Guhring 9006180071400 Extra Length Cobalt Drill Bit

Product Description

The GUHRING 9006180071400 is a cobalt, uncoated extra length drill bit engineered for deep hole drilling applications. With a 0.2813 inch diameter (Letter size K), a 6.102 inch flute length, and an 8.858 inch overall length, this bit extends reach well beyond standard jobber-length tooling. The parabolic flute geometry promotes efficient chip evacuation, reducing heat buildup and deflection during extended cuts. A web-thinned, tapered web configuration lowers thrust force at the point, making entry cleaner in tough materials. Manufactured to DIN 1869 specification, this Series 618 bit suits demanding production and maintenance environments where precision and tool life matter.

This drill bit is suited for deep hole drilling in aluminum, titanium alloys, and steel. The 130-degree drill point angle is well-matched to the harder workpiece materials in this range. A straight-cylindrical shank at 9/32 inch diameter seats securely in standard drill chucks and collet holders. The 15xD flute-to-diameter ratio and a maximum drilling depth of 5.681 inches make it appropriate for applications in aerospace, automotive, and general metalworking shops where standard drill lengths fall short. Right-hand cutting direction is conventional for standard spindle setups.

Key Features

• Cobalt tool material for heat resistance in steel and titanium alloy cutting
• Parabolic flute design for improved chip evacuation in deep hole applications
• Web-thinned, tapered web reduces entry thrust and improves point stability
• 130-degree drill point angle optimized for harder and mixed workpiece materials
• DIN 1869 specification ensures dimensional consistency and interchangeability
• 15xD flute-to-diameter ratio with 5.681 inch maximum drilling depth

Compatibility

Designed as a DIN 1869 Series 618 extra length drill bit compatible with standard drill chucks and collet holders accepting a 9/32 inch straight-cylindrical shank. Rated for use in aluminum, titanium alloys, and steel workpieces.

Installation Notes

Installation and use should be performed by a qualified machinist or tooling technician. Before mounting, verify the spindle and chuck are fully stopped and the machine is powered down or e-stopped. Seat the straight-cylindrical shank fully in the chuck or collet to the recommended grip depth to prevent pullout during deep hole cycles. Observe all applicable shop safety procedures and machine manufacturer guidelines when operating at extended reach depths.
