Guhring 9005020095200 Extra Length Drill Bit 0.375 in Hss

Product Description

The GUHRING 9005020095200 is a high-speed steel extra length drill bit engineered for deep hole drilling applications. Built to DIN 1869 standards, it features a parabolic flute design and a web-thinned, tapered web configuration that improves chip evacuation and reduces cutting forces in long-reach operations. The bit carries a 130-degree point angle and measures 10.433 inches in overall length, with a 7.283-inch flute length and a 15xD flute-to-diameter ratio. It is uncoated and has no coolant-through capability. Licensed HVAC techs, machinists, and maintenance professionals working in production or job-shop environments install this bit in standard drill chucks or milling setups requiring extended reach.

This drill bit is intended for deep hole drilling into aluminum and similar non-ferrous and soft metallic workpiece materials, as indicated by its K, N, and P material code designations. The parabolic flute geometry aids chip flow at extended depths where conventional flutes tend to pack and bind. The Series 502 classification designates it as a high-performance grade tool suited to production environments where consistent hole quality and tool life are required. It ships as a single-piece unit and has a minimum order quantity of one.

Key Features

• High-speed steel construction, uncoated, for use in aluminum and compatible soft-metal workpieces
• Parabolic flute geometry with web thinning and tapered web for improved chip evacuation in deep holes
• 130-degree standard point angle for accurate entry and reduced thrust
• 10.433-inch overall length with a 7.283-inch flute length supporting a 15xD depth-to-diameter reach
• Maximum drilling depth of 6.721 inches (170.72 mm)
• Straight-cylindrical shank at 3/8 inch diameter fits standard drill chucks without adapters
• Conforms to DIN 1869 specification for extra-length twist drills

Compatibility

Designed as an OEM-style extra length drill bit compatible with standard 3/8-inch straight-shank drill chucks; primary workpiece material designation covers aluminum and similar non-ferrous and soft metallic materials per K, N, and P material codes.

Installation Notes

Installation is performed by qualified machinists or maintenance technicians using compatible drill presses, CNC machining centers, or hand drills with 3/8-inch chuck capacity. Secure the shank fully in the chuck and verify runout before engaging the workpiece, as extra-length bits are more sensitive to misalignment than standard-length tooling. Reduce feed rates compared to standard-length equivalents to prevent deflection and premature tool wear during deep hole operations. Follow applicable shop safety protocols and machine manufacturer guidelines when operating at extended reach.
