Guhring 9006180095200 Extra Length Cobalt Drill Bit

Product Description

The GUHRING 9006180095200 is a cobalt extra length drill bit engineered for demanding deep hole drilling applications. It has a 0.375 inch (3/8 inch) diameter with a 130-degree standard point angle and a parabolic flute design that promotes efficient chip evacuation at extended depths. The straight-cylindrical shank measures 3/8 inch in diameter with an 80 mm shank length. Overall length is 10.433 inches, with a flute length of 7.283 inches and a maximum drilling depth of 6.721 inches. This is a Series 618 tool manufactured to DIN 1869 specification. It is intended for use by machinists and tool operators in production and job-shop environments.

This bit is primarily suited for deep hole drilling in aluminum and titanium alloy (material codes K, M, N, P, S), with secondary capability in steel (material code H). The parabolic flute geometry and web-thinned, tapered web configuration reduce thrust force and improve chip flow in long-reach setups where standard length bits are inadequate. The uncoated cobalt construction provides heat resistance without a coating that could reduce effective diameter tolerance. Diameter tolerance is held to +0.000 to -0.022 mm, making it suitable for close-tolerance bores.

Key Features

• Cobalt tool material with uncoated finish for heat resistance and dimensional accuracy
• 130-degree standard point angle with web thinning for reduced entry thrust
• Parabolic flute geometry promotes chip evacuation in deep hole applications
• 10.433 inch OAL and 7.283 inch flute length support a 15xD depth-to-diameter ratio
• Straight-cylindrical 3/8 inch shank for compatibility with standard drill chucks and collets
• Manufactured to DIN 1869 specification with right-hand cutting direction

Compatibility

Designed as a DIN 1869 Series 618 extra length drill bit for deep hole drilling in aluminum, titanium alloy, and steel workpieces. Compatible with any machine spindle or chuck accepting a straight 3/8 inch cylindrical shank.

Installation Notes

This tool is installed and operated by machinists on drill presses, CNC machining centers, or similar equipment. Secure the shank fully in the chuck or collet before operation and verify runout before drilling begins. Because coolant-through is not supported, external coolant or cutting fluid application is recommended when drilling deep holes, particularly in steel. Comply with all applicable machine safety lockout and tagout procedures before changing tooling.
