Guhring 9055120052000 Taper Length Drill Bit 5.2mm

Product Description

The GUHRING 9055120052000 is a solid carbide taper length drill bit in the Series 5512 product line, designed for precision drilling in demanding production and machining environments. It features a 5.2 mm (0.2047 inches) diameter, a 140-degree point angle with a self-centering SU point type, and a FIREX coating for extended tool life and heat resistance. The straight cylindrical shank measures 6 mm in diameter, and the overall length is 90 mm (3.54 inches). Coolant-through capability supports high-speed drilling in harder materials. This bit is installed and used by machinists, tooling technicians, and CNC operators working in metal fabrication and precision manufacturing.

The 9055120052000 is suited for applications requiring tight hole tolerances in metals and hard alloys. The 7xD flute-length-to-diameter ratio and 50 mm (1.97 inches) flute length make it appropriate for moderate-depth holes in production drilling setups. The web-thinned, tapered web configuration reduces thrust and improves chip evacuation. This bit performs in both manual drill press operations and CNC machining centers where consistent, repeatable hole geometry is required.

Key Features

• Solid carbide construction from DK460UF material grade for rigidity and wear resistance
• FIREX coating provides thermal protection and reduces friction in high-speed applications
• Coolant-through design supports internal coolant delivery to the cutting zone
• Self-centering SU point type with 140-degree angle reduces pilot hole requirements
• Web-thinned, tapered web reduces cutting force and improves chip flow
• Right-hand spiral flute with regular spiral type for standard CNC and drill press use

Compatibility

Designed as an OEM-style replacement or direct tooling selection for applications conforming to DIN 6537 taper length drill bit standards. Straight cylindrical shank is compatible with standard drill chucks and collet systems sized for 6 mm shank diameters.

Installation Notes

Installation is performed by machinists or CNC setup technicians. Before mounting, ensure the machine spindle and chuck or collet are fully powered down and locked out per facility lockout/tagout procedures. Confirm shank seating depth and runout with a dial indicator before beginning production drilling. Do not exceed the maximum drilling depth of 42.20 mm (1.66 inches) to avoid tool deflection or breakage.
