  • Good quality
These were good quality, but unfortunately they did not fit my Delta drill press, tenoning jig. These are 3/4 inch shank which I found out is common. Delta tenon jigs use a 5/8 inch shank chisel.

  • you need a special attachment on drillpress to use this product.
I was not aware you needed a special machine to use these drill bits. I have not been able to use them at all to give an honest opinion. It should have been mentioned in the advertising on the site. I am not a happy camper.

  • They don't work
Did a test on a piece of 2x4 and it would only penetrate about a quarter of an inch. Drill bit function could not remove material but it did burn the wood. Not a usable product for me.
