Value Collection 720-4304 Square End Mill 3/32 in 4 Flute Hss

Product Description

The VALUE COLLECTION 720-4304 is a double-end, 4-flute square end mill machined from M2 high speed steel. With a 3/32 inch (0.0938 inch) cutting diameter and a 5/32 inch (0.1563 inch) length of cut, this stub-length tool is built for short-reach profiling, slotting, and side milling in a wide range of ferrous and non-ferrous materials. The bright uncoated finish is standard for general-purpose HSS tooling. A 30-degree helix angle promotes efficient chip evacuation, and the centercutting geometry allows direct plunge entry without a pre-drilled pilot hole. Machinists and toolroom operators working on manual mills, CNC machining centers, and benchtop equipment will find this a reliable everyday cutter.

This end mill suits light-duty to medium-duty milling operations in job shops, maintenance departments, and production environments. Its stub length and 3/16 inch shank diameter make it appropriate for use in standard ER collets and end mill holders found on vertical milling machines and small CNC routers. The double-end design doubles usable tool life, allowing the operator to flip the tool when one end wears. Typical applications include keyway cutting, shoulder milling, and contour work in aluminum, mild steel, brass, and plastics.

Key Features

• Double-end design extends usable tool life — flip to the second cutting end when the first shows wear
• Centercutting flute geometry allows direct plunge milling without a pilot hole
• 30-degree helix angle for efficient chip flow during slotting and profiling cuts
• M2 high speed steel construction handles a broad range of common shop materials
• Bright uncoated finish — compatible with most cutting fluids and suitable for regrinding
• Stub-length (series VCCCDE-HSS-4) proportions provide added rigidity in short-reach applications

Compatibility

Designed as a general-purpose replacement or stock end mill for use in any machine tool accepting a 3/16 inch shank; fits standard ER collet chucks, end mill holders, and Weldon-style holders configured for that shank diameter.

Installation Notes

Installation and tool changes should be performed only after the spindle has been brought to a full stop and the machine has been locked out per shop safety procedures. Ensure the collet or holder is clean and free of chips before seating the shank to the recommended engagement depth. Right-hand cut and right-hand flute orientation require conventional spindle rotation — confirm machine direction before engaging the cut. Always wear appropriate eye protection and follow applicable OSHA and machine-tool manufacturer guidelines when changing or operating rotating cutters.
