Guhring 9006220022600 Cobalt Jobber Drill Bit 0.089in

Product Description

The GUHRING 9006220022600 is a cobalt jobber-length drill bit designed for high-performance drilling in a range of workpiece materials. Built to DIN 338 standards, this bit measures 0.089 inches (Wire Size 43) in diameter with an overall length of 2-3/32 inches and a flute length of 1-1/16 inches. The 130-degree split point reduces walking on entry and cuts cleanly without a center punch in many applications. The parabolic flute geometry improves chip evacuation, making it well suited for deeper holes where chip packing is a concern. Machinists, maintenance techs, and fabricators working in production or job-shop environments will recognize the DIN 338 geometry as a reliable, interchangeable standard.

This drill bit is rated for use in aluminum and non-ferrous materials (Material Code K, N, P), though the cobalt substrate gives it added heat resistance compared to standard high-speed steel. It is well suited for hand-held drilling operations, drill presses, and CNC setups requiring a straight-cylindrical shank. The bright uncoated finish keeps tolerances tight and is appropriate for applications where coating buildup or adhesion to soft metals is a concern. The web-thinned, tapered web configuration reduces thrust requirements at the cutting edge, which is especially valuable in smaller-diameter bits like this one.

Key Features

• Cobalt construction for improved heat resistance over standard HSS bits
• 130-degree standard point angle reduces drill walk and cutting force
• Parabolic flute geometry promotes efficient chip evacuation in deep-hole drilling
• Web-thinned tapered web reduces thrust and extends cutting edge life
• Bright uncoated finish prevents material adhesion on aluminum and non-ferrous workpieces
• DIN 338 standard geometry ensures dimensional interchangeability

Compatibility

Designed for use in aluminum and non-ferrous materials (Primary Workpiece Material Codes K, N, P) per DIN 338 specification. Fits any chuck or collet system accepting a straight-cylindrical shank at 0.089 inches diameter.

Installation Notes

This bit is installed by machinists, maintenance technicians, and fabricators using standard drill chucks or collet holders. Secure the straight-cylindrical shank fully in the chuck before operation and verify runout is within acceptable limits, particularly in precision applications. Coolant-through is not supported on this bit; use external cutting fluid or misting as appropriate for the workpiece material. Follow shop safety protocols and applicable machine guarding requirements when operating at speed.
