Value Collection 723-3228 Square End Mill 1-1/4 in 6 Flute

Product Description

The VALUE COLLECTION 723-3228 is a 6-flute cobalt square end mill designed for material removal and profiling operations on ferrous metals and high-temperature alloys. Built from M42 cobalt high-speed steel, this single-end tool carries a bright uncoated finish and a 30-degree right-hand spiral helix. The 1.25-inch cutting diameter and 2-inch length of cut make it well-suited for side milling, slotting, and peripheral finishing passes where tool rigidity and heat resistance are priorities. It is centercutting, allowing plunge entry without a pilot hole.

This end mill is used in manual mills, CNC machining centers, and knee mills common in job shops, maintenance shops, and production environments. The M42 grade cobalt steel provides increased red hardness compared to standard M2 HSS, making it a practical choice for cutting stainless steels, cast iron, and work-hardening alloys where carbide tooling is cost-prohibitive or chipping is a concern. The right-hand cutting direction is standard for conventional milling setups.

Key Features

• M42 cobalt HSS construction for elevated heat and wear resistance
• 6-flute geometry increases feed rate capability and improves surface finish
• 30-degree right-hand spiral helix for efficient chip evacuation
• Centercutting design allows direct plunge entry
• Bright uncoated finish — compatible with cutting fluids and oils without coating interaction concerns
• Single-end configuration with a 1.25-inch shank diameter matching the cutting diameter for straight-shank holders

Compatibility

Designed as a standard straight-shank square end mill for use in collet chucks, end mill holders, or Weldon-style side-lock holders with a 1.25-inch bore, common on manual and CNC vertical milling machines.

Installation Notes

Installation and removal should be performed with the machine spindle fully powered down and locked. Use a properly sized end mill holder or collet rated for 1.25-inch shanks and torque the retention hardware per the toolholder manufacturer specifications. Verify runout with a dial indicator before taking the first cut. Consult applicable shop safety standards and machine manufacturer guidelines when selecting speeds and feeds for the workpiece material.
