Value Collection 720-3609 Square End Mill 5/8 in Hss

Product Description

The VALUE COLLECTION 720-3609 is a single-end square end mill designed for milling flat-bottomed pockets, slots, and peripheral profiles in a wide range of metals and engineering materials. Built from M2 high speed steel with a bright uncoated finish, it measures 5/8 inches in diameter with a matching 5/8-inch shank and delivers a 4-inch length of cut — an extra-long configuration suited to deep-reach milling applications. The 30-degree right-hand spiral provides efficient chip evacuation and smooth cutting action. Four flutes give a balance between chip clearance and surface finish. This tool is installed and operated by machinists and tool-and-die professionals on manual mills and CNC machining centers.

This end mill is appropriate for general-purpose milling in job shop, production, and maintenance environments where a longer reach is required. The extra-long 6-1/8-inch overall length allows access to deep features that standard-length tools cannot reach. The non-centercutting geometry means this tool is intended for side milling, slotting, and peripheral profiling rather than direct plunge cuts. It suits applications in steel, aluminum, brass, cast iron, and similar machinable materials where HSS tooling is specified or preferred over carbide.

Key Features

• M2 high speed steel construction provides toughness and wear resistance for general-purpose milling
• Extra-long configuration with 4-inch length of cut and 6-1/8-inch overall length for deep-reach applications
• Four right-hand spiral flutes at 30-degree helix angle for efficient chip evacuation
• Bright uncoated finish — no additional coating to interfere with close-tolerance shank fits
• Single-end design with right-hand cutting direction
• Non-centercutting — optimized for peripheral and slot milling, not plunge entry

Compatibility

Designed as an OEM-style replacement or direct-fit tool for standard 5/8-inch collet chucks, end mill holders, and milling machine spindles accepting a 5/8-inch straight shank.

Installation Notes

Installation and tool changes must be performed with the machine spindle fully stopped and the machine powered down or placed in a safe lockout state per applicable shop safety procedures. Secure the shank in a clean, properly sized collet or end mill holder and torque to the holder manufacturer specification. Inspect the shank and flutes for damage before mounting. Confirm that the holder provides sufficient reach clearance so the cutting edges do not contact the holder face during operation.
