Guhring 9006580071400 Cobalt Drill Bit Letter K 9/32

Product Description

The GUHRING 9006580071400 is a cobalt jobber length drill bit sized to letter K (9/32 inch, 0.2812 inch decimal), finished with a titanium nitride (TiN) coating for extended tool life. It features a 130-degree split point, a parabolic flute design, and a web-thinned, tapered web configuration that reduces thrust and improves chip evacuation in demanding materials. Conforming to DIN 338, this bit carries a high-performance grade designation and is built for production drilling where tool life and hole quality matter. Licensed machinists, tool-and-die shops, and maintenance mechanics are the primary users.

This drill bit is rated for primary workpiece materials including cast iron and steel (material codes K and P). The parabolic flute geometry and TiN coating make it well suited to high-cycle drilling operations in those materials, whether on a drill press, CNC machining center, or manual mill. The straight-cylindrical shank fits standard drill chucks without adapters. With a 5xD flute-to-diameter ratio, it handles moderate-depth holes in typical jobber applications without requiring extended-length tooling.

Key Features

• Cobalt substrate with titanium nitride (TiN) coating for heat and wear resistance
• 130-degree point angle with web thinning reduces entry force and centers the bit more precisely
• Parabolic flute geometry promotes fast chip evacuation in steel and cast iron
• Tapered web configuration adds rigidity through the cutting zone
• DIN 338 standard geometry ensures consistent fitment with standard toolholders
• Right-hand cut, two-flute design compatible with conventional CNC and manual spindle rotation

Compatibility

Designed for use in cast iron and steel workpieces (ISO material codes K and P) per DIN 338 jobber length specifications. Fits any standard drill chuck accepting a 9/32 inch straight-cylindrical shank.

Installation Notes

Install in a properly sized drill chuck and verify runout before beginning a drilling cycle. Secure the workpiece firmly before engaging the spindle. Follow shop-standard feeds and speeds for cobalt tooling in the target material grade. Do not force the bit through hardened material beyond its rated workpiece material range, as this will prematurely wear the TiN coating and degrade the cutting edge.
