Review on 🔩 Milwaukee 48-25-2001 2" x 16" Selfeed Auger Bit by Trevor French

If you want to pass the drain pipe through the studs, you need to drill several holes. The augers and vanes only fit up to an inch and a half - that's the size of the pipe, so there aren't any. You'll need to drill at least 2" holes, leaving you with self-tapping screws or crowns. Crowns are cheaper, but they are also slower. You must stop after each hole and remove the used cork from the crown body. Much time. If you hit a nail with a hole saw, it's game over. Self-tapping screws can be sharpened with a file. On the other hand, with this self-feeding nozzle you don't have to stop to take out the plugs - there are no plugs - just a nice pile of wood shavings. A self-feeding drill has a lead screw that pulls it through the workpiece. All in all a pleasant and smooth process. I used this bit when adding a sink to my laundry room. Starting the bleed drains wasn't a problem as this drill bit made the right size holes for me. The only downside to this drill bit is that it requires a 1/2" drill bit to work. (But the same goes for most large crowns.) A 7/16 shank also requires a 1/2" chuck. Self-tapping bits also usually require a drill with some power. My Milwaukees haven't had any skidding issues, neither has mine 14.4 Makita, My Ridgid impact drill or my Metabo angle drill This is a pretty serious part that usually costs a decent amount of money (around $30) so I'm more wary of it than other parts that cost less.I try not to walk into nails whenever possible I use the side handle of the drill bit I'm working with so I don't injure myself if the bit gets stuck in the wood while the bit continues to work.
