Guhring 9055210016000 Screw Machine Drill Bit 0.063 in

Product Description

The GUHRING 9055210016000 is a stub-length screw machine drill bit designed for high-performance drilling in demanding applications. Built from powdered metal with a coated finish, this bit features a parabolic flute geometry and a 130-degree drill point angle that promotes efficient chip evacuation and reduced thrust. The straight-cylindrical shank measures 1.60 mm in diameter, and the overall length is approximately 1.34 inches (34 mm). With a web-thinned point and cone relief tip, this bit is engineered for precision entry and clean hole formation. It is installed by machinists, tool-and-die professionals, and maintenance technicians working with high-strength materials.

This drill bit is rated for primary use in titanium alloy workpieces, making it suitable for aerospace, medical, and precision manufacturing environments where material hardness and work-hardening are concerns. The 3xD flute-to-diameter ratio and parabolic flute form support deep chip clearance relative to the stub length. The bit conforms to DIN 1897 standards and carries a diameter tolerance of h8, making it appropriate for close-tolerance hole applications. It is sold individually and requires a minimum order of 10 units.

Key Features

• 130-degree drill point angle for reduced thrust and improved centering on hard alloys
• Parabolic flute design promotes rapid chip evacuation in deep drilling relative to stub length
• Web-thinned cone relief point reduces cutting force at entry
• Powdered metal construction with coating for extended tool life in abrasive materials
• Conforms to DIN 1897 stub-length standard with h8 diameter tolerance
• No coolant-through design simplifies setup on standard drill presses and machining centers

Compatibility

Designed as an OEM-style stub-length screw machine drill bit per DIN 1897, suitable for use in standard straight-shank drill chucks and collet holders accepting 1.60 mm shank diameters.

Installation Notes

This bit is installed by machinists and precision metalworking professionals using standard drill presses, CNC machining centers, or hand-held drilling equipment with an appropriate chuck or collet. Secure the workpiece and verify spindle runout before drilling titanium or other work-hardening alloys. Use appropriate cutting fluid or lubricant for the workpiece material even though this bit does not feature internal coolant delivery. Inspect the cutting edges before each use and replace at first sign of edge wear to maintain hole tolerance.
