Guhring 9002050031200 Jobber Drill 3.12mm Hss Oxide

Product Description

The GUHRING 9002050031200 is a jobber-length twist drill bit designed for general-purpose drilling in ferrous metals, cast iron, and steel. Built to DIN 338 standards from M2 high speed steel with an oxide finish, it delivers consistent performance in production and maintenance drilling applications. The 118-degree standard point angle provides a reliable entry geometry for most metal drilling tasks. At 3.12 mm in diameter with a 65 mm overall length, this bit suits benchtop drill presses, hand drills, and CNC drilling operations where a compact, straight-shank tool is required. The 2-flute spiral design clears chips efficiently while maintaining concentricity through the cut.

This drill bit is rated for use in cast iron and steel workpieces, making it a practical choice for fabrication shops, maintenance technicians, and toolroom applications. The straight-cylindrical shank allows direct chucking in standard keyless or keyed drill chucks without adapters. With a flute length of 36 mm and a maximum drilling depth of 31.32 mm, it handles through-hole and blind-hole work within its size class. The web-thinned, tapered web configuration reduces thrust requirements and improves chip flow at the tip.

Key Features

• DIN 338 standard — consistent geometry and tolerances for general-purpose metal drilling
• M2 high speed steel construction with oxide coating for corrosion resistance and reduced friction
• 118-degree standard point with web thinning reduces entry thrust and improves centering
• 2-flute regular spiral flute design promotes effective chip evacuation in steel and cast iron
• Straight-cylindrical shank compatible with standard drill chucks — no adapter needed
• Diameter tolerance of +0.000 to -0.018 mm for consistent fit in close-tolerance applications

Compatibility

Designed as a general-purpose jobber drill for use in steel and cast iron workpieces per DIN 338 Series 205 specifications. Suitable for use in any standard drill chuck accepting a 3.12 mm straight-cylindrical shank.

Installation Notes

This drill bit is installed and serviced by machinists, toolroom technicians, and maintenance mechanics. Secure the shank fully in a properly sized drill chuck and verify runout before drilling. Use cutting fluid or coolant appropriate for the workpiece material when drilling steel to extend tool life and maintain hole quality. Do not exceed the rated maximum drilling depth of 31.32 mm without retracting to clear chips.
