Guhring 9002060067500 Letter H Hss Jobber Drill Bit

Product Description

The GUHRING 9002060067500 is a jobber-length twist drill bit in Letter H sizing (0.2656 inches decimal equivalent), manufactured from high speed steel (HSS) with a bright, uncoated finish. The 118-degree cone relief point geometry suits general-purpose drilling operations, while the slow spiral flute design is optimized for chip evacuation in aluminum and non-ferrous materials. The web-thinned tip reduces thrust requirements at entry. Overall length is 4.2913 inches (109 millimeters), with a flute length of 2.7165 inches (69 millimeters). This drill is built to DIN 338 standards and carries an h8 diameter tolerance on the shank. HVAC, plumbing, and mechanical contractors will find this bit reliable for sheet metal, aluminum fittings, copper, and similar soft-metal work.

This jobber drill is suited for light-to-medium drilling in aluminum, copper, brass, and other non-ferrous workpiece materials. The straight cylindrical shank fits standard drill chucks in both hand-held and bench drill press applications. The 5xD flute-to-diameter ratio delivers adequate chip clearance for the drilling depths common in trade service work. No coolant-through capability is present, so conventional external lubrication or dry drilling applies depending on material and feed rate.

Installation Notes

This drill bit is installed by a machinist, HVAC technician, plumber, or electrician performing field drilling in non-ferrous materials. Secure the straight shank fully in the drill chuck and tighten all jaws before operation. Apply a suitable cutting fluid or lubricant when drilling copper or aluminum to extend tool life and improve hole finish. Do not exceed the drill press or tool manufacturer's recommended feed and speed ratings for HSS tooling in the target material.
