Guhring 9055100031000 Screw Machine Drill Bit 0.122in

Product Description

The GUHRING 9055100031000 is a solid carbide screw machine length drill bit designed for high-performance drilling in ferrous and hard materials. Built to DIN 6537 K standards, this bit features a 140-degree split point (SU type) with web thinning for reduced thrust and cleaner entry. The 3.10 mm (0.122 inch) diameter, two-flute spiral design delivers precise, repeatable holes in cast iron and steel. Coolant-through capability supports high-speed production environments where heat management is critical. Licensed HVAC, plumbing, and mechanical contractors as well as machinists and tool-room professionals use this type of bit where tight tolerances and tool life are priorities.

This drill bit is suited for use in CNC machining centers, drill presses, and screw machine applications where a compact flute length and rigid solid carbide construction are required. The straight-cylindrical shank measures 6.00 mm in diameter, making it compatible with standard collet chucks and drill chucks used in production and maintenance machining. Primary workpiece materials include cast iron and steel, making this bit well-suited for HVAC equipment fabrication, mechanical panel work, and precision component drilling in trade-shop environments.

Key Features

• Solid carbide submicron grade construction for extended tool life in hard materials
• 140-degree SU split point with web thinning reduces entry thrust and walking
• Coolant-through design supports high-speed and deep-hole drilling cycles
• Regular spiral flute with parallel web configuration for consistent chip evacuation
• Coated finish improves wear resistance and surface lubricity
• Meets DIN 6537 K specification for dimensional accuracy and performance consistency

Compatibility

Designed as a high-performance OEM-style solid carbide drill bit for screw machine length applications in cast iron and steel workpieces, conforming to DIN 6537 K standards.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with carbide tooling. Before mounting, power down and lock out the machine spindle per applicable safety procedures. Solid carbide tooling is brittle — avoid side loading, interrupted cuts without proper feed rates, or dropping the bit on hard surfaces. Verify collet or chuck runout is within acceptable limits before use to prevent premature tool breakage.
