Guhring 9030820063500 Square End Mill 1/4 in 4 Flute Carbide

Product Description

The GUHRING 9030820063500 is a solid carbide square end mill engineered for precision milling in demanding shop environments. Built to Series 3082 specifications, it features a FIREX finish that improves wear resistance and extends tool life in high-temperature cutting conditions. The four-flute, right-hand cut, right-hand flute geometry with a variable helix style and fine pitch promotes chip evacuation and reduces chatter. At 0.25 inches in diameter with a 0.75-inch length of cut and 2.5-inch overall length, this is a compact, rigid tool suited for slotting, profiling, and peripheral milling in tight workspaces. Center-cutting capability allows direct plunge entry without a pre-drilled pilot hole.

This end mill is designed for use in CNC machining centers, manual mills, and toolroom applications where tight tolerances are required. The regular-length configuration and 0.25-inch shank make it compatible with standard collet chucks and end mill holders common in production and job-shop settings. It is well suited for milling ferrous and non-ferrous metals, alloys, and hardened materials where a FIREX-coated carbide tool provides an advantage over uncoated or HSS alternatives. Machinists and tool-and-die professionals are the primary installers and users of this tooling.

Key Features

• Solid carbide construction for rigidity and extended tool life
• FIREX finish coating for improved heat and wear resistance
• Variable helix geometry with fine pitch reduces vibration and chatter
• Center-cutting design allows direct plunge milling
• Right-hand cut and right-hand flute for standard spindle compatibility
• Four-flute configuration balances chip evacuation with surface finish quality

Compatibility

Designed as an OEM-style solid carbide square end mill for use with standard 0.25-inch collet chucks and end mill holders in CNC and manual milling applications.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Secure the shank fully into the collet or end mill holder and torque to the tool holder manufacturer's specification before use. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Verify runout with a dial indicator after mounting to confirm proper seating and avoid premature tool wear or breakage.
