Guhring 9002050166700 Jobber Drill Bit 21/32 in Hss

Product Description

The GUHRING 9002050166700 is a jobber-length twist drill bit designed for general-purpose drilling in steel and cast iron. Built from M2 high speed steel with an oxide coating, this bit delivers consistent performance across production and maintenance drilling operations. It features a 118-degree standard point angle, a web-thinned and tapered web configuration for easier entry, and a two-flute spiral design with regular spiral geometry. The straight-cylindrical shank measures 21/32 inch (0.6563 inch decimal) and seats securely in standard drill chucks. Overall length is 184 mm with a flute length of 125 mm. This is a DIN 338-compliant tool intended for use by machinists, tool-and-die techs, HVAC service technicians, pipefitters, and general maintenance tradespeople.

This drill bit is suited for drilling into cast iron and steel in both shop and field environments. The 5xD flute-to-diameter ratio supports chip evacuation in moderate-depth holes up to 100 mm deep. It is a single-piece, right-hand-cut tool appropriate for use in handheld drills, drill presses, and milling machines with a compatible chuck or collet accepting a 21/32-inch straight shank. The oxide finish provides mild corrosion resistance and reduces friction during cutting. Series 205 is GUHRING's general-purpose jobber drill line conforming to DIN 338 standards.
