Guhring 9006180065000 Extra Length Cobalt Drill Bit

Product Description

The GUHRING 9006180065000 is a cobalt, extra length drill bit engineered for deep hole drilling applications in metal fabrication and machining environments. Built to DIN 1869 standards, this Series 618 bit features a parabolic flute geometry and a web-thinned, tapered web configuration that improves chip evacuation and reduces thrust at depth. The 130-degree drill point angle and right-hand cutting direction make it well suited for productive material removal in demanding setups. At 8.465 inches overall length with a 5.906-inch flute length, the bit reaches depths that standard-length drills cannot. This tool is installed and used by machinists, tool and die professionals, and CNC operators.

This drill bit is designed for use in deep hole drilling operations where reach and chip flow are critical concerns. Primary workpiece materials include aluminum, titanium alloy, and steel. Its parabolic flute profile promotes efficient chip removal in these materials, reducing the need for peck drilling cycles. The straight-cylindrical shank fits standard drill chucks and collet holders without modification. Typical applications include aerospace component work, structural fabrication, and precision machining in job shop or production environments requiring extended reach beyond standard drill lengths.

Key Features

• Cobalt tool material provides heat resistance and edge retention in hard and abrasive workpiece materials
• Parabolic flute design promotes rapid chip evacuation in deep hole applications
• 130-degree drill point angle optimized for entry performance and reduced thrust
• Web-thinned, tapered web configuration lowers cutting forces at depth
• Straight-cylindrical shank is compatible with standard chucks and collet systems
• Flute-to-diameter ratio of 15xD supports drilling depths up to 5.522 inches (140.25 mm)
• Uncoated finish allows easy regrinding and inspection

Compatibility

Designed as an OEM-style extra length drill bit conforming to DIN 1869 specifications, suitable for use with standard drill chucks and collet holders accepting a 0.2559-inch straight-cylindrical shank. Primary workpiece materials are aluminum, titanium alloy, and steel per material codes K, M, N, P, S, and H.

Installation Notes

This bit is intended for use by trained machinists in drill press, milling machine, or CNC machining center setups. Secure the shank fully in the chuck or collet and verify runout before beginning a cut. Power down and lock out the machine before changing tooling. Do not exceed the maximum drilling depth of 5.522 inches without re-evaluating setup rigidity and chip clearance.
