Guhring 9006180100000 Extra Length Cobalt Drill Bit

Product Description

The GUHRING 9006180100000 is a Series 618 extra length cobalt drill bit engineered for deep hole drilling applications in demanding materials. The bit measures 0.3937 inches in diameter with a 130-degree drill point angle, a parabolic flute design, and a total overall length of 10.433 inches. The flute length runs 7.283 inches, supporting a maximum drilling depth of 6.693 inches. Constructed from high-performance cobalt and left uncoated, this bit is built for work in aluminum, titanium alloy, and steel. Right-hand cutting direction. A web-thinned, tapered web configuration reduces thrust and improves chip flow in deep-hole work. Installed by machinists and tool and die professionals on CNC and manual drill setups.

This drill bit is suited for deep hole drilling in both light-alloy and ferrous materials, including aluminum, titanium alloy, and steel. The 15xD flute-to-diameter ratio makes it appropriate for applications where standard-length bits cannot reach. The straight-cylindrical shank allows mounting in standard drill chucks and collet holders without special adapters. Two flutes promote efficient chip evacuation over extended drilling depths. Typical applications include structural component machining, fixture fabrication, and production drilling where reach and hole quality are both critical.

Key Features

• Parabolic flute geometry promotes chip flow and reduces heat buildup in deep holes
• 130-degree drill point angle optimized for work in aluminum, titanium alloy, and steel
• Web-thinned tapered web reduces axial thrust and improves penetration
• 15xD flute-to-diameter ratio supports drilling depths up to 6.693 inches
• Straight-cylindrical shank fits standard drill chucks and collet holders
• No coolant-through required; suitable for conventional flood or mist coolant setups

Compatibility

Designed as a DIN 1869-specification extra length drill bit suitable for use with standard drill chucks and collet systems accepting a 0.3937-inch straight-cylindrical shank. Primary workpiece materials are aluminum and titanium alloy; secondary workpiece material is steel.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom professionals. Secure the shank fully in the chuck or collet before operation and verify runout before drilling. Ensure the machine spindle and workpiece are properly fixtured to prevent deflection over the extended length. Follow applicable shop safety standards and machine tool manufacturer guidelines when selecting feeds, speeds, and coolant delivery for the workpiece material.
