The Irwin 3046008 Speedbor Max Self-Feed Wood Drill Bit is engineered for boring large-diameter holes in wood, pipe, and conduit applications with speed and precision. This 1-1/2 inch bit features a coarse-thread feed screw for fast boring, combined with spurs on the outer diameter that cut holes clearly and accurately. The forged, high-carbon steel construction provides exceptional durability under demanding drilling conditions.

The 7/16 inch hex quick-change impact shank enables use in impact-ready drills and impact wrenches for large-diameter hole drilling applications. The precision-milled shank eliminates run-out and wobble for consistent, true holes.
