Guhring 9005150015900 Screw Machine Drill Bit 1/16 in

Product Description

The GUHRING 9005150015900 is a stub-length screw machine drill bit designed for high-production drilling in cast iron and steel. Built to DIN 1897 standards, it features a 130-degree split point and a parabolic flute geometry that promotes fast chip evacuation and reduces axial thrust. The powdered metal construction with coating delivers extended tool life in demanding shop and field applications. At 0.0625 inches (1/16 inch) in diameter, this bit is suited for precision small-hole work where rigidity and accuracy are priorities. Licensed machinists and tool-and-die technicians rely on this series for consistent performance in repetitive drilling cycles.

This drill bit is used in screw machine operations, manual drill press setups, and CNC applications where stub length provides added rigidity over standard or jobber-length bits. Its straight-cylindrical shank fits standard drill chucks without adapters. The Series 515 design targets ferrous workpiece materials, specifically cast iron and steel, making it appropriate for metal fabrication shops, production machining environments, and maintenance repair operations requiring repeatable hole quality.

Key Features

• 130-degree drill point angle for reduced thrust and self-centering on ferrous materials
• Parabolic flute design promotes efficient chip evacuation in deep or interrupted cuts
• Powdered metal (PMASP60 grade) construction with coating for extended wear resistance
• Web-thinned parallel web configuration reduces cutting resistance at entry
• Stub length body increases rigidity and reduces deflection in tight setups
• Right-hand cut, straight-cylindrical shank fits standard chucks directly

Compatibility

Designed as a DIN 1897 stub-length screw machine drill bit for use in ferrous workpiece materials including cast iron and steel across standard drill press, screw machine, and CNC drilling applications.

Installation Notes

This bit is installed and operated by machinists, toolroom technicians, and qualified drill press operators. Secure the straight-cylindrical shank fully in a properly sized drill chuck before operation and verify chuck key removal before powering on. Ensure the workpiece is firmly clamped or fixtured to prevent movement during the drilling cycle. Use appropriate cutting fluid or lubrication for the specific workpiece material to extend tool life and maintain hole tolerance.
