    Good clean holes but takes a powerful drill, August 4, 2011

    I have had these for a short while and find I use them more and more when I can. These bits are FAST, and they cut a nice round hole. They chunk out LARGE wood shavings, you can see why they cut so fast, they cut a lot on each spin. However, the piper must be paid his due, and in the case of these bits, you need a large, powerful drill to run them well. I have seen some comments here on sloppy exit holes, which has not been my experience at all, I’ve gotten nice clean exit holes, and I wonder if that’s caused by running them with too small a drill. I would use a corded drill whenever possible (These things have sucked my 18 volt lithium 1 amp drill batteries dry in less than half a dozen holes in 4×4 post stock) and it should be something big like a 3/8 drive, minimum. With a smaller drill they will bind in the hole and twist your drill (and wrist). Also unlike others here, I have had no trouble running them through deep 4″ stock, BUT you have to back them up to clear the shavings a LOT. They do not throw out the shavings behind the bit well. However, I consider that a small inconvenience, I’m still drilling faster using these and clearing the shavings than with twist bits and much faster than spade bits. I’m not sure how they rate against my other augers, maybe about the same for speed, but my augers cost more for each bit than this entire set did, so I think this set has a good deal of value to it.

    Another con is that you shouldn’t even think about trying these at more than a few degrees of angle from the wood surface. They need to go straight into the face of the board, or they will run, not walk across your work, dragging that pilot cone like a router bit, digging an unwanted groove in the work.

    Pros – fast, clean holes, clean entry, clean exit.
    Cons – Need a powerful drill, clogs with shavings, cannot be used at any kind of angle.

    Vary nice, but not quite tough enough, December 31, 2006

    ***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 2×4 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, the nail eaters 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 2×4 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 2×4 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 low spead (geared/high torque ) corded drill.

    Fantastic for running wire/pipe in a remodel, July 27, 2007

    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!
