Guhring 9055140059000 Carbide Screw Machine Drill Bit

Product Description

The GUHRING 9055140059000 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding trade and industrial applications. Built to DIN 6537 K standards, it features a 0.2323-inch diameter, a 140-degree split point (SU type), and a 2-flute right-hand spiral configuration with web thinning for improved chip evacuation and reduced thrust. The straight-cylindrical shank measures 6.00 mm in diameter, and the overall length is 66.00 mm. Submicron carbide grade construction and a coated finish extend tool life in abrasive and hard materials.

This drill bit is suited for precision hole-making in cast iron and steel across a range of production, maintenance, and fabrication environments. Its screw machine length profile makes it a practical choice for CNC machining centers, drill presses, and turret lathes where rigidity and tight tolerances are required. The 3xD flute-to-diameter ratio supports controlled chip removal at moderate drilling depths up to 0.754 inches (19.15 mm). It is well suited for production shops, tool rooms, and mechanical contractors working with ferrous materials.

Key Features

• Solid submicron carbide construction for extended tool life in cast iron and steel
• 140-degree SU split point with web thinning reduces walking and lowers feed force
• Coated finish improves wear resistance and heat dissipation
• DIN 6537 K specification ensures consistent dimensional standards
• Straight-cylindrical shank fits standard drill chucks and collet holders
• Screw machine length for maximum rigidity in short-reach applications

Compatibility

Designed as a screw machine length replacement or production drill for applications in cast iron and steel, conforming to DIN 6537 K. Compatible with standard straight-shank drill chucks and collets accepting a 6.00 mm shank diameter.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or trade professionals familiar with rotating cutting tools and machine tool safety. Ensure the machine spindle is fully stopped and power is locked out before changing tooling. Secure the shank firmly in a properly sized collet or chuck to prevent runout. Follow applicable workplace safety standards and machine manufacturer guidelines for speed and feed selection when drilling ferrous materials.
