Guhring 9006220025500 Jobber Drill Bit 2.55mm Cobalt

Product Description

The GUHRING 9006220025500 is a cobalt jobber length drill bit designed for high-performance drilling in metalworking and fabrication applications. Built to DIN 338 standards, this bit features a 2.55 mm (0.1004 inch) diameter with a parabolic flute geometry that promotes efficient chip evacuation and reduces heat buildup during cutting. The 130-degree split point allows the bit to self-center on entry, minimizing walking on hard or slick surfaces. With an overall length of 57 mm (2.25 inches) and a flute length of 30 mm (1.1875 inches), this is a standard jobber-length tool suited for general-purpose close-tolerance drilling. It is installed by machinists, tool and die makers, and maintenance technicians working with drill presses, CNC equipment, or hand-held power tools.

This drill bit is primarily intended for drilling aluminum and non-ferrous metals, as indicated by the Primary Workpiece Material Code K, N, and P classifications. It performs well in production environments where consistent hole quality and dimensional accuracy are required. The bright uncoated finish suits applications where coating interaction with workpiece material is a concern, and the web-thinned tapered web reduces thrust load during entry. The straight-cylindrical shank fits standard drill chucks without adapters, making it compatible with a wide range of machine spindles and portable tools.

Key Features

• Cobalt high-speed steel construction for heat and wear resistance in metalworking
• 130-degree standard point angle with web thinning for self-centering and reduced thrust
• Parabolic flute profile improves chip flow and reduces clogging at depth
• DIN 338 specification ensures dimensional consistency and interchangeability
• Bright uncoated finish suited for aluminum and non-ferrous workpiece materials
• Straight-cylindrical shank fits standard chucks without adapters

Compatibility

Designed as an OEM-style replacement or direct-use jobber length drill bit for applications conforming to DIN 338 standards, suitable for use in drill presses, CNC machining centers, and portable power tools accepting a 0.1004-inch straight shank.

Installation Notes

This bit is installed by machinists or maintenance technicians in any drill chuck or collet accepting a 0.1004-inch straight shank. Before changing bits, power down and de-energize the machine tool per standard lockout/tagout procedures. Ensure the chuck or collet is clean and free of debris before seating the shank. Do not exceed the recommended maximum drilling depth of 26.18 mm (1.031 inches) in a single pass without pecking to clear chips.
