Guhring 9006520065300 Drill Bit Letter F Hss Tin

Product Description

The GUHRING 9006520065300 is a jobber length drill bit sized at Letter F (0.2571 inches decimal equivalent), designed for high-performance metal removal in demanding trade applications. Built from high speed steel with a titanium nitride (TiN) coating, this bit features a 130-degree split point angle and a parabolic flute geometry that promotes efficient chip evacuation and reduced heat buildup. The straight-cylindrical shank seats securely in standard drill chucks. With a web-thinned, tapered web configuration, the point requires less thrust to start and penetrate material. Licensed machinists, tool and die technicians, and general fabrication professionals will find this bit appropriate for production and maintenance drilling tasks.

This drill bit is rated for primary use in aluminum and non-ferrous materials, consistent with its DIN 338 specification and K, N, and P workpiece material codes. It is suited for residential and commercial fabrication shops, HVAC sheet metal work, plumbing rough-in, and general maintenance environments where a reliable, coated HSS jobber drill is required. The 5xD flute-to-diameter ratio and parabolic flute design make it particularly effective when drilling deeper holes where chip packing is a concern. It ships and is sold individually.

Key Features

• Letter F size — 0.2571 inch decimal equivalent, conforming to DIN 338 standard
• Titanium nitride (TiN) coating extends surface hardness and wear resistance
• 130-degree point angle with web thinning reduces entry thrust and walking
• Parabolic flute geometry (5xD ratio) improves chip flow in deeper holes
• Right-hand cut with straight-cylindrical shank fits standard drill chucks
• High performance grade high speed steel construction for production drilling

Compatibility

Designed for use in aluminum and other non-ferrous materials per DIN 338 specification; compatible with any standard drill chuck accepting a 0.2571 inch straight-cylindrical shank.

Installation Notes

Install in a standard keyed or keyless drill chuck, ensuring the shank is fully seated and secured before operation. Power down and de-energize all equipment before changing bits on electric drills or drill presses. Follow applicable OSHA and shop safety standards for rotating tool use, including proper workpiece fixturing to prevent movement during drilling. Do not exceed the rated maximum drilling depth of 2.095 inches without retracting to clear chips.
