Value Collection 720-4320 Square End Mill 5/64 in 4 Flute Hss

Product Description

The VALUE COLLECTION 720-4320 is a double-end, four-flute square end mill manufactured from M2 high speed steel. Designed for milling operations in metalworking and machining environments, this tool delivers precise square shoulder cuts and slot milling across a range of ferrous and non-ferrous materials. The 5/64 inch (0.0781 inch) diameter and 15/64 inch (0.2344 inch) length of cut make it well suited for fine detail work and tight-tolerance features. With a bright, uncoated finish and a 30-degree helix angle, it provides clean chip evacuation on conventional machining centers and manual mills alike. Machinists and tool-and-die professionals working in job shops, production floors, and toolroom environments are the primary users of this type of cutter.

This end mill is intended for use in machining applications requiring a small-diameter square profile cutter. The double-end design extends tool life by providing two usable cutting ends. The 3/16 inch (0.1875 inch) shank diameter is compatible with standard collets and end mill holders found on vertical machining centers, knee mills, and CNC routers. The regular length classification and 2-1/4 inch (2.2500 inch) overall length suit typical setups where extended reach is not required. This cutter is sold individually and is appropriate for both production runs and one-off toolroom work.

Key Features

• Double-end design provides two cutting ends for extended tool life
• M2 high speed steel construction offers toughness and wear resistance across a range of workpiece materials
• Four flutes with right-hand spiral at 30-degree helix angle for efficient chip evacuation
• Center-cutting capability allows plunge entry into workpieces
• Bright, uncoated finish compatible with standard cutting fluids and lubricants
• Right-hand cutting direction for use with conventional spindle rotation

Compatibility

Designed as an OEM-style replacement or direct-use tool for machining setups requiring a 3/16 inch shank, small-diameter square end mill in standard collet or end mill holder tooling systems.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholding specifications. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the collet or end mill holder to the recommended engagement depth before torquing the retention hardware. Verify runout with a dial indicator before beginning a cut, particularly given the small diameter of this tool.
