Guhring 9006220018500 Cobalt Drill Bit 0.0728 in Wire 49

Product Description

The GUHRING 9006220018500 is a cobalt jobber length drill bit engineered for high-performance drilling in metal fabrication, mechanical, and maintenance trade applications. Built to DIN 338 specifications, this bit measures 0.0728 inches in diameter (wire size 49) with a 130-degree split point and a parabolic flute geometry that clears chips efficiently at higher feed rates. The straight-cylindrical shank seats securely in standard drill chucks without modification. It is intended for installation and service technicians, machinists, and trade professionals who require consistent, accurate small-diameter holes in production or field conditions.

This bit is rated for primary use in aluminum, non-ferrous metals, and plastics, corresponding to material codes K, N, and P. The parabolic flute profile supports deeper hole drilling with reduced chip packing compared to standard twist flute designs. The bright, uncoated finish is appropriate for applications where coating buildup tolerance is not a concern and where cutting fluid or oil is used at the point of contact. Right-hand cutting direction is standard for use in conventional drill presses, CNC equipment, and hand-held power drills across light manufacturing and trade service environments.

Key Features

• Cobalt high-performance grade material resists heat and wear during metal drilling
• 130-degree point angle with web-thinned, standard point geometry for fast engagement and reduced thrust
• Parabolic flute profile promotes efficient chip evacuation in deep-hole applications
• Straight-cylindrical shank fits standard drill chucks without adapters
• Built to DIN 338 specification for consistent dimensional accuracy
• Bright uncoated finish suits use with cutting fluid on aluminum and non-ferrous workpieces

Compatibility

Designed as an OEM-specification replacement or production drill bit for use in standard jobber-length drill applications conforming to DIN 338; suitable for aluminum, non-ferrous metals, and plastics as identified by workpiece material codes K, N, and P.

Installation Notes

This bit is installed by machinists and trade professionals using standard drill chucks on drill presses, CNC machines, or hand-held power drills. Ensure the chuck is fully tightened and the workpiece is secured before operation. Use appropriate cutting fluid or coolant at the drill point to extend tool life when drilling metal. Inspect the cutting edges before each use and replace bits showing signs of chipping or dulling to maintain hole quality.
