Introducing the Milwaukee 1-3/4 in. x 6 in. L Heat-Treated Steel Self-Feed Drill Bit Hex Shank—a purpose-built tool engineered for professional woodworkers and serious DIYers who demand fast, clean, and reliable large-diameter holes. Built around a rugged, heat-treated steel core and a precision-coated finish, this bit is ready to tackle demanding cuts with less effort and more control.
Why this bit stands out
-
Durable construction: Heat-treated steel handles tough jobs and resists wear, so you can reach deeper into projects without the bit dulling quickly.
-
Coated for performance: The protective coating reduces friction and slick buildup, helping you maintain steady progress and cleaner edges.
-
Self-feed design: The integrated screw tip pulls the bit into the material, delivering fast, controlled entry and fewer stalling moments—ideal for drilling large holes without heavy pushing.
-
Hex shank for secure grip: A 7/16" hex shank locks into the chuck with minimal slippage, enabling higher torque transfer and smoother operation when you’re drilling through dense wood.
-
Precisely sized for big holes: 1-3/4" hole capability with a 6" overall length and a 3/4" flute length, giving you a deep bore while maintaining balance and control in hand or on a drill press.
-
Single, ready-to-use piece: Packaged in a clamshell, each piece is ready to deploy on the job site—no need to hunt down matching bits.
Perfect use cases
This self-feed bit is ideal for creating large-diameter holes in wood-based materials such as softwood, plywood, and OSB. Use it when you need to run electrical conduit, large-diameter wiring, plumbing passages, or venting through studs and beams. It’s a preferred choice for deck builders, cabinet makers, furniture fabricators, and general contractors who require quick, precise bores with minimal effort.
What makes it better than traditional alternatives
Compared to standard twist or spade bits, the Milwaukee self-feed design accelerates entry and delivers cleaner edges with less bit wandering. The heat-treated steel and coated surface extend bit life in repetitive drilling tasks, while the hex shank minimizes chuck slippage under high torque. For larger-diameter holes, this combination translates to faster work, fewer passes, and more consistent results.
How to get the best results
- Use a steady, moderate feed rate and let the screw tip do the work—avoid forcing the bit, which can cause tear-out or drift.
- Keep the workpiece supported and clamped to prevent movement during drilling for the most accurate hole.
- Pair with a drill that accepts hex shanks to maximize grip and torque transfer, especially when drilling through dense wood.
- Clear debris periodically to prevent clogging and ensure a smooth bore path.
