Guhring 9006220028200 Cobalt Jobber Drill Bit 0.111 in

Product Description

The GUHRING 9006220028200 is a cobalt jobber length drill bit designed for high-performance drilling in demanding shop and field applications. Built to DIN 338 standards, it features a 0.111-inch diameter with a 130-degree standard point angle and a parabolic flute geometry that clears chips efficiently and reduces heat buildup. The straight-cylindrical shank seats securely in standard chucks. The bright, uncoated finish suits applications where coating interaction with workpiece material is a concern. This bit is intended for use by machinists, fabricators, and trade professionals who require consistent, repeatable hole quality in production or maintenance environments.

The 9006220028200 is engineered for drilling aluminum and similar non-ferrous and soft workpiece materials, as indicated by its primary workpiece material codes (K, N, P). The parabolic flute design promotes fast chip evacuation, making it well suited for deeper holes where chip packing is a common problem. With an overall length of 2-13/32 inches and a flute length of 1-5/16 inches, it fits standard benchtop drill presses and handheld drill drivers alike. Right-hand cut configuration is compatible with conventional clockwise-rotating spindles.

Key Features

• Cobalt construction provides superior heat resistance and edge retention compared to standard high-speed steel
• 130-degree standard point angle reduces walking and improves centering on entry
• Parabolic flute geometry accelerates chip removal and reduces heat in the cut zone
• Web-thinned, tapered web configuration lowers thrust requirements and eases penetration
• Bright uncoated finish suitable for aluminum and non-ferrous workpiece materials
• Conforms to DIN 338 specification for consistent dimensional accuracy

Compatibility

Designed as an OEM-specification jobber length drill bit per DIN 338, suitable for use in standard straight-shank drill chucks on benchtop drill presses, CNC drilling machines, and handheld drill drivers that accept straight-cylindrical shanks.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with rotating cutting tools. Ensure the drill chuck is fully tightened and the workpiece is securely clamped before beginning any drilling operation. Disconnect or de-energize the drill press or power tool before changing bits. Do not exceed the recommended speed range for the workpiece material and bit diameter, and never force a dull bit — replace or resharpen before continuing.
