Guhring 9055190024400 Cobalt Jobber Drill Bit No. 41

Product Description

The GUHRING 9055190024400 is a cobalt jobber-length drill bit sized to wire gauge No. 41, with a decimal diameter of 0.0960 inches. Built to DIN 338 standards from M35 cobalt steel, the bit carries a titanium nitride (TiN) coating that extends cutting life in abrasive and work-hardening materials. The 118-degree four-facet split point reduces walking at entry and lowers thrust requirements compared to a conventional chisel edge. With an overall length of 57 mm and a spiral flute design, this bit is suited for precision hole-making in production and maintenance environments. Licensed tradespeople and machinists working with light metals, mild steels, and plastics will find this geometry appropriate for close-tolerance through-hole and blind-hole work.

This drill bit is engineered for use in aluminum, mild steel, and plastic workpiece materials, consistent with material codes K, M, N, and P under DIN classification. The 5xD flute-to-diameter ratio and a maximum drilling depth of 26.34 mm make it well-suited for light to moderate depth holes in sheet metal, structural components, and machined parts. The straight-cylindrical shank with a 2.44 mm shank diameter accepts standard drill chucks on benchtop drill presses, CNC machining centers, and handheld drills. The web-thinned, tapered web construction reduces cutting resistance and improves chip evacuation in spiral flute operation.

Key Features

• M35 cobalt steel construction for improved heat and wear resistance over standard high-speed steel
• TiN coating increases surface hardness and reduces friction at the cutting edge
• 118-degree four-facet split point for accurate positioning and reduced entry thrust
• DIN 338 standard jobber length for broad compatibility with standard toolholding
• Web-thinned tapered web improves chip flow and reduces torque demand
• Right-hand spiral flute with regular helix for consistent chip evacuation

Compatibility

Designed as a DIN 338 jobber-length replacement drill bit for applications requiring a No. 41 wire gauge diameter in cobalt tooling; fits any standard drill chuck accepting a 2.44 mm straight-cylindrical shank.

Installation Notes

Installation is performed by licensed machinists or qualified maintenance technicians using a calibrated drill chuck or collet. Secure the shank fully in the chuck before operation and verify runout is within acceptable tolerance before cutting. Apply cutting fluid appropriate to the workpiece material to maximize tool life and surface finish. Do not exceed the rated maximum drilling depth of 26.34 mm in a single pass without retracting to clear chips.
