Guhring 9006220021000 Cobalt Jobber Drill Bit 2.1 Mm

Product Description

The GUHRING 9006220021000 is a cobalt jobber-length drill bit designed for high-performance drilling in a range of workpiece materials. Built to DIN 338 standards, this bit features a 2.1 mm diameter, a 130-degree drill point angle, and a parabolic flute design that promotes efficient chip evacuation and reduced heat buildup during operation. The bright, uncoated finish and cobalt construction make it well-suited for demanding applications where standard high-speed steel bits fall short. With an overall length of 1-15/16 inches and a straight-cylindrical shank, it mounts readily in standard drill chucks and CNC toolholders. This bit ships individually and carries a minimum order quantity of 10 units.

This drill bit is rated primarily for aluminum and similar non-ferrous and general-purpose workpiece materials, reflected in its K, N, and P material group designations. It is a strong choice for machinists, tool-and-die technicians, and maintenance professionals who need a reliable small-diameter bit for production drilling, fixture work, or precision hole-making. The parabolic flute geometry and web-thinned point help maintain accuracy and reduce thrust in thin-wall or stacked-material setups common in light manufacturing and fabrication environments.

Key Features

• Cobalt construction with bright uncoated finish for high-performance drilling
• 130-degree standard point angle for positive engagement and reduced walking
• Parabolic flute geometry for efficient chip removal and cooler cutting
• Web-thinned, tapered web for reduced axial thrust at entry
• Straight-cylindrical shank compatible with standard drill chucks and collets
• Manufactured to DIN 338 specification for consistent dimensional tolerances

Compatibility

Designed as a DIN 338 jobber-length drill bit suitable for use in standard drill chucks, CNC machining centers, and benchtop drill presses accepting straight-cylindrical shanks in the 0.0827 decimal inch diameter range. Rated for aluminum and general-purpose workpiece materials per K, N, and P material group classifications.

Installation Notes

This bit is installed and serviced by machinists, tool-and-die technicians, and maintenance professionals using standard toolholding equipment. Ensure the chuck or collet is fully secured before operation and confirm spindle speed is appropriate for the material and diameter being drilled. Inspect the cutting edge for wear or chipping before each use, as small-diameter cobalt bits are susceptible to breakage under side-load or improper feed rates. Follow applicable shop safety procedures and machine manufacturer guidelines during tool changes.
