Guhring 9006580111100 Cobalt Jobber Drill Bit 7/16 in

Product Description

The GUHRING 9006580111100 is a cobalt jobber-length drill bit engineered for demanding metal drilling applications. Built to DIN 338 standards, this high-performance bit features a titanium nitride (TiN) coating over a cobalt steel substrate, combining surface hardness with the heat resistance needed for interrupted cuts and abrasive materials. The 130-degree split point reduces walking on entry and lowers thrust requirements. At 5-19/32 inches overall length with a 3-11/16-inch flute, it fits standard drill chucks and drill presses without extended-reach tooling. Machinists, maintenance mechanics, and fabricators working with cast iron and steel will find this bit suited to production-rate use.

This bit is rated for primary use in cast iron and steel (ISO material codes K and P). It performs in hand-held drill applications, drill press work, and light CNC operations where a straight-cylindrical shank is appropriate. The parabolic flute geometry improves chip evacuation at higher feed rates, reducing heat buildup in the cut zone. The 5xD flute-to-diameter ratio and web-thinned, tapered web configuration support deeper hole entry before chip packing becomes a concern. Maximum rated drilling depth is 3.045 inches.

Key Features

• Cobalt steel construction with TiN coating for extended tool life in ferrous materials
• 130-degree standard point angle with web thinning reduces entry thrust and centering error
• Parabolic flute design promotes efficient chip evacuation at higher feed rates
• Straight-cylindrical shank at 7/16 inches fits standard chucks without adapters
• Manufactured to DIN 338 specification for consistent dimensional tolerances
• Right-hand cut, two-flute configuration standard for general-purpose metal drilling

Compatibility

Designed for use in cast iron and steel workpieces. Compatible with any drill press, hand drill, or light CNC spindle accepting a 7/16-inch straight-cylindrical shank. Conforms to DIN 338 jobber-length standards.

Installation Notes

Secure the shank fully in the chuck and verify runout before drilling. Use appropriate cutting fluid or coolant for steel applications to preserve coating life, noting that coolant-through is not available on this bit. Allow the point geometry to self-center before applying full feed pressure. Inspect the cutting edges and TiN coating condition periodically; re-sharpening will remove the coating at the tip and should be performed by qualified tool grinders.
