  • Great for cutting mortises!!
These bits are great if you do a lot of woodworking and want to start using mortise and tenant joints in your projects. They cut cleanly and there’s usually no need to clean up your mortise with a chisel when you’re done! Great buy!!

  • 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.

  • Doesn’t fit most drill shucks
Doesn’t work with my Dewalt or my drill press also need to buy another piece for it to work but if it doesn’t fit the chuck what good is it

  • Disappointing product
These are kinda crap. They won't fit in my SKIL table top drill press. I can't lower the plate low enough. So any material I wouldn't be able to get material under the drill. I would need a much larger drill press and the chisel part moves around too much. Pretty disappointing.
