Guhring 9055140119100 Carbide Drill Bit 0.4688 in

Product Description

The GUHRING 9055140119100 is a solid carbide screw machine length drill bit designed for high-performance drilling in ferrous materials. Built to DIN 6537 K standards, it features a 140-degree split point with SU geometry and a web-thinned, parallel web configuration for reduced entry force and improved centering. The 2-flute spiral design with a right-hand cut and straight-cylindrical shank suits standard drill chucks and CNC spindles alike. At 0.4688 inches (15/32 inch) in diameter, this bit is sized for close-tolerance applications where dimensional accuracy is critical. Licensed HVAC, mechanical, and industrial technicians working with cast iron or steel components will find this a reliable production-grade tool.

This drill bit is intended for use in cast iron and steel workpieces in both production and maintenance environments. Its screw machine length profile — shorter overall length for added rigidity — makes it well suited for CNC machining centers, drill presses, and manual screw machine operations where stub-length stability reduces runout. The coated carbide construction handles the heat generated in interrupted cuts and high-feed drilling cycles common in metal fabrication and equipment repair shops.

Key Features

• Solid carbide construction with coating for extended tool life in ferrous materials
• 140-degree SU split point improves self-centering and reduces thrust force
• Web-thinned parallel web lowers cutting resistance at entry
• 2-flute regular spiral design promotes chip evacuation in cast iron and steel
• Screw machine length (overall length 102.00 mm) provides increased rigidity versus jobber-length bits
• Meets DIN 6537 K specification for consistent dimensional tolerances (+0.007 to +0.025 mm diameter tolerance)

Compatibility

Designed for drilling cast iron and steel workpieces; compatible with standard straight-shank drill chucks and CNC tool holders accepting a straight-cylindrical shank at 0.4688 inches diameter. Suited for applications within the 0.4500 to 0.5000 inch drill bit size range per the Series 5514 product family.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with drill press and CNC spindle tooling. Confirm chuck or collet clamping is secure and concentric before operation to minimize runout. Coolant-through is not supported on this bit; external coolant or cutting fluid is recommended when drilling steel to manage heat buildup. Inspect the cutting edge for chipping before each use — carbide is brittle and susceptible to damage from improper handling or interrupted cuts without adequate feed control.
