Guhring 9005490013200 Jobber Drill Bit No.55 Hss

Product Description

The GUHRING 9005490013200 is a jobber length twist drill bit in wire gauge size No. 55, with a decimal diameter of 0.0520 inches. Built from high speed steel with a bright uncoated finish, it features a parabolic flute geometry and a 130-degree split point designed for fast chip evacuation and accurate hole entry. The web-thinned, tapered web construction reduces thrust during entry. At 1.5 inches overall length with a 0.625-inch flute length, this bit is sized for tight-clearance work. It conforms to DIN 338 standards and is rated as a high-performance grade bit. Licensed tradespeople and machining professionals working with aluminum and similar materials use this bit in production and maintenance drilling applications.

This drill bit is suited for drilling aluminum, non-ferrous metals, and plastics in both production and job-site environments. The parabolic flute profile moves chips away from the cutting zone efficiently, reducing heat buildup and improving hole finish in softer workpiece materials. The straight cylindrical shank is compatible with standard drill chucks and collets. With a maximum drilling depth of 0.552 inches, it is appropriate for shallow-to-mid-depth holes in workpieces where precision and clean entry are required. It is sold individually with a minimum order quantity of 10 units.

Installation Notes

Installation and use of this drill bit is performed by machinists, maintenance technicians, and trade professionals using standard drilling equipment. Secure the shank fully in a properly sized drill chuck or collet before operation. Ensure spindle speed and feed rate are appropriate for the workpiece material to avoid overheating the uncoated HSS cutting edge. Inspect the cutting point for wear or chipping before each use and replace when diameter tolerance or cutting performance degrades.
