Guhring 9005150051600 Screw Machine Drill Bit 13/64

Product Description

The GUHRING 9005150051600 is a stub-length (screw machine length) twist drill bit designed for high-productivity metal cutting in industrial and trade applications. Built from powdered metal (PM) with a coated finish, this bit measures 0.2031 inches (13/64 inch) in diameter with a 130-degree point angle and a parabolic flute geometry. Overall length is 2.4409 inches, with a flute length of 1.0236 inches. The web-thinned, parallel-web construction reduces entry resistance and improves chip evacuation, making it well suited for drilling cast iron and steel in production environments. Installation and use is handled by machinists, tool-and-die tradespeople, and mechanical contractors working with drill presses, CNC machines, and hand-held power tools.

This drill bit is intended for use in ferrous metal applications, specifically cast iron and steel, at a stub drilling depth up to 0.7190 inches. The screw machine length profile provides added rigidity compared to jobber-length bits, reducing deflection in close-tolerance drilling setups. The 3xD flute-to-diameter ratio supports efficient chip clearing in short-hole applications. It is packaged as a single unit, appropriate for tool-crib stock or individual replacement use in manufacturing and maintenance environments.

Key Features

• 13/64 inch (0.2031 inch) diameter with diameter tolerance of +0.000 to -0.018 mm for consistent hole sizing
• 130-degree split point with web thinning reduces walking and lowers thrust requirements on entry
• Parabolic flute design promotes rapid chip evacuation in cast iron and steel
• Stub/screw machine length (2.4409 inches overall) provides greater rigidity over jobber-length alternatives
• Powdered metal construction with coating extends cutting life in abrasive ferrous materials
• Conforms to DIN 1897 specification for stub-length drill geometry

Compatibility

Designed as an OEM-style replacement or standard stock drill bit for use in drill presses, CNC machining centers, and power hand tools accepting straight-cylindrical shanks. Primary workpiece materials are cast iron and steel per manufacturer specification.

Installation Notes

Secure the straight-cylindrical shank firmly in a keyed or keyless chuck before operation; verify runout is within acceptable limits for the application. Always power down and de-energize the machine before changing bits. Use appropriate cutting fluid or lubrication for steel applications to extend tool life, unless the machining setup specifies dry cutting. Follow applicable shop safety standards and machine manufacturer guidelines when setting spindle speed and feed rate for the workpiece material.
