TOWSON, Md. — IRWIN®, a provider of hand tools and power tool accessories, launched its SPEEDBOR SUPREME™ self-feed bits and auger bits. The new line of SPEEDBOR SUPREME bits are engineered for high performance wood drilling and are designed to withstand repeated nail strikes. The bits’ high-speed steel cutting edge maintain sharpness due to the durable bi-metal construction.

IRWIN SPEEDBOR SUPREME self-feed bits and auger bits are sold in a variety of lengths and diameters, allowing users to tackle challenging wood-drilling needs with ease. The bits are made to deliver fast, high-performing drilling by cutting through both clean and nail embedded wood and feature a re-sharpenable cutting edge, aggressive screw tip, and black oxide coating for enhanced corrosion resistance.

SPEEDBOR SUPREME Self-Feed Bit Features:

The self-feed bits have a high-speed steel cutting edge and an aggressive screw tip that quickly drills through lumber. Engineered to cut through the most challenging drilling applications, IRWIN SPEEDBOR SUPREME 2-9/16-inch self-feed bit drills 6.3X holes vs. IRWIN’s previous model, when drilling into 1-1/2-inch thick Brazilian oak hardwood. Designed to make quick, clean holes with minimum interruptions, the self-feed bits have an extended shank that can cut 4-by-4-inch lumber without extensions and an included replacement tip. The self-feed bits can be used in standard drill chucks and the 7/16-inch quick change hex allows for compatibility with quick change ready right-angle drills. The self-feed bits are suited for drilling holes to run electrical cabling; conduits; and PVC pipe for water, drain and waste lines. For more information, visit
