Value Collection 720-4322 Square End Mill 3/32 in 4 Flute Hss

Product Description

The VALUE COLLECTION 720-4322 is a double-end, four-flute square end mill designed for precision milling operations in high-speed steel (HSS) construction. Built from M2 grade HSS, it delivers a good balance of wear resistance and toughness for general-purpose milling. The cutting diameter is 3/32 inches (0.0938 inches), with a length of cut of 9/32 inches (0.2813 inches) and a 3/16 inches shank diameter. The overall length is 2-1/4 inches. A 30-degree helix angle promotes efficient chip evacuation, and the bright/uncoated finish is suitable for use across a range of common workpiece materials. Machinists and tool-and-die trades use this style of end mill for slotting, profiling, and light contouring operations.

This end mill is suited for use in vertical milling machines, CNC machining centers, and manual knee mills in job shop, maintenance, and production environments. The double-end configuration provides two usable cutting ends per tool, extending service life before replacement. Right-hand cutting direction and right-hand flute direction are standard for conventional spindle setups. The centercutting geometry allows plunge milling in addition to peripheral cuts. It is appropriate for milling operations in ferrous and non-ferrous materials where an uncoated HSS tool meets application requirements.

Key Features

• Double-end design provides two usable cutting ends per tool
• M2 grade high speed steel construction for general-purpose milling
• 30-degree helix angle with spiral flutes for efficient chip evacuation
• Centercutting geometry allows plunge entry into workpiece
• Right-hand cut and right-hand flute for standard spindle compatibility
• Bright/uncoated finish — no coating to spall or delaminate

Compatibility

Designed as a standard fractional-inch shank end mill compatible with collets and tool holders accepting a 3/16 inches shank diameter in vertical mills, CNC machining centers, and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank in a properly sized collet or end mill holder, verifying adequate shank engagement before tightening. Follow the machine manufacturer guidelines and applicable shop safety procedures for tool speed and feed selection when placing the tool in service.
