Guhring 9055190043700 Cobalt Jobber Drill Bit 11/64

Product Description

The GUHRING 9055190043700 is a cobalt jobber-length drill bit with a titanium nitride (TiN) coating, built to Series 5519 and manufactured to DIN 338 standards. It measures 11/64 inch (0.1719 inch) in diameter with an overall length of 80 mm and a flute length of 47 mm. The M35 cobalt steel construction provides elevated heat resistance compared to standard high-speed steel, making it appropriate for harder or more abrasive materials. The four-facet split point reduces walking on entry and lowers thrust requirements at the start of a cut. Licensed tradespeople and machining professionals use this bit in both hand-held and stationary drilling applications.

This drill bit is suited for use on aluminum, steel, cast iron, and non-ferrous metals, as indicated by workpiece material codes K, M, N, and P. The straight-cylindrical shank fits standard three-jaw chucks without adapters. The regular spiral flute geometry and web-thinned, tapered web design support clean chip evacuation in through-hole and blind-hole applications. It is a practical choice for maintenance, fabrication, and production drilling in residential, commercial, and light industrial settings.
