Value Collection 720-3503 Square End Mill 5/16 in 4 Flute Hss

Product Description

The VALUE COLLECTION 720-3503 is a 4-flute square end mill designed for general-purpose milling operations in metal fabrication and machining environments. Built from M2 high speed steel with a bright uncoated finish, it measures 5/16 inches in diameter with a 1-3/8 inch length of cut and a 3-1/8 inch overall length. The 3/8 inch shank diameter provides solid tool holder engagement, and the 30-degree helix angle promotes efficient chip evacuation during cuts. This is a single-end, right-hand cutting tool suited for machinists running manual mills or CNC machines at moderate speeds and feeds.

This end mill is appropriate for slotting, profiling, and peripheral milling on ferrous and non-ferrous materials where HSS tooling is preferred over carbide. The long-series classification extends reach compared to standard-length end mills, making it useful when additional clearance is needed in pockets or stepped workpieces. It is a fractional-inch, spiral-flute tool without chipbreaker geometry, making it a straightforward choice for general shop use.

Key Features

• M2 high speed steel construction for toughness in general machining applications
• 4 spiral flutes with 30-degree helix angle for efficient chip flow
• Long-series length type for extended reach in deep pockets or stepped features
• Right-hand cut and right-hand flute orientation — compatible with standard spindle direction
• Bright uncoated finish — suitable for use with cutting fluid or light dry cutting
• Single-end design — replace when worn rather than flip

Compatibility

Designed as a standard fractional-inch shank end mill compatible with 3/8 inch collets and end mill holders on manual knee mills, bridgeport-style machines, and CNC machining centers accepting 3/8 inch shank tooling.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is powered off before inserting or removing the tool from the holder. Secure the shank to the full recommended engagement depth in the collet or end mill holder to minimize runout and prevent pullout under load. Do not exceed the tool's rated cutting parameters for the workpiece material.
