Guhring 9006220024900 Cobalt Jobber Drill Bit 0.098 in

Product Description

The GUHRING 9006220024900 is a cobalt jobber-length drill bit built for high-performance drilling in a wide range of materials. Sized at 0.098 inches in diameter (wire size 40), it features a 130-degree drill point angle and a parabolic flute design that promotes efficient chip evacuation and reduced heat buildup. The bright, uncoated cobalt construction provides inherent heat and wear resistance without a surface coating. With an overall length of 2.25 inches and a flute length of 1.1875 inches, this bit is well suited to standard jobber-length drilling applications. It is installed and used by machinists, maintenance technicians, HVAC fabricators, and metal tradespeople working in production or field environments.

This drill bit is designed primarily for drilling aluminum and similar nonferrous and ferrous materials, as indicated by its workpiece material codes K, N, and P. The parabolic flute geometry is particularly effective in soft to medium-hardness materials where chip packing is a common issue. The straight-cylindrical shank fits standard three-jaw drill chucks on both bench-top and handheld equipment. Its compact jobber length makes it practical in space-constrained setups while maintaining adequate flute capacity for typical hole depths encountered in trade and light manufacturing work.

Key Features

• 0.098-inch (wire size 40) diameter cobalt construction for durability in demanding applications
• 130-degree drill point angle suited to a broad range of material types
• Parabolic flute geometry promotes efficient chip removal and reduces heat buildup
• Bright, uncoated finish on cobalt substrate provides natural heat and wear resistance
• Right-hand cut with web-thinned, tapered web for reduced thrust and cleaner entry
• Meets DIN 338 specification for jobber-length drill bits

Compatibility

Designed as an OEM-specification replacement or direct-use jobber drill bit conforming to DIN 338 standards, compatible with standard straight-cylindrical chuck equipment used in drilling aluminum and similar workpiece materials classified under material codes K, N, and P.

Installation Notes

This bit is installed by machinists and trade technicians using standard three-jaw chuck equipment; ensure the chuck is properly tightened and the bit is fully seated before operation. Always power down and lock out the drill press or handheld tool before changing bits. Use appropriate cutting fluid or air blast when drilling metals to extend bit life and maintain dimensional accuracy. Follow applicable shop safety standards and manufacturer equipment guidelines during use.
