Guhring 9002050016500 Jobber Drill Bit 1.65mm Hss

Product Description

The GUHRING 9002050016500 is a jobber-length twist drill bit engineered for general-purpose drilling in ferrous materials. Ground from M2 high speed steel with a bright uncoated finish, the bit features a standard 118-degree point angle, a web-thinned tapered web, and a two-flute regular spiral geometry that efficiently evacuates chips during through-hole drilling. The straight-cylindrical shank measures 1.65 mm in diameter and seats directly into standard drill chucks or collet systems without adapters. Manufactured to DIN 338 tolerances, diameter tolerance is held to a tight plus 0.000 to minus 0.014 mm band, making it suitable for precision hole location in production and maintenance environments.

This bit is sized at 1.65 mm (0.0650 inches decimal equivalent) and is intended for drilling cast iron and steel in both shop and field applications. With an overall length of 43 mm and a flute length of 20 mm, it fits standard benchtop drill presses, hand drills, and CNC machining centers. The right-hand cutting direction and 5xD flute-to-diameter ratio make it appropriate for shallow to moderate-depth holes. Machinists, tool-and-die technicians, and maintenance mechanics working in metalworking, HVAC fabrication, and general industrial trades will find this size useful for pilot holes, clearance holes, and tap-prep drilling.

Key Features

• M2 high speed steel construction for durability in ferrous workpiece materials including cast iron and steel
• 118-degree standard point angle with web-thinned tapered web for improved penetration and reduced thrust
• Bright uncoated finish suitable for use with standard cutting fluids
• Two-flute regular spiral geometry promotes efficient chip evacuation
• Manufactured to DIN 338 specification with diameter tolerance of plus 0.000 to minus 0.014 mm
• Straight-cylindrical shank at 1.65 mm for compatibility with standard drill chucks and collet holders

Compatibility

Designed as a general-purpose jobber-length drill bit conforming to DIN 338 standards, suitable for use in standard drill chucks and collet systems accepting a 1.65 mm straight-cylindrical shank across drill presses, hand drills, and CNC machining centers.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with rotating tool safety. Secure the shank fully in the chuck or collet before powering the machine, and verify that the workpiece is clamped or fixtured to prevent movement during drilling. Apply appropriate cutting fluid for the workpiece material to extend tool life and maintain hole quality. Never exceed the recommended maximum drilling depth of 17.53 mm for this bit diameter without pecking cycles to clear chips.
