3046009 Speedbor Max Self-feed Wood Drill Bit, 1-3/4 In.

The Irwin Speedbor Max Self-Feed Wood Drill Bit is engineered for drilling large-diameter holes in wood quickly and efficiently. Ideal for applications like boring holes for pipe and conduit systems, this bit features a self-feeding design that drives forward aggressively, reducing the effort needed to bore through wood. The 1-3/4-inch diameter and 3-flute cutting design deliver fast, accurate holes with clean edges.

The precision-milled hex shank eliminates runout and vibration for smooth, stable operation, while the coarse-thread feed screws provide fast boring action. The 7/16-inch quick-change impact shank is compatible with 1/2-inch or larger drills and 7/16-inch hex impact wrenches, making it versatile for various power tools. This bit resists wear and breakage under heavy use and tough drilling conditions.
