Guhring 9055140046500 Screw Machine Drill Bit

Product Description

The GUHRING 9055140046500 is a screw machine length solid carbide drill bit engineered for high-performance drilling in demanding production environments. It measures 0.1831 inches (4.65 mm) in diameter with a 140-degree split point angle and a web-thinned geometry that reduces entry force and improves centering accuracy. The 2-flute spiral design promotes efficient chip evacuation, and the straight-cylindrical shank allows direct chucking in standard drill chucks or collets. With an overall length of 66 mm and a flute length of 24 mm, this bit is built for short, rigid setups typical of CNC machining centers, screw machines, and automated drilling fixtures. It conforms to DIN 6537 K specifications and is manufactured from submicron-grain solid carbide with a coated finish for extended tool life.

This bit is suited for drilling cast iron and steel in high-volume production or precision machining applications. The screw machine length (stub) configuration provides the rigidity needed when working in tight setups or on materials that demand consistent hole geometry and dimensional accuracy. A maximum drilling depth of 0.67 inches (17.03 mm) and a 3xD flute-to-diameter ratio make it well matched for through-hole and shallow blind-hole operations on ferrous workpieces. It is typically installed and operated by machinists and CNC technicians in shop environments requiring repeatable tooling performance.

Key Features

• Solid submicron-grain carbide construction for hardness and wear resistance in ferrous materials
• 140-degree point angle with web-thinned, parallel web configuration for reduced thrust and improved self-centering
• Coated finish extends cutting edge life in cast iron and steel applications
• Right-hand cut, regular spiral flute promotes clean chip removal in through and shallow blind holes
• Straight-cylindrical shank (6.00 mm) compatible with standard drill chucks and collets
• Conforms to DIN 6537 K specification for dimensional consistency and interchangeability

Compatibility

Designed as a DIN 6537 K conforming screw machine length drill bit for use in cast iron and steel workpieces. Compatible with any standard drill chuck or collet system accepting a 6.00 mm straight-cylindrical shank. Suitable for CNC machining centers, screw machines, and automated drilling equipment configured for stub-length tooling.

Installation Notes

Installation and operation should be performed by qualified machinists or CNC technicians familiar with toolholding systems and cutting parameters for solid carbide tooling. Ensure the machine spindle and toolholder are clean and free of debris before seating the shank. Carbide is brittle and susceptible to chipping from lateral shock or interrupted cuts at incorrect feed rates — consult the machine tool documentation for appropriate speeds and feeds for the workpiece material. Do not use this bit on materials outside its rated primary workpiece material range without verifying carbide grade suitability.
