I had to relocate a drain line in our laundry room, and figured it was going to be a bear of a job, considering the size of the hole… but with this bit, it turned out to be prettY easy… that spiral screw on the bit pulled the darn thing thru the 2x4 with ease… no effort on my part other than guiding the drill…. MADE AN IMPOSSIBLE JOB EASY

As a Plumber I drill quite a few holes in wood for my drains and vent piping, paired up with my Dewalt 60v joist drill ( also from Amazon) this bit bites in with ease to drill my 2 9/16" holes. As with all drills of this type, nails are a no no, got it on sale $40 cdn. Puts the same Milwaukee bit to shame.

To help out with my long-delayed garage interior build-out, I bought this bit so I could drill holes through 2x4 and 2x6 wall studs and framing for routing the 2" PVC drain pipes needed for some sink installations. This bit is made really well and works great, but the standard electric (corded) 1/2" drills didn't have enough torque to keep the bit cutting due to the rate at which the aggressively spiraled flutes on the outside of the self-feed tip pulled the bit into the wood. It was also about as much as my old wrists could stand, too! :-( Since each bit comes with an extra feed tip, I resolved the problem by using a grinder to remove the tops of the spiraled flutes so that the tip would still center the bit in the hole being drilled but allow me to control the feed rate based on the amount of downward pressure being placed on the drill. This bit is precision cast and ground, and cuts a very clean hole even when the board is well-seasoned and tough. Further, the casting is robust enough so I believe that it could be re-sharpened at least once if needed. Despite the "star" I deducted due to the excessively high self-feed rate issue I needed to resolve, I'd definitely buy this bit again. However, unless I could use it with a drill press, I'd simultaneously plan on buying a heavy-duty 3/4" hand-held electric drill due the amount of torque it calls for and resultant stress it puts on a drill and the person using it!

I was trying to make a hole with the grain in a 5 inch diameter piece of Osage Orange wood. I might as well been trying it in a billet of steel! Osage cuts easily with a chain saw and splits well, just don't try to drill a very big hole in it. This tool worked quite well for a ways then it dulled enough I had to quit using it, but no other tool would do the job either. This tool would have been fine in any "normal" wood. ej
