Value Collection 720-3055 Square End Mill 5/8 in 4 Flute Hss

Product Description

The VALUE COLLECTION 720-3055 is a single-end, square-profile end mill designed for general-purpose milling operations in machine shops and production environments. Ground from M2 high speed steel with a bright/uncoated finish, it features a 5/8 inch diameter cutting edge, a 1-5/8 inch length of cut, and a 30-degree helix angle across four right-hand spiral flutes. The 5/8 inch straight shank and 3-3/4 inch overall length make it compatible with standard milling machine collets and tool holders. This tool is installed and used by machinists performing slotting, profiling, and peripheral milling on ferrous and non-ferrous workpieces.

This end mill is suited for conventional vertical and horizontal milling operations on manual knee mills, CNC machining centers, and similar equipment. The four-flute configuration balances chip evacuation with surface finish quality, making it a practical choice for finishing passes and moderate material removal rates. The bright/uncoated finish is appropriate for dry cutting or cutting with standard coolant on steels, cast iron, and similar materials where an advanced coating is not required.

Key Features

• M2 high speed steel construction for durability across a range of workpiece materials
• Four right-hand spiral flutes with a 30-degree helix angle for efficient chip flow
• 5/8 inch cutting diameter with a matching 5/8 inch shank diameter for concentric tool holding
• 1-5/8 inch length of cut suitable for moderate-depth slotting and profiling
• Bright/uncoated finish — no coating delamination risk during regrind cycles
• Single-end design; right-hand cutting direction for standard spindle rotation

Compatibility

Designed as an OEM-style replacement or direct-use end mill compatible with standard milling collets and end mill holders accepting a 5/8 inch straight shank.

Installation Notes

Installation is performed by machinists using a properly sized collet or end mill holder torqued according to the machine tool manufacturer specification. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool. Confirm runout with a dial indicator after tool installation to avoid premature edge wear. This tool is not center-cutting and should not be used for direct plunge entry into solid material.
