Value Collection 720-3303 Square End Mill 5/16 in 4 Flute Hss

Product Description

The VALUE COLLECTION 720-3303 is a single-end, square-profile 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 offers reliable performance in a wide range of ferrous and non-ferrous materials. The 5/16 inch cutting diameter pairs with a 1-3/8 inch length of cut, giving machinists access to moderate-depth slots, pockets, and profiles. A 30-degree helix angle promotes smooth chip evacuation and balanced cutting forces. This tool is installed and operated by machinists, tool-and-die technicians, and CNC setup personnel working on vertical mills, knee mills, and CNC machining centers.

This end mill suits general metal removal applications in job shop, production, and maintenance machining environments. The long-series length type provides additional reach for applications where standard-length tools cannot access the full depth of a feature. The 3/8 inch shank diameter is compatible with standard collet chucks, end mill holders, and Weldon-style tool holders commonly found in both manual and CNC machine tool setups. Right-hand cut and right-hand flute direction make it a direct-fit for conventional spindle rotation. The tool is centercutting, allowing plunge entry directly into the workpiece without a pre-drilled pilot hole.

Key Features

• M2 high speed steel construction for durability across a broad range of workpiece materials
• 4-flute spiral geometry for improved surface finish and feed rate capability
• 30-degree helix angle promotes efficient chip flow and reduced cutting heat
• Centercutting design allows direct plunge milling without a starter hole
• Bright, uncoated finish suitable for use with cutting fluids or dry cutting depending on application
• Long-series length type for added reach in deep-feature applications

Compatibility

Designed as a standard fractional-inch shank end mill compatible with 3/8 inch collet chucks, end mill holders, and Weldon-style holders used in conventional vertical mills and CNC machining centers.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholding torque and runout specifications. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully and evenly in the holder to minimize runout and prevent pullout under load. Do not exceed the rated cutting diameter or depth-of-cut parameters for M2 HSS tooling in hard or abrasive materials.
