Ultimate Precision: Double Cut Carbide Rotary Burr for Finest Material Shaping Review

Couldn't remove the factory rivets from the truck frame to replace the cross member due to their location. I cut off the heads with a standard grinder/cutting wheel, then bought them and used a dremel to carve them. I totally wore some of them down, but was able to get work done that I had no other reasonable way to get done. As a disposable tool, they worked well and didn't cost unreasonable money.

I bought this because I had to cut off some of the granite (note they aren't designed for that in my opinion) so I can install a top flush tank.I had no idea how durable granite was.I was sure I would be breaking all bets when I tried to do the job it took a long time (no mistake on the stakes) but to my surprise it didn't break and I put a lot of pressure on for over 10 minutes they should be more than enough if you're using working wood.

I used 1/4" drill bits to open holes in 1/8" sheet steel. More than a few times the material caught so hard on the burr that the burr popped out of the material and the mill stopped. I thought the burr was definitely broken but upon inspection everything was fine. Not broken. Don't bend. The hardness is also very surprising. The millstones I have used have retained their sharpness despite some wear and tear. I would buy this item again and recommend it.
