Guhring 9006180032000 Extra Length Cobalt Drill Bit

Product Description

The GUHRING 9006180032000 is a Series 618 extra length cobalt drill bit designed for deep hole drilling in demanding production and fabrication environments. With a 0.126 inch diameter and a 6.102 inch overall length, this bit reaches depths that standard-length drills cannot. The parabolic flute geometry promotes efficient chip evacuation, reducing the risk of packing and bit deflection during long-reach cuts. The 130-degree split point with web thinning allows for fast penetration with minimal walking on entry. This bit is installed by machinists, tool-and-die technicians, and CNC operators working in metalworking and manufacturing settings.

This drill bit is rated for use in aluminum, titanium alloy, steel, and other materials across ISO material codes K, M, N, P, and S as primary workpiece materials, with steel (code H) as a secondary application. The 15xD flute-to-diameter ratio and 4.134 inch flute length support drilling depths up to 3.945 inches in a single pass without peck cycling in favorable conditions. It is suited for aerospace component work, structural fabrication, and precision machining where extended reach and hole quality are critical.

Key Features

• Cobalt tool material for heat resistance and durability in hard and abrasive workpiece materials
• Parabolic flute design promotes chip flow in deep hole applications up to 3.945 inches depth
• 130-degree drill point angle with web thinning reduces thrust force and improves self-centering
• Uncoated finish maintains tight diameter tolerance of +0.000 to -0.018 mm for close-tolerance holes
• Straight-cylindrical shank with 0.126 inch diameter fits standard drill chucks and collet systems
• Conforms to DIN 1869 specification for extra length drills

Compatibility

Designed as an OEM-style Series 618 DIN 1869 extra length drill bit for use in CNC machining centers, drill presses, and manual machines equipped with standard straight-shank toolholders accepting a 0.126 inch shank diameter.

Installation Notes

This bit is installed by machinists and CNC operators following standard toolholding procedures. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully and evenly in the chuck or collet to the recommended engagement depth to prevent runout. Observe applicable shop safety and cutting fluid protocols when drilling titanium alloy or hardened steel materials.
