By far, this countersink has outlasted all other brands hand down. I have utilized this countersink to bore material that the bit should not be used for and it has outlasted any other bit I have tried. I have even re-pointed and continued to use this bit when any other bit has nothing left to sharpen or re-point.

This is a well made product. I use it to smooth off the rough shoulder created by drilling holes in metal and also to debur the inside mouth of cartridge cases after trimming. It fits in a 1/4 inch drill chuck so I can use my lightweight cordless drill. Oh yeah, you can use it like a countersink also!
