Guhring 9005150075400 Screw Machine Drill Bit

Product Description

The GUHRING 9005150075400 is a stub-length screw machine drill bit designed for high-productivity metal drilling in production and maintenance environments. Built from powdered metal (PMASP60 grade) with a coated finish, this bit measures 0.2969 inches (19/64 inches) in diameter and delivers consistent performance in cast iron and steel. The parabolic flute geometry promotes efficient chip evacuation, while the web-thinned, cone-relief point reduces thrust and improves self-centering at entry. With an overall length of approximately 2.91 inches and a flute length of approximately 1.34 inches, this stub-length format provides added rigidity for accurate hole location in tight setups. Licensed HVAC, plumbing, and mechanical trades rely on stub-length bits where reach is limited and hole straightness matters.

This drill bit is suited for drilling into cast iron and steel in residential and commercial mechanical applications, fabrication shops, and job-site conditions where a short, rigid bit reduces deflection. The 3xD flute-to-diameter ratio and parabolic flute design make it well-matched to CNC drilling centers, drill presses, and hand-held production drills running through ferrous materials. It follows DIN 1897 specification, making it a direct fit where metric-standard tooling is required. The straight-cylindrical shank seats cleanly in standard drill chucks and collet holders without modification.

Key Features

• Powdered metal construction (PMASP60) with coated finish for extended tool life in ferrous materials
• Parabolic flute geometry with web thinning promotes fast chip evacuation and reduced thrust
• 130-degree drill point angle with cone relief improves entry stability in cast iron and steel
• Stub length (DIN 1897) adds rigidity and minimizes deflection in short-reach applications
• Straight-cylindrical shank fits standard chucks and collets without adapters
• Maximum drilling depth of 1.011 inches supports typical through-hole work in production settings

Compatibility

Designed as a DIN 1897 stub-length drill bit for use in standard drill chucks and collet systems; primary workpiece materials are cast iron and steel. No specific machine model compatibility was provided by the manufacturer for this SKU.

Installation Notes

This bit is installed and serviced by machinists, pipefitters, or mechanical contractors using drill presses, CNC machining centers, or hand-held power drills. Secure the straight-cylindrical shank fully in the chuck or collet before operation and verify runout before drilling. Do not exceed the recommended maximum drilling depth of 1.011 inches per pass without retracting to clear chips. Always wear appropriate eye protection and follow applicable OSHA machine-guarding requirements when operating rotary cutting tools.
