Vermont American 16672 1/2-Inch by 7/8-Inch Useable Length Rounded Tree Metal 1/4-Inch Shank Rotary File for Drill

Had to ream out a bolt lock plate, this chewed through it quickly. Others had failed to do the job.

I used this to fix some doors that wouldn't close in our house. Worked well to grind the striker plate.

Works well, decent quality.

This was able to go slowly through the structural material under my car. It's possible that I was using the wrong tool or using it wrong. But I popped it into my 18V drill and it widened the hole that the drill made.

Works Great!!!

Good reamer.

Awesome
