Guhring 9006580017000 Cobalt Jobber Drill Bit No. 51

Product Description

The GUHRING 9006580017000 is a cobalt jobber-length drill bit in wire gauge size No. 51, with a decimal diameter of 0.0669 inches. It carries a titanium nitride (TiN) coating and features a parabolic flute geometry designed for faster chip evacuation and reduced heat buildup during drilling. The 130-degree split point with web thinning allows self-centering entry and reduces thrust force on hard ferrous materials. With an overall length of 1-11/16 inches and a flute length of 25/32 inches, this bit meets DIN 338 standards and is classified as a high-performance grade. It is intended for installation and maintenance technicians, machinists, and trade professionals drilling in demanding materials.

This drill bit is rated for use in cast iron and steel workpieces, making it appropriate for structural, mechanical, and fabrication applications where small-diameter precision holes are required. The straight-cylindrical shank fits standard drill chucks without adapters. The 5xD flute-to-diameter ratio and parabolic flute design make it well suited for production drilling and repetitive hole operations where chip packing is a concern. Each package contains one bit, with a minimum order quantity of 10 units per order.

Installation Notes

This bit is installed and used by machinists, HVAC technicians, plumbers, and electricians performing drilling operations on metal components. Secure the workpiece firmly before drilling and confirm chuck grip on the full shank length. Use cutting fluid or coolant where available to extend bit life, particularly in steel. Inspect the cutting edges before each use and replace the bit if chipping or coating wear is observed.
