Guhring 9031890063500 Square End Mill 4 Flute Carbide

Product Description

The GUHRING 9031890063500 is a solid carbide square end mill engineered for precision milling in ferrous and non-ferrous materials. Part of the Series 3189 product line, it features a FIREX finish that improves heat resistance and extends tool life in demanding cutting conditions. The 4-flute, right-hand cut geometry with right-hand flutes and a 20-degree helix angle delivers efficient chip evacuation and a smooth surface finish. The centercutting design allows plunge entry, giving machinists flexibility in toolpath programming. This end mill is installed and operated by CNC machinists, tool-and-die makers, and precision metalworking professionals.

This end mill is suited for finish milling, slotting, profiling, and light plunge operations on machining centers and CNC mills. The fine pitch, regular-length configuration makes it appropriate for general-purpose work in shop environments where consistent dimensional accuracy is required. Its 0.25 inch diameter and 0.75 inch length of cut handle tight-tolerance features in mold work, fixture fabrication, and production part machining.

Key Features

• Solid carbide construction for rigidity and wear resistance
• FIREX coating enhances thermal resistance and extends tool life
• 4-flute, right-hand cut with right-hand flute orientation
• Centercutting design allows direct plunge entry
• 20-degree helix angle promotes efficient chip evacuation
• Fine pitch geometry for smooth surface finish

Compatibility

Designed as a standard shank end mill for use in ER collet chucks, end mill holders, and shrink-fit toolholders accepting a 0.25 inch shank diameter on CNC machining centers and manual mills.

Installation Notes

Installation and tool changes must be performed with the machine spindle fully stopped and the control in a safe state. Secure the 0.25 inch shank in a clean, properly sized collet or holder, torquing to the toolholder manufacturer's specification. Inspect the cutting edges and coating for chips or wear before each use. Follow shop safety standards and machine-specific operating procedures when setting tool length offsets and running first-article cuts.
