Guhring 9002050025500 Jobber Drill Bit 2.55 Mm Hss

Product Description

The GUHRING 9002050025500 is a high speed steel jobber-length drill bit designed for general-purpose drilling in metalworking applications. Built to DIN 338 standards, it features a 2.55 mm diameter, a 118-degree standard point angle, and an oxide coating that reduces friction and provides light corrosion resistance during service. The two-flute spiral design with a regular helix and web-thinned, tapered web geometry promotes chip evacuation and reduces thrust at entry. Machinists, tool-and-die techs, and maintenance professionals working with steel and cast iron use this bit for precision hole-making in production and repair environments.

This bit is suited for drilling cast iron and steel workpieces in both light production and maintenance settings. The straight-cylindrical shank seats directly in standard drill chucks on drill presses, CNC machining centers, and hand-held power drills. With an overall length of 57 mm (approximately 2.24 inches) and a flute length of 30 mm (approximately 1.18 inches), it fits within compact work envelopes. The Series 205 designation places it within a well-established DIN 338 jobber-length family used across general machining trades.

Key Features

• 2.55 mm (0.1004 inch) diameter ground to a tolerance of +0.000 to -0.014 mm for consistent hole sizing
• 118-degree standard point angle with web-thinned, tapered web to reduce entry thrust
• M2 high speed steel construction for toughness and heat resistance in ferrous materials
• Oxide coating reduces friction and provides basic surface protection
• Two spiral flutes with regular helix for efficient chip clearance
• DIN 338 specification ensures dimensional interchangeability with standard jobber-length tooling

Compatibility

Designed as a DIN 338 jobber-length drill bit suitable for use in standard drill chucks accepting straight-cylindrical shanks. Rated for primary workpiece materials of steel (material code P) and cast iron (material code K).

Installation Notes

Installation and use should be performed by machinists or qualified trades personnel familiar with rotating cutting tools. Secure the straight-cylindrical shank fully in a properly sized drill chuck and verify runout before drilling. Always wear appropriate eye protection and ensure the workpiece is firmly clamped before engaging the tool. Do not exceed the recommended maximum drilling depth of approximately 26.18 mm (1.031 inches) without retracting to clear chips.
