Guhring 9005150014000 Stub Drill Bit 0.055 in Powdered Metal

Product Description

The GUHRING 9005150014000 is a screw machine length (stub) drill bit engineered for precision drilling in ferrous materials. It measures 0.055 inches in diameter with an overall length of 1.2598 inches and a flute length of 0.3543 inches. Built to DIN 1897 standards, this bit is manufactured from powdered metal (PMASP60 grade) with a coated finish for improved wear resistance. The 130-degree point angle and parabolic flute geometry promote efficient chip evacuation and reduced heat buildup. It features a straight-cylindrical shank, web-thinned tip, and parallel web configuration. Typically installed by machinists, toolroom technicians, and maintenance professionals working on precision metal components.

This drill bit is designed for use in cast iron and steel workpieces. The stub length makes it well suited for drilling in confined spaces or on short-travel drill press setups where rigidity and accuracy are priorities. The 3xD flute-to-diameter ratio and maximum drilling depth of 0.2720 inches support controlled, repeatable results in production and maintenance environments alike. It is sold as a single unit and is appropriate for use in CNC machines, drill presses, and hand-held precision drilling equipment with compatible collet or chuck systems.

Key Features

• Powdered metal construction (PMASP60 grade) with coated finish for extended tool life
• 130-degree point angle for self-centering entry on cast iron and steel
• Parabolic flute geometry for efficient chip evacuation in deep-hole drilling
• Web-thinned tip reduces thrust force and improves penetration
• Stub length design increases rigidity and reduces deflection
• Manufactured to DIN 1897 specification for consistent dimensional accuracy

Compatibility

Designed as an OEM-style replacement or direct-use drill bit for applications in cast iron and steel. Compatible with standard straight-shank drill chucks and collet systems sized for a 0.055 inch diameter shank.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom technicians familiar with small-diameter drill bit handling. Secure the bit firmly in a compatible chuck or collet before operation, and verify runout is within acceptable tolerance to avoid bit breakage at this diameter. Power down all equipment completely before changing tooling. At 0.055 inches diameter, avoid side-loading or excessive feed pressure, as small-diameter bits are susceptible to breakage under lateral stress.
