Guhring 9055190017800 Cobalt Drill Bit Wire 50

Product Description

The GUHRING 9055190017800 is a cobalt jobber length drill bit in wire size 50 (0.0700 inches diameter), designed for precision drilling in a range of metallic workpiece materials. Built to DIN 338 standards and manufactured from M35 cobalt high-speed steel, this bit carries a Titanium Nitride (TiN) coating that extends tool life and reduces cutting friction. It features a 118-degree four-facet split point for accurate self-starting entry without center punching, a regular spiral flute with web thinning for improved chip evacuation, and a straight-cylindrical shank for secure chuck retention. Licensed electricians, machinists, and field service technicians working in sheet metal, structural steel, or aluminum fabrication rely on this bit for consistent, repeatable hole quality.

This drill bit is suited for light-duty precision drilling applications in aluminum, mild steel, stainless steel, and cast materials, corresponding to material codes K, M, N, and P. Its jobber length profile makes it a practical choice for general-purpose drill press, hand drill, and CNC drilling operations where a compact flute-to-shank ratio is required. The 5xD flute-by-diameter ratio and 19.33 mm maximum drilling depth make it appropriate for shallow-to-moderate depth holes in thin stock and sheet goods. It is sold individually and subject to a minimum order quantity of 10 pieces.

Key Features

• M35 cobalt steel construction for heat resistance and durability in hard materials
• TiN coating reduces friction and extends cutting edge life
• 118-degree four-facet split point promotes accurate entry and reduces walking
• Web-thinned tapered web improves chip flow and reduces thrust force
• Right-hand cut with regular spiral flute; 2-flute configuration
• Manufactured to DIN 338 specification for dimensional consistency

Compatibility

Designed as a general-purpose jobber length drill bit compatible with any standard drill chuck accepting a 1.78 mm straight-cylindrical shank. Suitable for drilling aluminum, mild steel, stainless, and cast materials per material codes K, M, N, and P.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with drilling operations on the target workpiece material. Secure the shank fully in a properly sized drill chuck before operation and verify spindle speed is appropriate for the workpiece material and bit diameter. Coolant-through is not supported on this bit; use external cutting fluid or cutting oil when drilling ferrous materials to manage heat buildup. Inspect the cutting edges before each use and replace any bit showing chipping, discoloration from overheating, or diameter wear outside the stated tolerance of +0.000 to -0.014 mm.
