Guhring 9006580019500 Cobalt Jobber Drill Bit 1.95mm

Product Description

The GUHRING 9006580019500 is a cobalt jobber-length drill bit with a titanium nitride (TiN) coating, designed for high-performance drilling in demanding production and maintenance environments. Built to DIN 338 standards, it features a 1.95 mm diameter, a 130-degree split point, and a parabolic flute geometry that promotes efficient chip evacuation and reduced heat buildup. The web-thinned, tapered-web design lowers entry force and improves centering accuracy on cast iron and steel workpieces. With an overall length of 1-15/16 inches and a straight-cylindrical shank, this bit seats securely in standard drill chucks and CNC spindles alike.

This drill bit is suited for production drilling in ferrous metals, particularly cast iron and carbon or alloy steel. Its Series 658 construction makes it a fit for job-shop floors, machining cells, and maintenance departments where consistent hole quality at small diameters is required. The right-hand cut and parabolic flute configuration support both handheld drilling equipment and bench or column drill presses. A maximum drilling depth of 0.83 inches makes it appropriate for through-holes and shallow blind holes in typical workpiece stock.

Key Features

• Cobalt substrate with TiN coating for extended tool life in ferrous materials
• 130-degree split point reduces thrust force and improves self-centering
• Parabolic flute geometry promotes fast chip removal and reduces heat buildup
• Web-thinned, tapered-web design lowers entry resistance at small diameters
• DIN 338 standard compliance ensures dimensional interchangeability
• Straight-cylindrical shank compatible with standard three-jaw and keyless chucks

Compatibility

Designed for drilling cast iron and steel workpieces per primary workpiece material codes K and P. Fits any standard drill chuck or CNC toolholder accepting a 0.0768-inch straight-cylindrical shank.

Installation Notes

Installation and operation should be performed by a qualified machinist or maintenance technician familiar with small-diameter tooling. Secure the shank fully in the chuck and verify runout before starting the cut. Use appropriate cutting fluid or coolant for the workpiece material even though this bit does not have through-coolant capability. Inspect the cutting edges for wear or chipping before each use, as cobalt bits at small diameters are susceptible to breakage if run at incorrect feeds or speeds.
