Value Collection 720-3407 Square End Mill 1/2 in 4 Flute Hss

Product Description

The VALUE COLLECTION 720-3407 is a single-end 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, this tool delivers reliable performance in a wide range of materials. It measures 0.5 inches in diameter with a 3-inch length of cut and a 5-inch overall length, placing it in the extra-long category for applications requiring extended reach. The 30-degree helix angle promotes efficient chip evacuation, and the four-flute spiral configuration provides a balance of cutting speed and surface finish quality. Installation and setup are handled by machinists and CNC operators.

This end mill is suited for use in vertical machining centers, knee mills, and CNC milling machines where a 1/2-inch shank is required. The extra-long overall length makes it appropriate for deep-cavity milling, tall workpiece profiles, and setups where standard-length tooling cannot reach the cutting zone. The centercutting geometry allows plunge entry, expanding its use to slotting and pocket milling applications. Right-hand cutting and right-hand flute direction are standard for conventional spindle setups.

Key Features

• M2 high speed steel construction for durability in ferrous and non-ferrous materials
• 4-flute spiral design balances material removal rate and finish quality
• 30-degree helix angle promotes efficient chip evacuation
• Centercutting capable — supports plunge milling and slotting operations
• Extra-long 5-inch overall length for deep-reach applications
• Bright/uncoated finish — no coating thickness to account for in tight-tolerance fits

Compatibility

Designed as an OEM-style replacement or direct-use tooling option for any milling machine or machining center accepting a 1/2-inch round shank end mill holder, collet chuck, or shrink-fit toolholder.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Ensure the spindle is fully stopped and locked out before inserting or removing tooling. Secure the shank to the manufacturer-specified torque for the toolholder type in use. Verify runout with a dial indicator before beginning cuts, especially given the extra-long reach, which increases deflection sensitivity at elevated feed rates.
