Guhring 9003360010700 Taper Length Drill Bit 0.0421 in

Product Description

The GUHRING 9003360010700 is a cobalt taper length drill bit designed for high-performance drilling in demanding materials. It carries a 0.0421-inch diameter with a 130-degree split point and a parabolic flute profile that promotes efficient chip evacuation and reduced heat buildup. The straight shank allows direct chuck mounting without adapters. Built to DIN 340 specification, this bit is web-thinned for easier entry and features a parallel web configuration for consistent rigidity through the cut. It is sold individually and is typically purchased by machinists, tool and die shops, and maintenance technicians working in production or repair environments.

This drill bit is suited for applications in cast iron, hardened materials, stainless steel, and carbon steel. The cobalt construction handles the elevated temperatures generated when cutting through tough or abrasive alloys. The taper length body provides additional reach compared to jobber-length bits, making it useful in setups where standard-length tooling cannot access the bore location. Right-hand cutting direction is standard for conventional drill press and CNC operations.

Key Features

• Cobalt tool material for high heat and wear resistance in tough alloys
• 130-degree point angle with web-thinned tip for reduced entry force
• Parabolic flute geometry promotes fast chip removal and reduces clogging
• DIN 340 taper length specification for extended reach over jobber-length bits
• Straight shank compatible with standard drill chucks
• Bright/uncoated finish maintains dimensional accuracy without coating buildup

Compatibility

Designed as an OEM-specification taper length drill bit per DIN 340, suitable for use in standard drill presses, CNC machining centers, and hand-held power tools accepting straight shank tooling in the 0.0421-inch diameter range.

Installation Notes

Installation is performed by machinists or maintenance technicians. Secure the straight shank firmly in a calibrated chuck before use and verify runout is within acceptable tolerance for the application. Do not exceed the recommended feed and speed parameters for the workpiece material. Inspect the cutting edges and point geometry before each use; replace the bit if chipping or deformation is observed.
