Value Collection 720-4018 Square End Mill 15/64 in 4 Flute Hss

Product Description

The VALUE COLLECTION 720-4018 is a double-end, four-flute square end mill manufactured from M2 high speed steel. It is designed for milling slots, profiles, and peripheral cuts in a wide range of ferrous and non-ferrous materials. The cutting diameter measures 15/64 inches (0.2344 inches decimal), with a 5/8-inch length of cut and a 3/8-inch shank diameter. The overall length is 3-3/8 inches. The bright, uncoated finish is standard for general-purpose HSS tooling. This end mill is installed and run by machinists and tool-and-die professionals on vertical milling machines, knee mills, and CNC machining centers.

This end mill suits light to medium-duty milling operations in job shop and production environments. The double-end configuration extends usable tool life by providing two cutting ends per tool. The 30-degree right-hand spiral flute geometry promotes chip evacuation and stable cutting action. It is appropriate for slotting, side milling, and contouring operations in mild steel, aluminum, brass, and similar machinable materials. The regular-length series fits standard toolholders and collet chucks without extended-reach concerns.

Key Features

• Double-end design provides two usable cutting ends per tool

Compatibility

Designed as a general-purpose OEM-style square end mill compatible with standard 3/8-inch collet chucks, end mill holders, and side-lock holders used on vertical milling machines and CNC machining centers.

Installation Notes

Installation should be performed by a qualified machinist following standard machine shop safety practices. Ensure the spindle is fully stopped and locked out before inserting or removing the tool from the holder. Verify the shank is clean and fully seated in the collet or holder to the recommended grip depth before tightening. This tool is not center-cutting and should not be used for direct plunge entry into solid material.
