Guhring 9006220042200 Cobalt Jobber Drill Bit 0.1661 in

Product Description

The GUHRING 9006220042200 is a cobalt jobber length drill bit sized at 0.1661 inches in diameter, equivalent to a wire gauge number 19. Built to DIN 338 standards, it features a 130-degree split point and a parabolic flute geometry that improves chip evacuation and reduces heat buildup during drilling. The straight-cylindrical shank fits standard drill chucks without modification. This is a high-performance grade tool intended for production and maintenance trades that require consistent, accurate hole sizing in non-ferrous and ferrous workpiece materials.

This drill bit is rated for primary use in aluminum and similar non-ferrous materials, as indicated by the K, N, and P workpiece material codes. It is well suited for sheet metal shops, mechanical contractors, fabrication facilities, and maintenance technicians who drill repetitive holes in aluminum extrusions, plate, and structural members. The parabolic flute design makes it particularly effective in applications where chip packing is a concern, such as deep holes or high-feed drilling cycles. It is sold individually and is appropriate for both hand-held drill motors and drill press setups.

Key Features

• Cobalt construction with bright uncoated finish for high-temperature drilling performance
• 130-degree point angle with web-thinned, tapered web for reduced thrust and easier starting
• Parabolic flute geometry promotes efficient chip removal and reduces clogging
• Right-hand cut, straight-cylindrical shank compatible with standard drill chucks
• Manufactured to DIN 338 specification for consistent dimensional tolerances
• Diameter tolerance of -0.018 to 0.000 mm ensures accurate, repeatable hole sizing

Compatibility

Designed as a DIN 338-compliant jobber length drill bit suitable for use in standard keyed and keyless drill chucks accepting straight-cylindrical shanks in the 0.1500 to 0.2000 inch diameter range.

Installation Notes

This drill bit is installed and operated by machinists, fabricators, and maintenance technicians using drill presses, CNC drilling machines, or hand-held electric drills. Secure the shank fully in the chuck before operation and confirm the workpiece is clamped or fixtured to prevent movement. Use appropriate cutting fluid or coolant when drilling in production settings to extend tool life, noting that this bit does not support internal coolant-through delivery. Inspect the cutting edges for wear before each use and replace the bit if chipping or dulling is observed.
