Value Collection 722-4008 Square End Mill 5/32 in 4 Flute Hss

Product Description

The VALUE COLLECTION 722-4008 is a double-end, 4-flute square end mill designed for general-purpose milling operations in metal, composite, and plastics. Manufactured from M2 high speed steel with a titanium nitride (TiN) coating, it offers improved wear resistance and surface lubricity compared to uncoated HSS. The cutting end measures 5/32 inch (0.1563 inch) in diameter with a 7/16 inch (0.4375 inch) length of cut and a 30-degree right-hand spiral flute geometry. The 3/8 inch shank seats in standard collet chucks and end mill holders. This tool is installed and used by machinists and tool-and-die professionals working on manual mills, CNC knee mills, and light-duty machining centers.

This end mill is suited for slotting, peripheral milling, and profiling passes on ferrous and non-ferrous workpieces where a small-diameter cutter is required. The double-end configuration extends usable tool life by providing a second cutting end once the first is worn. Right-hand cut and right-hand flute orientation make it compatible with conventional spindle rotation on standard milling equipment. It is a practical choice for short-run production, tool room work, and maintenance machining where HSS tooling is preferred over carbide for its toughness and regrindability.

Key Features

• M2 high speed steel construction for toughness and regrindability
• TiN coating reduces friction and extends tool life versus uncoated HSS
• Double-end design provides two usable cutting ends per tool
• 30-degree right-hand spiral flute for efficient chip evacuation
• 4-flute geometry delivers improved surface finish on finishing passes
• Non-centercutting — not suited for plunge milling; ramp or helical entry required

Compatibility

Designed as a general-purpose replacement or stock end mill for use with standard 3/8 inch collet chucks and end mill holders on manual or CNC milling machines.

Installation Notes

Installation is performed by machinists using a collet chuck or end mill holder rated for the 3/8 inch shank diameter. Ensure the machine spindle is fully stopped and locked before loading or removing the tool. Confirm runout is within acceptable limits after seating to avoid premature edge wear. Because this end mill is not centercutting, avoid direct plunge entry into solid material — use a ramping or helical toolpath instead.
