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!

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.oBad 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...

capable and quick
i used the 3/4" drill for drilling through two pieces of wood that were sandwiched together for a total width of about 2.5 inches. i used a dewalt 18v on the low speed/high torque setting and it didn't have much trouble getting through the wood. the self-feed really does do the work for you, much better than the regular spade bits.update: if i could i would rate this as a 5 star product. it goes through everything i've put it up against. vertical grain fir, old growth wood, etc. it just burns right through. awesome for running wires, plumbing, etc.
