Guhring 9055100043000 Screw Machine Drill Bit

Product Description

The GUHRING 9055100043000 is a solid carbide screw machine length drill bit designed for high-performance drilling in cast iron and steel. Built to DIN 6537K standards, this bit features a 140-degree split point, web thinning, and coolant-through capability, making it well suited for demanding production and maintenance environments. The 4.30 mm (0.1693 inch) diameter and submicron carbide grade deliver tight tolerances and consistent hole quality. Licensed machinists, tool-and-die shops, and industrial maintenance technicians are the primary users of this type of precision tooling.

This drill bit is intended for use in CNC machining centers, drill presses, and screw machine operations where short, rigid tooling is required. Its screw machine length profile reduces deflection in close-tolerance applications. Primary workpiece materials are cast iron and steel. The coolant-through design supports high feed rates and extended tool life in production drilling cycles.

Key Features

• Solid carbide submicron grade construction for extended wear resistance in ferrous materials
• 140-degree SU point with web thinning reduces thrust and improves chip evacuation
• Coolant-through design supports high-speed production drilling
• Straight-cylindrical shank with 6.00 mm shank diameter for secure chuck retention
• Regular spiral, 2-flute configuration with 24.00 mm flute length
• Meets DIN 6537K specification; diameter tolerance of plus 0.004 to plus 0.016 mm

Compatibility

Designed as an OEM-style replacement or direct-fit option for Series 5510 screw machine length carbide drill applications requiring a 4.30 mm diameter bit per DIN 6537K. Suitable for use with standard straight-shank tool holders and chucks accepting a 6.00 mm shank.

Installation Notes

Installation should be performed by qualified machinists or toolroom technicians familiar with carbide tooling. Before inserting or removing the bit, ensure the spindle is fully stopped and the machine is de-energized or in a safe lockout state. Carbide tooling is brittle — avoid side loading, impact, or over-torquing set screws on the shank. Verify coolant-through passages are clear and coolant pressure is appropriate for the application before beginning production runs.
