Guhring 9055100070000 Carbide Drill Bit 0.2756 in

Product Description

The GUHRING 9055100070000 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding production environments. It features a 7.00 mm (0.2756 inch) diameter, a 140-degree split point with SU point geometry, and a web-thinned, parallel web configuration that reduces thrust and improves centering. The coated carbide construction and coolant-through design make it well-suited for applications where tool life and hole quality are critical. A right-hand, regular spiral flute evacuates chips efficiently, and the straight-cylindrical shank provides solid retention in standard drill chucks and collet holders. This bit is built to DIN 6537K specification.

This drill bit is intended for use in CNC machining centers, screw machines, and production drilling setups where short, rigid tooling is preferred over jobber-length bits. Primary target materials are cast iron and steel. The screw machine length format reduces overhang and deflection, making it a common choice for tight-tolerance hole work in metal fabrication, automotive component production, and general machining shops. The coolant-through capability supports both flood and high-pressure through-spindle coolant systems, extending tool life in interrupted or deep-feature cuts up to 30.00 mm drilling depth.

Key Features

• Solid carbide construction with submicron grade material for rigidity and wear resistance
• Coolant-through design supports through-spindle coolant for extended tool life
• 140-degree SU point with web thinning reduces entry thrust and improves self-centering
• Regular spiral flute with right-hand cut for efficient chip evacuation in ferrous materials
• Straight-cylindrical shank (8.00 mm) compatible with standard chucks and collet systems
• Meets DIN 6537K specification for screw machine length carbide drill geometry

Compatibility

Designed for use in CNC machining centers and production drilling equipment with spindles capable of accepting an 8.00 mm straight-cylindrical shank. Optimized for drilling cast iron and steel workpieces. Conforms to DIN 6537K standards for screw machine length carbide drills.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the spindle before tool changes. Ensure the shank seating surface and collet or chuck bore are clean and free of chips before clamping. Verify coolant passages are clear and coolant pressure is within the machine spindle's rated range before running the tool at operating speed.
