Guhring 9006220039700 Cobalt Jobber Drill Bit 5/32 in

Product Description

The GUHRING 9006220039700 is a cobalt jobber length drill bit built for high-performance drilling in demanding applications. Sized at 5/32 inches (0.1562 inches decimal), this bit features a 130-degree drill point angle and a parabolic flute design that promotes efficient chip evacuation and reduced heat buildup. The bright, uncoated finish is standard for cobalt construction and suited for use without coolant. With a 2-flute, right-hand cut geometry and a straight-cylindrical shank, this bit fits standard drill chucks and is rated to a maximum drilling depth of 1.459 inches. It is manufactured to DIN 338 standards and classified as a high-performance grade drill bit.

This drill bit is designed for use on aluminum and similar non-ferrous and general-purpose workpiece materials, indicated by material codes K, N, and P. The parabolic flute geometry and web-thinned, tapered web configuration make it well suited for production drilling environments where chip clearance and hole quality matter. A 5xD flute-to-diameter ratio provides additional reach within standard jobber length parameters. Typical applications include fabrication shops, maintenance and repair operations, and light manufacturing where cobalt tooling is preferred over standard high-speed steel.

Key Features

• Cobalt construction for improved heat and wear resistance compared to standard HSS
• 130-degree drill point angle for reduced thrust and self-centering on entry
• Parabolic flute design promotes fast chip evacuation and reduces clogging
• Web-thinned, tapered web lowers cutting resistance and extends tool life
• Straight-cylindrical shank fits standard drill chucks without adapters
• Manufactured to DIN 338 standard for consistent dimensional accuracy

Compatibility

Designed as an OEM-specification jobber length drill bit conforming to DIN 338, suitable for use in standard drill chucks and drill presses accepting a 5/32-inch straight-cylindrical shank. Primary workpiece materials include aluminum and general non-ferrous and mixed-material applications per material group codes K, N, and P.

Installation Notes

This drill bit is installed by machinists and maintenance technicians in hand drills, drill presses, and CNC drilling equipment. Secure the straight shank fully in the chuck before operation and verify runout before production use. Do not exceed the rated maximum drilling depth of 1.459 inches per pass without retracting to clear chips. No coolant-through capability is present on this bit; use external cutting fluid when drilling materials that generate significant heat.
