Guhring 9005300076000 Jobber Drill Bit 0.2992in Firex Pm

Product Description

The GUHRING 9005300076000 is a jobber length drill bit engineered for high-performance drilling in ferrous materials. Built from PM-ASP-60 powdered metal (PM) and finished with a FIREX coating, this bit is designed to outlast standard HSS tooling in demanding production and maintenance environments. It features a 130-degree point angle with cone relief and a parabolic flute geometry that improves chip evacuation and reduces heat buildup at the cutting edge. The straight-cylindrical shank measures 0.2992 inches in diameter, making it compatible with standard drill chucks and collet holders. Overall length is 4-19/32 inches. This bit is sold individually and is appropriate for machine tool operators, maintenance machinists, and fabrication shops.

This drill bit is designed for use in cast iron and steel workpieces, corresponding to ISO material groups K and P. The parabolic flute with a 5xD flute-to-diameter ratio supports deeper hole applications with improved swarf clearance. Maximum drilling depth reaches 2.504 inches (63.60 mm). The web-thinned, tapered web configuration reduces thrust force at the point entry, making it suitable for CNC machining centers, drill presses, and hand-held power tools used in structured production workflows. It conforms to DIN 338 standards, which govern jobber length geometry and dimensional tolerances.

Key Features

• PM-ASP-60 powdered metal construction for extended tool life in ferrous applications
• FIREX coating reduces friction and improves wear resistance at elevated cutting temperatures
• 130-degree cone relief point angle optimized for cast iron and steel entry
• Parabolic flute with web thinning improves chip flow and lowers thrust requirements
• DIN 338 standard geometry ensures dimensional consistency and drop-in compatibility with standard toolholders
• Right-hand cut with straight-cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as a DIN 338 jobber length drill bit for use in cast iron and steel (ISO material groups K and P). Fits any standard drill chuck or collet accepting a 0.2992-inch straight-cylindrical shank.

Installation Notes

Install in a drill chuck or collet holder rated for the shank diameter before powering the machine. Secure the workpiece firmly before drilling to prevent movement. No coolant-through capability is present on this bit, so external cutting fluid or mist cooling is recommended when drilling deeper holes in steel. Follow shop safety procedures and applicable OSHA machine guarding requirements when operating drilling equipment.
