 1/4'' Shank - Single Piece by Brian Avila

I bought these bits for my new DeWalt 20V grinder. After destroying a lot of Dremel metal parts I just hoped this thing would do my first job before having to throw it away. NOT CORRECT. Not only did he finish the first two hardened metal harness mounts I had to cut out for the shoulder bolt, it still looks brand new. Hole to get an even cut and keep it round. Metal shavings started flying! (Yes, I wore goggles.) I actually cut it and made the hole too big, but it worked out fine. The second fit just as well, and it fit me better. Literally seconds.
