Guhring 9006220019000 Cobalt Jobber Drill Bit 1.9 Mm

Product Description

The GUHRING 9006220019000 is a cobalt jobber length drill bit designed for precision drilling in demanding trade and industrial applications. Built to DIN 338 standards, this bit features a 1.9 mm diameter (0.0748 inches), a 130-degree drill point angle with cone relief geometry, and a parabolic flute design that improves chip evacuation and reduces heat buildup during cutting. The bright, uncoated cobalt construction provides the hardness and thermal resistance needed for consistent performance. It ships individually but carries a minimum order quantity of 10 units, making it suited for shop stocking. Machinists, tool-and-die professionals, and maintenance technicians are the primary installers.

This bit is rated for general-purpose drilling with a primary workpiece material classification of aluminum, as well as K, N, and P material codes covering non-ferrous metals, non-metals, and steel. The straight-cylindrical shank (1.9 mm diameter) fits standard drill chucks without adapters. With an overall length of 46 mm and a flute length of 22 mm, it is sized for compact, close-tolerance work. The maximum drilling depth is 19.15 mm, and the flute-to-diameter ratio is 5xD, supporting controlled penetration in tight setups.

Key Features

• Cobalt construction for elevated hardness and heat resistance versus standard high-speed steel
• 130-degree cone relief point angle reduces thrust force and improves center accuracy on entry
• Parabolic flute geometry promotes efficient chip removal and reduces clogging
• Web-thinned design lowers cutting resistance and extends bit life
• DIN 338 standard compliance ensures dimensional consistency and interchangeability
• Diameter tolerance h8 for precise fit in close-tolerance applications

Compatibility

Designed as an OEM-specification jobber length drill bit conforming to DIN 338, compatible with standard straight-cylindrical chuck systems accepting a 1.9 mm shank. Rated for aluminum and other K, N, and P material classifications per the Series 622 application profile.

Installation Notes

Installation is performed by machinists or maintenance technicians using standard drill press, CNC, or hand-held power drill equipment. Ensure the chuck is fully secured and the workpiece is clamped before operation. No coolant-through capability is present on this bit, so external lubrication or cutting fluid should be applied manually when drilling materials prone to work-hardening. Follow applicable shop safety and machine guarding standards during use.
