Guhring 9055140030000 Carbide Screw Machine Drill Bit

Product Description

The GUHRING 9055140030000 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding metalworking applications. Built to DIN 6537K standards, this bit features a 140-degree split point with web thinning for fast, accurate starts without a center punch. The straight-cylindrical shank measures 6.00 mm in diameter, and the overall length is 62.00 mm (approximately 2.44 inches). Two spiral flutes with a regular helix evacuate chips efficiently, and the coated finish extends tool life in abrasive materials. Right-hand cut geometry suits standard drill press and CNC spindle setups used by machinists and toolroom technicians.

This drill bit is intended for precision drilling in cast iron and steel workpieces. The screw machine length format provides added rigidity compared to jobber-length bits, making it well suited for short-reach holes in production environments, tool rooms, and maintenance shops. The 3xD flute-to-diameter ratio and a maximum drilling depth of 0.61 inches (15.50 mm) keep the tool stable in materials that demand tight tolerance and consistent hole quality. It is a single-piece, individually packaged bit suited for both manual drill press work and CNC applications.

Key Features

• Solid carbide construction with submicron carbide grade for hardness and wear resistance
• 140-degree SU point with web thinning for self-centering entry and reduced thrust
• Coated finish for extended tool life in cast iron and steel
• DIN 6537K specification compliance ensures dimensional consistency
• Screw machine length provides greater rigidity than jobber-length bits
• Right-hand spiral flute geometry promotes efficient chip evacuation

Compatibility

Designed for use in cast iron and steel workpieces. Fits standard drill chucks and CNC toolholders accepting a 6.00 mm straight-cylindrical shank. Part of GUHRING Series 5514.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom technicians familiar with cutting tool setup. Secure the shank fully in the chuck or collet before operation and verify runout before drilling. Power down the machine and lock out energy sources before changing tooling. Do not exceed the rated maximum drilling depth of 0.61 inches per pass without retracting to clear chips.
