An HVAC friend of mine recommended Milwaukee's series of big selfeed bits for the do-it-myself job of retrofitting a radiant, underfloor heating system in our 112-year-old one-room schoolhouse. I like to learn how the pros do things, and as every professional electrician and plumber must know already, these bits work great, but with at least one limitation. Running the tubing for our underfloor radiant heat requires drilling many holes through old 2 1/2" joists and the blocking between them. I began the job yesterday and, I'm afraid, got a little carried away. With a powerful right-angle drill, the bit seemed to stop at nothing and the work went fast. The selfeed tip pulled my 1 1/2" cutter through effortlessly, and to finish off a hole (once the tip punched through and lost its grip) all that was needed was a little pressure from me. The holes were clean, and the chips were everywhere! Nothing would stop this bit, I thought. Little did I know that old-fashioned cut nails had been used to nail down a 1950's plywood subfloor. I soon found one of those nails with my bit, and thinking this thing would go through anything, I waited patiently for it to chew up the nail and spit it out with the chips. Soon I found myself wrestling with the drill, pushing harder and harder, going in from the other side for a counterattack, giving up, trying again, and then finally admitting to myself that the "threads" had been destroyed on the selfeed tip. The nail sat square in the middle of the hole, unbent and barely scratched. Milwaukee sells their bits with an extra tip so when this kind of thing happens work may go on. But being who I am, I soon had the second tip ruined and the job only 40% done. And there's no drilling without that tip. I tried. No go.Read more ›

Regarding the other review - as a plumber in the Virgin islands, I know full well that not only will these bits not eat nails, they are wrecked by them. Cut nails are a much harder and less maliable steel than a regular nail, and also a much harder steel than these bits, which are not carbide. I try to take care not to hit nails when using them. It ruins their cutting edge in seconds. Fortunatle they can be resharpened with a Dremel quickly and I always keep one handy in my truck.

If I cannot avoid a nail, I switch to a bimetal hole saw. While the Selfeed is really a Forstner and planes out the whole hole, a hole saw makes it a lot easier to cut around the nail, and these bits are rated for metal as well (although cut nails will probably rip their teeth off). The downside of the hole saw is that most only drill to two inches, and they are much, much slower than Selfeeds. Also, it's tedious to extract the wood core after each hole. A pro keeps both and keeps his eyes open.
