Guhring 9006220107200 Cobalt Drill Bit 27/64 in

Product Description

The GUHRING 9006220107200 is a cobalt jobber length drill bit designed for high-performance drilling in demanding materials. Built to DIN 338 standards, this bit features a 27/64 inch (0.4200 inch) diameter with a 130-degree split point and a parabolic flute geometry. The parabolic flute design promotes faster chip evacuation and reduces heat buildup during extended drilling cycles. The web-thinned, tapered web configuration lowers entry resistance, making it well suited for production environments where consistent hole quality matters. A straight-cylindrical shank ensures secure, repeatable chuck engagement. Licensed HVAC techs, machinists, and general trade professionals working with aluminum and non-ferrous metals will find this bit a dependable choice for everyday jobber-length drilling work.

This drill bit is rated for primary use in aluminum and similar non-ferrous workpiece materials, as indicated by material code K, N, and P classifications. With an overall length of 5-19/32 inches and a flute length of 3-11/16 inches, it covers standard jobber-length reach requirements. The maximum drilling depth is 3.0680 inches. The right-hand cutting direction suits conventional drill press and handheld power tool setups. It is sold individually and is appropriate for both shop and field use where tight tolerances and clean hole finishes are required.

Key Features

• Cobalt construction provides heat resistance and edge retention in difficult materials
• 130-degree point angle reduces thrust and improves self-centering on entry
• Parabolic flute design enhances chip evacuation and reduces clogging
• Web-thinned tapered web lowers cutting resistance at drill entry
• DIN 338 standard ensures dimensional consistency and interchangeability
• Straight-cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as an OEM-specification jobber length drill bit conforming to DIN 338, suitable for use with standard straight-shank drill chucks in drill presses, CNC drilling centers, and handheld power tools where a 27/64 inch diameter is required.

Installation Notes

Secure the straight-cylindrical shank firmly in a properly sized drill chuck before operation. Ensure the drill press or power tool is powered down and unplugged before bit changes. Use appropriate cutting fluid or lubrication when drilling metals to extend tool life and maintain hole quality. Handle with care — cobalt drill bits are hard but can be brittle if subjected to side loading or dropped on hard surfaces.
