Guhring 9055140039700 Carbide Drill Bit 5/32 in

Product Description

The GUHRING 9055140039700 is a solid carbide screw machine length drill bit designed for high-performance drilling in ferrous materials. It measures 0.1562 inches (5/32 inch) in diameter with a 140-degree point angle and a web-thinned SU point for reduced thrust and cleaner entry. The overall length is 66.00 mm with a flute length of 24.00 mm. The straight-cylindrical shank measures 6.00 mm in diameter. This bit is right-hand cut with a regular spiral flute and is manufactured to DIN 6537 K standards. It is installed and used by machinists, maintenance mechanics, and tool-and-die professionals requiring tight-tolerance, stub-length drilling.

This drill bit is suited for production drilling in cast iron and steel. The screw machine (stub) length format provides increased rigidity compared to jobber-length bits, making it effective in drill presses, CNC machining centers, and turret lathes where short overhang and precision entry are required. The 3xD flute-to-diameter ratio supports efficient chip evacuation in short-depth applications. Maximum drilling depth is 0.711 inches (18.05 mm). Coolant-through is not available on this model.

Key Features

• Solid carbide construction with coated finish for extended tool life in ferrous materials
• 140-degree split point (SU) with web thinning reduces entry thrust and walking
• Screw machine length provides rigid stub-style reach for high-precision drilling
• Right-hand cut with regular spiral flute geometry for consistent chip flow
• Manufactured to DIN 6537 K specification with parallel web configuration
• Diameter tolerance of +0.004 to +0.016 mm for close-tolerance hole sizing

Compatibility

Designed for drilling cast iron and steel workpieces. Fits standard straight-shank drill chucks and collet systems accepting a 6.00 mm shank diameter. Part of GUHRING Series 5514, covering the 0.1500 to 0.2000 decimal inch diameter range.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance professionals familiar with rotating cutting tools. Secure the shank fully in a drill chuck or collet before operation and verify runout is within acceptable limits. Always power down and de-energize the machine before changing tooling. Do not exceed the recommended maximum drilling depth of 0.711 inches for this stub-length geometry.
