What type drill are you using? Put the bit in a drill press and running medium speed hold a stone to the sides of the bit “lightly ” You can also hold the stone to the bottom of the bit and hone the cutting edges. Always use a bit that size in a drill press medium speed and feed slow.

@papadan, with all due respect, I didn’t ask how to fix a bit, I asked whether I can rightfully expect better. Your answer implies a “yes”, so thank you for that. But I don’t think that the onus of making a brand new bit usable should be on me, so the rest of your answer is, at best, misdirected. I already know how to sharpen bits such as this (and your method seems wrong to me, BTW.)

I think you should expect better. I have a set from Woodcraft that cuts cleanly. Higher cost ones are even better. I have a couple Freud ones that really cut cleanly.

DirtyMike… you should know that magnets will cause the bits to fail. ;-)

Oh heck…........I thought I could help an idiot improve his hole drilling technic and equipment. My bad for not just ignoring your dumb ass!

I’ve got some cheap-ass ones from the BORG (Ryobi I think) that cut as smooth and clean as some more expensive ones. Machined nicely and no rough edges. I’d say yours is out of the ordinary in terms of QC and you should send it back.

Cheers,

Thanks, guys – I think I will send it back. It’s important to send the message that poor quality should not and will not be tolerated. Your feedback is most definitely appreciated.

The Chinese ones definitely come raggedy. and sharpening before use is needed. I have been disappointed from several sources, and now I will only buy bits from Lee Valley for exactly the reason the OP states.
