Guhring 9055100061000 Carbide Screw Machine Drill Bit

Product Description

The GUHRING 9055100061000 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding industrial applications. Built to DIN 6537 K standards, it features a 140-degree split point (SU type) with web thinning for reduced thrust and cleaner entry. The 2-flute spiral configuration provides efficient chip evacuation, and the straight-cylindrical shank seats securely in standard drill chucks and collets. At 0.2402 inches (6.10 mm) in diameter, this bit is suited for precision hole-making where tight tolerances and consistent finish are required. Coolant-through capability supports high-speed machining cycles in production environments.

This drill bit is engineered for use in cast iron and steel workpieces, making it a practical choice for machining centers, CNC drilling operations, and manual machine setups where short-length rigidity is preferred. The screw machine length format reduces deflection compared to jobber-length bits, which is especially useful in tight fixturing or when drilling near shoulders. Series 5510 from GUHRING targets high-performance applications where tool life and hole quality are production priorities.

Key Features

• Solid submicron carbide construction for extended tool life in ferrous materials
• 140-degree SU split point with web thinning reduces entry thrust and walking
• Coolant-through design supports high-speed and high-feed machining
• Screw machine length body provides added rigidity and reduced deflection
• Right-hand spiral flute with parallel web configuration for consistent chip flow
• Meets DIN 6537 K specification for dimensional accuracy and geometry

Compatibility

Designed as a high-performance OEM-style solid carbide drill for use in cast iron and steel workpieces; compatible with standard straight-shank drill chucks and collets accepting an 8.00 mm shank diameter.

Installation Notes

Installation and use should be performed by qualified machinists familiar with carbide tooling and CNC or manual drilling equipment. Ensure the machine spindle and chuck are fully powered down and secured before changing tooling. Carbide bits are brittle and must not be used in applications with interrupted cuts or excessive runout without proper setup. Verify coolant lines are clear and flowing before beginning coolant-through drilling operations.
