Customer Reviews

Vary nice, but not quite tough enough
***Revised 1/7/07, not made for thick material see bottom***

I bought a 5/8 for my cordless drill for your standard hole to run electrical wires through. And found it puts less stress on my motor and drills a lot smother than a standard auger bit (it doesn't "chew" the wood, it drills it out) so I bought the set. They also leave a pretty clean hole, witch I've found to be useful when drill a 2x4 diagonally. So far they have not slipped or ripped they're selves away from work where I don't have full surface contact. It stays pretty sharp I've probly drilled well over 400 holes with the 5/8 I mentioned and is still plenty sharp to be useful.o

Bad things:

Not all precisely made, many I've tried out seem to be bent or warped a little. They still work fine though, it doesn't seem to effect they're performance at all.

NOT a nail eater, if you hit hard metal like a big nail or a cable staple (or masonry) you will have to touch it up with a file (a rounded file, that most don't carry with them). It's got good tempering and toughness for wood and wood like materials but it's just not a vary hard/metal. Try out Greenlee's auger bits, they seem to have the best ware resistance and toughness.

Not made for deep holes. Every time I drill DOWN/SIDEWAYS through something thicker than a 4/4 the bit sort of get`s stuck behind the waste martial. Though most bits like this do that.
As long as you're not drilling blind all the time and in 2x4 or less type wood they are well worth the money, if they where made out of some harder metal, longer flutes and made truer they would have gotten a five star review at this price easy.

*Revise*
All but the biggest 3 ("7/8, "1 and "1-1/4) want to get stuck on anything thicker than a 2x4 if you're not drilling upward. Also my Dewalt DC988 drill can make holes with the "1 and "1-1/4 bit, but puts it in a good strain (first gear of corse). If your going to be making multiple holes with the largest two I'd bring out a 6 amp+ corded drill.

Clean, rapid cutting
These are a tremendous improvement over the standard spade bits.

They drill much more quickly because they are spiraled like a bit, rather than just chipping away. They also drill perfectly round, smooth holes without splintering the surrounding wood. Once you see this in action, you'll never go back to the old spade bits again.

Fantastic for running wire/pipe in a remodel
If you just want to bust through SYP#2 in an addition, or basement remodel, throw one of this bits in your corded drill and watch out! Man, I've never drilled a faster hole, even with Milwaukee auger bits in a HoleHawg. So goodbye to burning through regular paddlebits....these are time savers for real! Buy the six pack---you'll know out the job faster than ever before, and want be tired from fighting the drill all day!
