Guhring 9055100120000 Carbide Drill Bit 0.4724 in

Product Description

The GUHRING 9055100120000 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding industrial and metalworking applications. Built to DIN 6537K standards, this right-hand cut drill features a 12.00 mm (0.4724 inch) diameter, a 140-degree split point (SU point type), and through-coolant capability for extended tool life in high-cycle operations. The submicron carbide grade and coated finish allow it to handle cast iron and steel at elevated feeds and speeds without premature wear. A web-thinned, parallel web configuration reduces thrust load at entry and improves chip evacuation through the spiral flutes. Licensed machinists and tool-room technicians rely on this bit for precision hole-making where dimensional consistency is critical.

This drill is suited for production machining environments including CNC machining centers and screw machine operations where short, rigid tooling is preferred. Its screw machine length profile limits overhang and deflection, making it a practical choice for tight-tolerance bore work in cast iron and steel components. The 3xD flute-to-diameter ratio and 52.00 mm maximum drilling depth fit standard roughing and finishing cycles in job shop and production floor settings alike.

Key Features

• Solid submicron carbide construction for extended tool life in ferrous materials
• Through-coolant design channels fluid directly to the cutting edge for heat management
• 140-degree SU split point reduces thrust and improves self-centering at entry
• Web-thinned parallel web lowers cutting resistance and promotes chip flow
• Coated finish enhances surface hardness and wear resistance
• DIN 6537K standard ensures dimensional interchangeability with compatible toolholders

Compatibility

Designed as a DIN 6537K screw machine length drill for use in straight-cylindrical shank toolholders accepting a 12.00 mm shank diameter. Rated for primary workpiece materials of cast iron and steel.

Installation Notes

Installation and setup should be performed by qualified machinists or toolroom technicians. Ensure the machine spindle and toolholder are fully de-energized and at rest before changing tooling. Confirm the straight-cylindrical shank is seated cleanly and clamped to the appropriate torque specification for the toolholder in use. When running with coolant-through capability, verify that coolant pressure and flow rate meet the requirements of the machine setup before beginning a cut.
