While I have only used one of these so far to deburr some freshly drilled holes in a piece of 3/8" sheet metal it did a great job.This is probably good for countersinking the holes too but I haven't done that - yet.Good for deburring the inside of tibing/pipes as well.The 1/4" hex shank will fit into almost any drill or 1/4" drive power tool with a 1/4" chuck.These appear to be very well made and perform quite well. No complaints.Good deal for enough grinding bits to last for years. Glad I got these.
