Guhring 9055190020600 Cobalt Jobber Drill Bit 0.0810 in

Product Description

The GUHRING 9055190020600 is a cobalt jobber-length drill bit sized to 0.0810 inches (wire size No. 46) and finished with a titanium nitride (TiN) coating for improved wear resistance and heat tolerance. Built to DIN 338 standards and manufactured from M35 cobalt steel, it features a 118-degree, 4-facet split point that reduces walking and improves penetration in hard materials. With an overall length of 1.9291 inches and a 0.9449-inch flute length, this bit is suited for precision drilling in tight spaces. It is designed for right-hand cutting with a regular spiral flute and a straight shank. Licensed HVAC, mechanical, and fabrication tradespeople working with ferrous and non-ferrous metals rely on this bit for consistent performance in production and maintenance environments.

This drill bit is intended for use in steel, stainless steel, and cast iron applications. The web-thinned, tapered web construction reduces thrust requirements when drilling harder alloys. Its 5xD flute-to-diameter ratio supports chip evacuation during moderate-depth holes. The bit is a general-purpose grade suitable for both hand-held drill applications and drill press or CNC operations where a straight-shank jobber bit is the specified tool. Maximum drilling depth is 0.8230 inches.

Key Features

• Cobalt M35 construction for elevated heat and wear resistance in hard-metal drilling
• TiN coating extends tool life and reduces friction during cutting
• 118-degree, 4-facet split point minimizes walking and improves hole entry accuracy
• Web-thinned, tapered web reduces axial thrust in stainless steel and cast iron
• Right-hand cut with regular spiral flute for efficient chip removal
• Manufactured to DIN 338 specification for consistent dimensional tolerances

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard straight-shank drill chuck rated for 0.0810-inch diameter tooling. Suitable for use in drill presses, hand drills, and CNC drilling operations. Primary workpiece materials include steel, stainless steel, and cast iron per material codes K, M, N, and P.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists, tooling technicians, or trade professionals familiar with cutting tool selection and drill press or hand-tool operation. Secure the straight shank firmly in a properly sized chuck before operation, and verify chuck runout is within acceptable limits to maintain the stated diameter tolerance of +0.000 to -0.014 mm. Power down and de-energize any machine tool before changing or inspecting tooling. Do not exceed the maximum drilling depth of 0.8230 inches in a single pass without retracting to clear chips.
