Value Collection 720-1577 Square End Mill 2 in Hss

Product Description

The VALUE COLLECTION 720-1577 is a single-end, square-profile end mill designed for material removal in milling operations on aluminum and non-ferrous workpieces. Built from M2 high speed steel with a bright, uncoated finish, it features a 2-inch cutting diameter, a 4-inch length of cut, and a 6.5-inch overall length that places it in the long-series category. The 2-flute geometry and 37-degree helix angle support efficient chip evacuation in softer materials. Right-hand cutting and right-hand flute direction are standard. This tool is installed and used by machinists and tool-and-die professionals in manual and CNC milling setups.

This end mill is suited for roughing and finishing passes on aluminum, brass, copper, and other non-ferrous materials. The long series length makes it appropriate for deeper pockets and extended-reach applications where a standard-length end mill cannot reach. The 1.25-inch shank diameter fits common milling machine collets and end mill holders designed for that shank size. The centercutting capability allows plunge entry directly into the workpiece without a pre-drilled pilot hole.

Key Features

• 2-inch cutting diameter with 4-inch length of cut for deep pocket milling
• M2 high speed steel construction rated for aluminum and non-ferrous materials
• 37-degree helix angle promotes efficient chip flow and reduces heat buildup
• Centercutting design allows direct plunge entry into the workpiece
• Long-series OAL of 6.5 inches supports extended-reach milling setups
• Bright, uncoated finish — no coating to delaminate on softer metals

Compatibility

Designed for use in milling machines and machining centers accepting a 1.25-inch shank diameter end mill holder or collet. Primary workpiece material compatibility is aluminum and non-ferrous metals per the manufacturer material code N classification.

Installation Notes

Installation is performed by a machinist or tooling technician. The machine spindle must be fully stopped and locked out before changing tooling. Verify collet or end mill holder bore matches the 1.25-inch shank diameter before seating the tool. Torque the retention hardware to the machine tool manufacturer specifications and confirm runout with a dial indicator before beginning the cut.
