Guhring 9055100057000 Carbide Screw Machine Drill Bit

Product Description

The GUHRING 9055100057000 is a solid carbide screw machine length drill bit engineered for high-performance drilling in demanding production environments. Measuring 0.2244 inches (5.70 mm) in diameter with a 140-degree split point and coolant-through capability, this bit is built for accuracy and tool life in tough materials. The straight-cylindrical shank and web-thinned geometry reduce entry force and improve chip evacuation. It is installed and used by machinists, tool-and-die professionals, and precision fabricators working on CNC machining centers and production drilling equipment.

This drill bit is rated for use in cast iron and steel workpieces, making it suitable for general metalworking, job shop production, and automated machining operations. The screw machine length format keeps the bit compact and rigid, reducing deflection in short-reach drilling applications. With a 3xD flute-to-diameter ratio and a maximum drilling depth of 25.00 mm, it fits standard production setups where repeatability and hole quality are priorities. The Series 5510 designation identifies it within the GUHRING high-performance carbide drill lineup.

Key Features

• Solid carbide construction for extended tool life in ferrous materials
• Coolant-through design supports high-speed production drilling and chip flushing
• 140-degree drill point angle with SU point type reduces thrust and improves entry accuracy
• Web-thinned, parallel web configuration lowers cutting resistance at drill entry
• 2-flute regular spiral design promotes efficient chip evacuation
• Complies with DIN 6537 K specification for dimensional consistency

Compatibility

Designed as a high-performance OEM-style carbide drill for use in CNC machining centers and production drilling equipment targeting cast iron and steel workpiece materials.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with carbide tooling requirements. Secure the straight-cylindrical shank fully in an appropriate collet or drill chuck rated for the spindle speed being used. Enable coolant-through supply before starting the cut to protect the carbide substrate and clear chips from the flutes. Carbide tooling is brittle — avoid side loading, interrupted cuts without proper parameters, or dropping the bit on hard surfaces.
