Guhring 9055140092500 Carbide Screw Machine Drill Bit

Product Description

The GUHRING 9055140092500 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding industrial and trade applications. Built to DIN 6537K standards, this right-hand cut bit features a 140-degree split point (SU type) with web thinning for fast, accurate starts and reduced thrust. The 0.3642-inch (9.25 mm) diameter, two-flute spiral design delivers efficient chip evacuation in difficult materials. With an overall length of 89 mm and a 10 mm straight-cylindrical shank, it is suited for use in CNC machining centers, drill presses, and screw machine setups where consistency and tool life matter.

This drill bit is intended for professional machinists and metalworking tradespeople working with cast iron and steel. The screw machine (stub) length format provides added rigidity compared to jobber-length bits, reducing deflection in short-hole and high-cycle applications. It is appropriate for production drilling, maintenance machining, and precision fabrication environments where tight tolerances and reliable performance are required across repeated operations.

Key Features

• Solid submicron carbide construction for extended tool life in hard and abrasive materials
• 140-degree SU point with web thinning for self-centering entry and reduced walking
• Coated finish for improved wear resistance and heat management
• Two-flute regular spiral design with parallel web configuration for consistent chip flow
• DIN 6537K specification for dimensional accuracy and interchangeability
• 3xD flute-to-diameter ratio supports maximum drilling depth of 1.304 inches (33.13 mm)

Compatibility

Designed for use in cast iron and steel workpieces. Fits standard straight-cylindrical shank tool holders with a 10 mm shank bore. Suitable for CNC and manual machine setups consistent with Series 5514 Guhring tooling.

Installation Notes

Installation and use should be performed by qualified machinists familiar with carbide tooling. Ensure the machine spindle and tool holder are clean and properly seated before securing the shank. Carbide drill bits are brittle and should not be subjected to side loads or used in hand drills. Follow machine manufacturer speed and feed recommendations for the workpiece material to avoid tip fracture or premature wear.
