Guhring 9006180031000 Extra Length Cobalt Drill Bit

Product Description

The GUHRING 9006180031000 is a cobalt extra length drill bit designed for deep hole drilling applications where standard-length drills cannot reach. Built to DIN 1869 specifications, this Series 618 drill features a parabolic flute geometry and a web-thinned, tapered web configuration that promotes chip evacuation and reduces thrust in difficult materials. The 0.122-inch diameter bit has a 130-degree split point and runs right-hand cutting. With an overall length of 6.102 inches and a flute length of 4.134 inches, it delivers a maximum drilling depth of 3.951 inches. This is a professional-grade tool sold in minimum order quantities of 10 units, suitable for shop and field use by machinists and maintenance technicians.

This bit is rated for primary use in aluminum and titanium alloy workpieces, corresponding to material codes K, M, N, P, and S. It also performs in steel as a secondary workpiece material (code H). The straight-cylindrical shank seats in standard drill chucks and collet holders without modification. The 15xD flute-to-diameter ratio makes this an effective choice when drilling deep through-holes in structural components, fixtures, or assemblies where chip packing and heat buildup are common failure points.

Key Features

• Cobalt tool material, uncoated — suited for abrasive and work-hardening alloys
• Parabolic flute design accelerates chip evacuation in deep-hole operations
• 130-degree drill point angle with web thinning reduces entry thrust and walking
• 15xD flute-to-diameter ratio supports drilling depths up to 3.951 inches (100.35 mm)
• Built to DIN 1869 specification for consistent dimensional tolerances
• Diameter tolerance held to +0.000 to -0.018 mm for precision fit applications

Compatibility

Designed as an OEM-specification deep-hole drill per DIN 1869 Series 618, compatible with standard straight-shank drill chucks and collet systems accepting a 0.122-inch shank diameter. Primary workpiece compatibility includes aluminum, titanium alloy, and steel.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with drill press, CNC, or hand-held drilling equipment. Secure the workpiece firmly before drilling and confirm the chuck or collet is properly torqued to the tool holder manufacturer specifications. Use appropriate cutting fluid or coolant for the workpiece material even though this bit does not feature through-coolant capability. Comply with applicable shop safety standards and California Proposition 65 handling requirements as noted in the product specifications.
