Review: Readily "ate metal"! - Used these rotary cutting burrs, along with some drill bits, to remove the lock from an old fireproof filing cabinet. These burrs worked like a champ! At the end of the project the lock had been reduced to a small box of brass shavings, And most of the work was done by these burrs. The roughly 6 inch overall length of these burrs made them just the right tool to "grind out" the lock, after I'd drilled through the tumblers. I'd buy these again in a heartbeat, but it looks like I'll be able to use them for a lonnnnnng time to come. Definitely got my money's worth. And the variety of tip shapes actually helped get the work done, no matter what the angle of the battery drill I was using. Great product for the home handyman!

### ⭐⭐⭐⭐ Not for high speed use
*by E***S on December 10, 2021*

Mine turned into a wet noodle the moment I turned on the porting tool, it went out of control. One exploded, all had to be cut down to about 3 to 4 inches to be able to be used, I really needed to reach the places that these were supposed to go.
