Value Collection 720-3211 Square End Mill 0.5 in 4 Flute Hss

Product Description

The VALUE COLLECTION 720-3211 is a 4-flute, single-end square end mill designed for general-purpose milling operations in ferrous and non-ferrous materials. Manufactured from M2 high speed steel with a bright uncoated finish, it delivers reliable cutting performance across a range of conventional milling tasks. The tool features a 0.5 inch cutting diameter, a 1.25 inch length of cut, and a 0.5 inch straight shank. A 30-degree helix angle promotes efficient chip evacuation, and the centercutting geometry allows plunge entry directly into workpiece material. Machinists and toolroom operators install this end mill in manual knee mills, CNC machining centers, and drill press setups.

This end mill suits light-to-medium stock removal in job shop, maintenance, and production environments. Its regular-length profile and fractional inch sizing make it a standard choice for slotting, profiling, and peripheral milling in steel, aluminum, and similar materials. The right-hand cut and right-hand spiral flute configuration is compatible with conventional spindle rotation on standard milling machines. No coolant-through capability is present, so flood or mist coolant applied externally is the standard cooling method for steel cutting applications.

Key Features

• M2 high speed steel construction for general-purpose durability across a broad range of workpiece materials
• 4-flute geometry balances chip load and surface finish on slotting and profiling passes
• 30-degree helix angle promotes chip evacuation and reduces cutting forces
• Centercutting design allows direct plunge cutting without a pre-drilled pilot hole
• Bright uncoated finish suits applications where coating adhesion or contamination is a concern
• Single-end, regular-length configuration fits standard tool holders and collet chucks

Compatibility

Designed as a standard fractional-inch single-end square end mill for use in milling machines, CNC machining centers, and compatible rotary tool holders accepting a 0.5 inch straight shank.

Installation Notes

A licensed machinist or qualified toolroom operator should install this end mill in a collet chuck or end mill holder rated for the shank diameter. Ensure the machine spindle is fully stopped and locked out before changing tooling. Confirm runout with a dial indicator after seating the shank to the recommended engagement depth. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed selection based on workpiece material.
