Irwin HSS Jobber Length Drill Bit, 3/8" Reduced Shank, M-2 High Speed Steel

Irwin 1/2" Reduced-Shank Jobber Length Drill Bit

The Irwin 1/2" Reduced-Shank Jobber Length Drill Bit is built from M-2 high-speed steel, engineered for strength, heat resistance, and wear resistance in general-purpose drilling applications. This jobber-length bit features a 118° chisel-tip point that provides clean starts and helps prevent the bit from walking off-center when starting a hole. A 3/8" reduced shank allows this 1/2" diameter bit to fit standard 3/8" drill chucks, giving it broader compatibility with drills that would otherwise be limited to smaller-diameter bits. Designed for versatility, this drill bit is suited for drilling wood, metal, and plastic, making it a practical choice for technicians, contractors, and DIY users who need dependable performance across multiple materials.
