Guhring 9002050013800 Jobber Drill 1.38mm Hss Din 338

Product Description

The GUHRING 9002050013800 is a high speed steel jobber-length drill bit designed for general-purpose drilling in ferrous materials. It features a 1.38 mm diameter, a standard 118-degree split point with web thinning, and a bright uncoated finish. The straight-cylindrical shank seats directly into standard drill chucks without adapters. Built to DIN 338 specifications and manufactured from M2 HSS, this bit delivers consistent performance in production and maintenance drilling applications. It is sold individually and suited for use in drill presses, CNC machining centers, and handheld power tools.

This drill bit is intended for drilling cast iron and steel in both light manufacturing and maintenance environments. The Series 205 designation places it within a well-established jobber-length format, making it a standard choice for machinists, millwrights, and industrial maintenance technicians who need a reliable small-diameter drill in the 0.05 to 0.10 inch size range. The 2-flute spiral design provides efficient chip evacuation during through-hole and blind-hole operations.

Key Features

• 1.38 mm diameter with a diameter tolerance of +0.000 to -0.014 mm for close-tolerance drilling
• 118-degree standard point angle with web-thinned, tapered web for easier entry into ferrous materials
• M2 high speed steel construction per DIN 338 for general-purpose durability
• Bright uncoated finish suitable for use with cutting fluid in cast iron and steel applications
• Right-hand cut, regular spiral, 2-flute design with a 5xD flute-to-diameter ratio
• Straight-cylindrical shank compatible with standard drill chucks; no coolant-through feature

Compatibility

Designed as a general-purpose jobber drill for use in standard drill chucks and collets accepting a 1.38 mm straight shank; primary workpiece materials are cast iron and steel per DIN 338 material codes K and P.

Installation Notes

This drill bit is installed and serviced by machinists, millwrights, and maintenance technicians. Secure the straight-cylindrical shank firmly in a keyed or keyless chuck before operation, and verify runout is within acceptable limits before drilling to maintain diameter tolerance. Use an appropriate cutting fluid when drilling steel to extend tool life and improve hole finish. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.
