Value Collection 723-3220 Square End Mill 1 in 4 Flute Cobalt

Product Description

The VALUE COLLECTION 723-3220 is a single-end, 4-flute cobalt square end mill designed for milling operations that demand durability in tough or abrasive materials. Built from M42 cobalt high-speed steel, it delivers elevated heat resistance compared to standard HSS tooling, making it well suited for stainless steel, nickel alloys, and other difficult-to-machine metals. The mill features a 1 inch cutting diameter, a 1-7/8 inch length of cut, and a 4-1/8 inch overall length. A 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. The bright, uncoated finish is standard for cobalt tooling and is ready to run without additional surface treatment.

This end mill is used in vertical machining centers, knee mills, and manual milling machines across job shops, maintenance facilities, and production environments. It is suited for slotting, profiling, and peripheral milling in both ferrous and non-ferrous materials. The 3/4 inch shank diameter fits standard collets and end mill holders commonly used in these setups. With center-cutting capability, it can also be used for direct plunge entry where required.

Key Features

• M42 cobalt construction for improved heat and wear resistance over standard HSS
• 4 spiral flutes with right-hand cut and right-hand flute direction
• 30-degree helix angle for efficient chip evacuation
• Center-cutting design allows direct plunge milling
• Bright/uncoated finish — no coating buildup for consistent edge geometry
• Single-end configuration with regular length profile

Compatibility

Designed as an OEM-style replacement or direct-use end mill for standard 3/4 inch end mill holders, collet chucks, and milling machine spindles accepting fractional-inch shank tooling.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully powered down and at rest before changing tooling. Seat the shank fully in the holder to the recommended minimum engagement depth and torque set screws per the toolholder manufacturer specifications. Confirm runout with a dial indicator before beginning a cut, and verify feed and speed parameters are appropriate for the workpiece material and depth of cut.
