Guhring 9003050024400 Cobalt Jobber Drill Bit No. 41

Product Description

The GUHRING 9003050024400 is a cobalt jobber length drill bit sized to wire gauge No. 41, with a decimal diameter of 0.0961 inches. It operates with a 118-degree cone relief point and a regular spiral flute configuration, making it well suited for general-purpose drilling in steel and cast iron. The bright, uncoated finish is standard for cobalt-grade tooling where heat resistance and hardness are priorities. With an overall length of 57 millimeters and a flute length of 30 millimeters, this bit fits standard drill chucks and benchtop or handheld drilling equipment. Machinists, tool and die technicians, and maintenance professionals are the primary users.

This drill bit is intended for drilling cast iron and steel in production and maintenance environments. Its DIN 338 compliance makes it a recognized standard across industrial and trade applications. The straight-cylindrical shank with a diameter of 2.44 millimeters and a shank length of 27 millimeters seats securely in standard keyless or keyed chucks. The web-thinned tip reduces thrust force at entry, which is useful when working in harder ferrous materials or when hole location accuracy is required. It is sold individually with a minimum order quantity of 10 units.

Installation Notes

This bit is installed by machinists or maintenance technicians using standard drill presses, CNC machines, or handheld power drills equipped with an appropriate chuck. Confirm the chuck is fully secured and the workpiece is clamped before beginning drilling operations. Coolant-through is not supported; apply external cutting fluid manually when drilling harder steel grades to extend tool life. Inspect the cutting edges before each use and replace at the first sign of chipping or dulling to maintain hole tolerance.
