Guhring 9055100107000 Carbide Screw Machine Drill Bit

Product Description

The GUHRING 9055100107000 is a solid carbide screw machine length drill bit designed for high-performance drilling in cast iron and steel. Built to DIN 6537 K standards, this bit features a 140-degree split point with SU point geometry and web thinning for reduced entry force and improved chip evacuation. The 0.4213-inch (10.70 mm) diameter paired with a straight-cylindrical shank and coolant-through capability makes it well suited for production drilling environments where tool life and hole quality are priorities. Installation is handled by machinists and CNC operators in metal fabrication and machine shop settings.

This drill bit fits into screw machine length applications where a shorter, more rigid tool is needed for accuracy in shallow-to-moderate depth holes. The 3xD flute-to-diameter ratio and maximum drilling depth of 52.00 mm (approximately 2.05 inches) make it appropriate for through-holes and blind bores in cast iron and steel workpieces. The Series 5510 designation places it within a line of high-performance carbide tooling intended for demanding production cycles on CNC machining centers and drill presses equipped with coolant-through spindles.

Key Features

• Solid carbide construction for extended tool life in ferrous materials
• 140-degree SU point geometry with web thinning reduces thrust and improves centering
• Coolant-through design supports high-speed production drilling and chip flushing
• Right-hand spiral flute with regular helix promotes consistent chip evacuation
• Diameter tolerance of +0.007 to +0.025 mm for controlled hole sizing
• Conforms to DIN 6537 K specification for dimensional consistency

Compatibility

Designed for use in CNC machining centers and drill presses with coolant-through capability; primary workpiece materials are cast iron and steel. Fits straight-cylindrical toolholders sized for a 12.00 mm shank diameter.

Installation Notes

This tool is installed and operated by machinists or CNC programmers. Ensure the machine spindle and coolant-through system are fully powered down and depressurized before changing tooling. Verify the toolholder collet or chuck is clean and properly torqued to the manufacturer specification for the holder, not the drill. Confirm coolant-through flow rate and pressure are compatible with the spindle before initiating a cut in production material.
