Guhring 9055100067000 Carbide Drill Bit 0.2638 in

Product Description

The GUHRING 9055100067000 is a solid carbide screw machine length drill bit designed for high-performance drilling in ferrous materials. It measures 0.2638 inches (6.70 mm) in diameter with a 140-degree split point geometry and a web-thinned, parallel web configuration that reduces entry force and improves centering. The 2-flute spiral design provides efficient chip evacuation, and the through-coolant capability supports higher feed rates and extended tool life in production environments. At 79.00 mm overall length with a 34.00 mm flute length, this bit is built for short, rigid setups common in CNC machining and screw machine work. Licensed machinists and tooling technicians are the primary installers.

This drill bit is suited for drilling cast iron and steel in both production and job-shop environments. Its screw machine length profile offers increased rigidity compared to jobber-length bits, making it well-matched to high-cycle applications where runout and deflection must be minimized. The straight-cylindrical shank diameter of 8.00 mm seats directly in standard collet chucks and drill chucks without adapters. The coated finish supports performance in demanding cutting conditions. Series 5510 conforms to DIN 6537 K standards, making it a direct fit where metric-standard tooling is specified.

Key Features

• Solid carbide submicron-grade construction for wear resistance in cast iron and steel
• 140-degree SU point with web thinning reduces thrust and improves hole entry accuracy
• Through-coolant design supports high-feed CNC drilling and extended tool life
• Screw machine length profile provides superior rigidity over jobber-length alternatives
• 2-flute spiral configuration with parallel web for consistent chip evacuation
• Conforms to DIN 6537 K specification for metric tooling standardization

Compatibility

Designed for use in cast iron and steel applications as specified by the manufacturer. Primary workpiece materials are cast iron and steel. Fits standard collet chucks and drill chucks accepting an 8.00 mm straight-cylindrical shank. Conforms to DIN 6537 K standards.

Installation Notes

Installation and tooling changes should be performed by qualified machinists or tooling technicians with the machine powered down and locked out per applicable safety procedures. Verify chuck or collet runout before use, as excess runout will shorten carbide tool life significantly. Do not use this bit in hand-held drilling applications; it is intended for rigid machine-tool setups only. Through-coolant passages should be flushed and confirmed clear before mounting.
