Great bit for runing drain pipe
If you plan on running drain pipe through studs, you are going to have to make some holes. Augers and spade bits only go up to inch and a half- thats the size of the pipe, so they're out. You need to make holes at least 2 inches, so that leaves you with self feeds or holesaws. Holesaws are cheaper, but they are also slower. You have to stop after each hole and wrestle the spent plug of wood out of the holesaw body. Very time consuming. If you hit a nail with the holesaw, it's game over. Self feeds can be resharpened with a file. On the other hand, with this self feed bit, ther is no stoping to get plugs out- there are no plugs-Just a nice pile of wood shavings. The self feed bit has a lead screw that pulls it through the workpiece. All in all a sweet and smooth operation. I used this bit when I added a laundry sink to my laundry room. Runing the vent drains were no problem with this bit making adequate sized holes for me. The only...

Great Selfeed Bit Chokes on Cut Nails
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...
