ROUGH-IN READY: CLEAN BORE PERFECTION FOR PLUMBING PASS-THROUGHSWhen you're roughing in a stack or running supply lines through dense framing, you need a bit that doesn't fight back. This 3-piece kit is engineered for the high-torque demands of plumbing installations, where clean, burr-free holes are the difference between a smooth pipe slide and a hung-up mess in a tight crawlspace. The inside cutting plane doesn't just hog out material; it shaves the radius to ensure your PVC or PEX passes through without snagging. Built from heat-treated alloy, these bits handle the heat of repetitive boring through pressure-treated lumber, while the replaceable feed screw ensures the bit keeps pulling even after the lead threads take a beating on the jobsite. / Inside cutting plane produces clean, smooth holes for snag-free pipe installation and code-compliant rough-ins. / Replaceable feed screw effortlessly pulls the bit through tough, wet, or treated lumber without requiring excessive operator pressure. / Heat-treated alloy construction provides maximum durability and wear resistance against knots and jobsite debris. / Resharpenable cutting edge allows for quick field maintenance with a standard file to maintain peak drilling speed.
