Guhring 9002050085500 Jobber Drill 8.55 Mm Hss

Product Description

The GUHRING 9002050085500 is a jobber-length twist drill bit designed for general-purpose hole-making in cast iron and steel. Built from M2 high speed steel with an oxide coating, it holds a cutting edge through repeated use in production and maintenance environments. The 118-degree standard point angle suits a wide range of materials without requiring specialized geometry. At 125 mm (4.92 inches) overall length with an 8.55 mm (0.3366 inch) diameter, this drill fits standard drill chucks and CNC toolholders with a straight-cylindrical shank. It is a right-hand cut, two-flute spiral design conforming to DIN 338. Machinists, tool-and-die technicians, and maintenance trades install this drill in manual and CNC drilling operations.

This drill bit is suited for drilling cast iron and steel in both shop and field environments. The regular spiral flute geometry and web-thinned point reduce thrust and improve chip evacuation in through-hole and blind-hole applications. With a 5xD flute-to-diameter ratio and a maximum drilling depth of 68.18 mm (2.68 inches), it handles typical production drilling tasks without extended tooling. It is sold individually and sized within the 8.00 mm to 9.00 mm diameter range, making it a direct replacement when a single bit is needed.

Installation Notes

Install in a clean, properly sized drill chuck or collet and verify runout before cutting. Power down the machine completely before changing tooling. Secure the workpiece to prevent movement during drilling. Follow applicable shop safety standards and manufacturer feed-and-speed recommendations for the specific workpiece material.
