OK.
good product
Doesn't do to bad of a job, what else can you expect for a small amount of money. Best to buy a smaller size then you want and clean out and straighten up with a chisel. I have a very good drill press with not slop and the bit doesn't cut perfectly but it's a lot quicker then by hand and easy to clean up after with a good sharp chisel.
Very good
