The Irwin 3046011 Speedbor Max is a heavy-duty wood drill bit designed for drilling large-diameter holes through thick wood members. With its aggressive self-feed screw pitch and precision-milled design, it delivers fast, clean boring action ideal for pipe and conduit system installations and other demanding wood-drilling applications.

This bit combines durable construction with an efficient cutting design. The coarse-thread feed screws enable rapid advancement through wood, while the three cutting spurs on the outside diameter ensure accurate, clean hole edges every time. The 7/16 inch hex quick-change impact shank fits standard 1/2 inch or larger drills and 7/16 inch hex impact wrench drills for versatile compatibility.

Features and Benefits

  • Self-Feed Design: The aggressive screw pitch and three-cutter configuration provide exceptional efficiency, cutting approximately three times the cutting area and edges compared to standard self-feed bits.
  • Coarse-Thread Feed Screws: Enable fast boring action for rapid hole completion through thick wood.
  • Precision-Milled Shank: The hex shank eliminates run-out and wobble for accurate, consistent hole drilling.
  • Quick-Change Impact Shank: The 7/16 inch hex shank design fits 1/2 inch or larger drills as well as impact wrench drills, providing flexibility for different tools.
  • Included Accessories: Each bit comes packaged with one hex key and two additional feed screws for replacement or spare use.
