Guhring 9055140056000 Carbide Screw Machine Drill Bit

Product Description

The GUHRING 9055140056000 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding industrial and trade applications. With a 0.2205-inch diameter and a 140-degree split point, this bit delivers accurate entry and reduced thrust in ferrous materials. The coated finish extends tool life under repeated use. At 66.00 mm overall length with a 6.00 mm straight-cylindrical shank, it fits standard drill chucks and CNC tool holders. The web-thinned, parallel web construction minimizes walking and improves chip evacuation. Machining professionals, maintenance technicians, and fabrication shops will find this bit suited to tight-tolerance work in production environments.

This drill bit is built for right-hand cutting in cast iron and steel. The screw machine length format provides added rigidity compared to jobber-length bits, making it well suited for drill press work, CNC machining centers, and manual machine shop operations where stub-length control is required. The 3xD flute-to-diameter ratio supports chip clearing in shallow-to-moderate depth holes up to 0.772 inches deep. Two spiral flutes maintain consistent chip flow without clogging in continuous-cut applications.

Key Features

• 140-degree SU point with web thinning for fast, accurate entry and reduced thrust force
• Coated finish for extended wear resistance and heat management
• Straight-cylindrical 6.00 mm shank compatible with standard chucks and collets
• Maximum drilling depth of 0.772 inches (19.60 mm) with 3xD flute ratio
• Conforms to DIN 6537 K specification

Compatibility

Designed as a screw machine length carbide drill bit for use in drill presses, CNC machining centers, and manual milling machines equipped with chucks or collets accepting a 6.00 mm straight-cylindrical shank. Primary workpiece materials are cast iron and steel.

Installation Notes

This drill bit is installed and serviced by machinists, tool-and-die technicians, and maintenance professionals operating drill presses or CNC equipment. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable tolerance. Ensure the spindle is fully stopped before changing tooling. Do not exceed the maximum drilling depth of 0.772 inches without retracting to clear chips.
