Guhring 9055140040000 Carbide Screw Machine Drill Bit

Product Description

The GUHRING 9055140040000 is a solid carbide screw machine length drill bit designed for high-performance drilling in ferrous materials. Built to DIN 6537K standards, this bit features a 140-degree split point (SU type) with web thinning for fast penetration and reduced thrust. The 2-flute spiral configuration handles chip evacuation in tough materials. At 0.1575 inches in diameter with a 6 mm straight-cylindrical shank, it fits standard drill chucks and machining center toolholders. Right-hand cut geometry and a coated finish extend tool life in demanding production environments. Licensed HVAC technicians, machinists, and maintenance professionals working with cast iron and steel components reach for this series when precision hole location and tool longevity matter.

The 9055140040000 is suited for drilling cast iron and steel workpieces in screw machine, CNC, and manual drilling applications. The screw machine length format — shorter overall length for rigidity — makes it a practical choice for close-tolerance work on small components, valve bodies, manifolds, and similar metal parts. Maximum drilling depth reaches 0.709 inches (18 mm), covering most through-hole and blind-hole requirements at this diameter. The Series 5514 designation identifies it within the GUHRING submicron carbide grade lineup, intended for high-speed, high-feed cutting strategies.

Key Features

• Solid submicron carbide construction for extended tool life in ferrous materials
• 140-degree SU split point with web thinning reduces thrust and improves self-centering
• Coated finish resists wear and heat buildup during high-speed drilling
• Screw machine length body provides rigidity for close-tolerance hole placement
• Parallel web configuration maintains consistent cutting geometry throughout flute length
• Conforms to DIN 6537K specification for dimensional consistency

Compatibility

Designed as a high-performance OEM-style solid carbide drill for use in cast iron and steel workpieces; compatible with standard straight-shank drill chucks and toolholders accepting a 6 mm shank diameter.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or maintenance technicians familiar with CNC or manual drilling equipment. Ensure the machine spindle and toolholder are powered down and fully stopped before inserting or removing the bit. Verify shank diameter compatibility with the collet or chuck before tightening to the manufacturer-specified clamping torque for that toolholder type. Do not exceed the recommended maximum drilling depth of 0.709 inches without retracting to clear chips.
