Guhring 9006580039700 Cobalt Jobber Drill Bit 5/32 in

Product Description

The GUHRING 9006580039700 is a cobalt jobber-length drill bit with a titanium nitride (TiN) coating, designed for demanding metal drilling applications. Built to DIN 338 standards, it features a 130-degree split point and a parabolic flute geometry that improves chip evacuation and reduces heat buildup during extended drilling cycles. The straight-cylindrical shank measures 5/32 inches in diameter, and the overall length is 2-15/16 inches. Web thinning at the tip reduces thrust requirements when starting holes. This is a high-performance tooling item used primarily by machinists, maintenance technicians, and fabricators working in production or job-shop environments.

This drill bit is rated for use in cast iron and steel workpieces, covering a broad range of ferrous materials common in mechanical, structural, and manufacturing applications. The parabolic flute design supports a flute-to-diameter ratio of 5xD, making it effective in deeper hole applications where chip packing is a concern. The TiN coating extends tool life by hardening the cutting surface and reducing friction against workpiece materials. It is suited for use in both hand-held drill operations and machine setups where consistent hole quality is required in ferrous metals.

Key Features

• Cobalt construction with TiN coating for extended tool life in ferrous materials
• 130-degree point angle with web thinning for reduced entry thrust and accurate starting
• Parabolic flute geometry promotes efficient chip evacuation in deeper holes
• DIN 338 specification ensures dimensional consistency and interchangeability
• Straight-cylindrical shank fits standard drill chucks without adapter
• Right-hand cut with tapered web configuration for balanced cutting performance

Compatibility

Designed as a high-performance OEM-style jobber drill bit for use in standard drill chucks accepting a 5/32-inch straight-cylindrical shank, compatible with benchtop drill presses, CNC drilling machines, and hand drills used in ferrous metal fabrication.

Installation Notes

Installation and use should be performed by machinists or qualified technicians familiar with metal cutting speeds and feeds. Secure the shank fully in the chuck and verify runout before drilling. Do not exceed the recommended maximum drilling depth of 1.459 inches without retracting to clear chips. Use appropriate cutting fluid or coolant for extended production runs to preserve coating and edge life, noting that this bit is not configured for coolant-through delivery.
