I'm a remodeling contractor. This is the best bit I've found for boring through studs or joists when doing plumbing rough-in work. The bit basically pulls itself through the wood and chews up everything on the way through.

I use my DeWalt DW120K right angle drill but you could use a hole hawg etc. Use a heavy duty 1/2" drill, preferably one that you can hold with 2 hands because if this gets stuck on a nail etc. while drilling the torque of the drill can really painfully wrench your arm.

One great thing is that can send the bits out for resharpening although will they last a long time before you have to. Get a 2 9/16ths bit for running your 2" pipe and a 12" hex bit extender because the shank is only about 3" long.

I made this bird house/motel out of a 4 x 6 timber, that is approximately 6 feet tall. I drilled large holes to the actual douglas fir timber with this Milwaukee bit w/out any problems. I used the regular corded Hilti drill. I opted not to use the Milwaukee impact drill or the cordless hammer drill b/c it does use a lot of battery power. It makes a nice clean hole, and the center spike keeps it perfectly aligned. Watch out b/c if you're not careful it can really damage your wrist, b/c once it starts it keeps going. For those curious, I then put some redwood boards on the timber and made smaller holes. It looks as if a woodpecker made the holes. The project looks nice as far as decor goes, but so far no birds have nested in it.

Great for boring holes for 1 1/2" PVC pipe in wood studs. Plumbers always have this size when roughing in venting for remodels or room additions. The quality is good and lasts a long time, especially if you don't hit nails or screws in the wood. Expensive initially, but if you need it you gotta get it

I order these several times a year. I usually order them from a local business but the price is $10.00 more each with that company. Great Price!!!!
