Guhring 9055100062000 Carbide Screw Machine Drill Bit

Product Description

The GUHRING 9055100062000 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding production environments. Built to DIN 6537K standards, it measures 6.20 mm (0.2441 inches) in diameter with a 140-degree split point (SU type) for accurate self-centering entry. The two-flute spiral design runs 34.00 mm in flute length over a 79.00 mm overall length, and the web-thinned, parallel web construction reduces thrust and improves chip evacuation. Coolant-through capability makes it well-suited for deep-hole applications where heat and chip removal are critical. This bit is installed by machinists and tool-and-die professionals working in precision drilling operations.

This drill bit is intended for use in cast iron and steel workpieces in screw machine and short-hole drilling applications. Its 3xD flute-to-diameter ratio supports a maximum drilling depth of 30.00 mm. The straight-cylindrical shank measures 8.00 mm in diameter, fitting standard collet chucks and drill chucks used on CNC machining centers, drill presses, and screw machines. It is rated as a high-performance grade tool appropriate for production runs requiring consistent hole tolerance and surface finish.

Key Features

• Solid carbide submicron grade construction for extended tool life in ferrous materials
• 140-degree SU split point for accurate entry and reduced walking on hard surfaces
• Coolant-through design supports effective chip flushing and heat control at depth
• Web-thinned parallel web reduces axial thrust during drilling
• DIN 6537K specification ensures dimensional consistency and interchangeability
• Right-hand cut, regular spiral flute optimized for cast iron and steel

Compatibility

Designed as an OEM-style replacement and production drill bit for use in CNC machining centers, screw machines, and drill presses accepting an 8.00 mm straight-cylindrical shank. Primary workpiece materials are cast iron and steel.

Installation Notes

Installation and use should be performed by qualified machinists familiar with cutting tool setup and machine operation. Ensure the machine spindle is fully stopped and locked out before changing tooling. Secure the straight-cylindrical shank fully within the collet or chuck to the recommended grip depth before operation. Verify coolant-through supply lines are connected and functioning before engaging the drill in deep-hole operations.
