Guhring 9031820063500 Square End Mill 1/4 in 6 Flute

Product Description

The GUHRING 9031820063500 is a 6-flute solid carbide square end mill designed for high-performance milling in hard materials and cast iron. Built on GUHRING Series 3182, it features a FIREX coating and a 55-degree helix angle that promotes efficient chip evacuation and thermal resistance at the cutting edge. The 0.25-inch diameter pairs with a 0.75-inch length of cut, making this a compact but capable tool for finishing and semi-finishing passes. Centercutting geometry allows plunge entry. This end mill is installed and operated by CNC machinists and tool-and-die professionals working on close-tolerance components.

This end mill is suited for milling hard steels, hardened tool steels, and cast iron in both production and job-shop environments. The straight cylindrical shank accepts standard collet chucks and hydraulic toolholders sized for a 0.25-inch bore. Its regular-length profile fits most vertical machining center setups where clearance is not a limiting factor. The right-hand cut and right-hand spiral flute configuration is standard for conventional CNC milling spindles.

Key Features

• 6-flute geometry increases feed rate capability and surface finish quality in hard materials
• FIREX coating provides heat and wear resistance for extended tool life in ferrous alloys
• 55-degree helix angle promotes smooth cutting action and chip flow
• Centercutting design allows direct plunge milling without a pilot hole
• Solid carbide construction delivers rigidity and dimensional stability under high cutting loads
• Right-hand cut and right-hand flute configuration compatible with standard CNC spindle rotation

Compatibility

Designed for use in CNC machining centers and milling machines accepting a 0.25-inch straight cylindrical shank. Primary workpiece materials are hard steels (material code H) and cast iron (material code K) per GUHRING Series 3182 application guidelines.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom personnel. Secure the shank in a collet chuck or hydraulic toolholder to the full recommended grip length before use; do not expose more shank than necessary. Confirm spindle rotation direction matches the right-hand cut specification before starting the program. Follow machine tool manufacturer torque specifications for drawbar and toolholder retention.
