Guhring 9055140032500 Screw Machine Drill Bit

Product Description

The GUHRING 9055140032500 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding production environments. Built to DIN 6537K standards, it features a 140-degree split point (SU type) with web thinning for reduced thrust and faster entry into the workpiece. The 0.128-inch diameter and 2-flush flute spiral geometry make this bit well suited for tight-tolerance hole making in cast iron and steel. Weighing 0.05 pounds, it is a compact, lightweight tool intended for use in CNC machining centers, screw machines, and other automated drilling equipment operated by machinists and tool-and-die professionals.

This drill bit is engineered for primary use in cast iron and steel workpieces, making it a practical choice for production shops running high-cycle drilling operations. The screw machine length format provides a shorter, more rigid profile compared to jobber-length bits, which reduces deflection and improves positional accuracy. The straight cylindrical shank allows direct chuck mounting in standard drill chucks and collet holders. It is suited for both manual and CNC-driven applications where hole depth is limited to the rated maximum drilling depth of 0.596 inches.

Key Features

• Solid carbide submicron-grade construction for wear resistance in ferrous materials
• 140-degree SU point with web thinning reduces cutting force and center walk
• DIN 6537K standard geometry ensures dimensional consistency and interchangeability
• Screw machine length profile provides added rigidity and reduced deflection
• 2-flute regular spiral design promotes chip evacuation in cast iron and steel
• Coated finish extends tool life in high-cycle production drilling

Compatibility

Designed as an OEM-style replacement or production tooling option for drilling operations in cast iron and steel, conforming to DIN 6537K specifications for screw machine length carbide drill bits in the 0.1000 to 0.1500 inch diameter range.

Installation Notes

Installation and use should be performed by a qualified machinist familiar with carbide tooling requirements. Ensure the machine spindle and chuck or collet are clean and properly seated before securing the straight cylindrical shank. Solid carbide tooling is brittle and should not be subjected to lateral loading or interrupted cuts beyond the tool's rated application. Always verify spindle speed and feed rate recommendations for carbide bits in the workpiece material before beginning a drilling cycle.
