I agree with some of the posts.

I have a different model - 3/4" max size - and it turns a rounded
tip - not two flats. I can cut cross points - that is great.

I saved a chipped 3/4" drill - high quality - and after grinding
it I then hand ground the flutes for a undercut from the cutting edge.

I do a lot by hand, but preform some extensive jobs with mine.
