Value Collection 720-8080 Square End Mill 0.315 in 4 Flute Hss

Product Description

The VALUE COLLECTION 720-8080 is a 4-flute, single-end square end mill machined from M2 high speed steel. It is designed for general-purpose milling operations including slotting, profiling, and peripheral cutting on a wide range of workpiece materials. The cutter measures 0.315 inches in diameter with a 0.75-inch length of cut and a 0.375-inch shank diameter, giving it a compact profile suited for close-tolerance work. The spiral flute geometry at a 30-degree helix angle promotes efficient chip evacuation. The bright, uncoated finish is standard for HSS tooling used across conventional milling applications.

This end mill is suited for use in manual mills, knee mills, and CNC machining centers running at moderate speeds and feeds. The right-hand cut and right-hand flute configuration is the standard orientation for most vertical milling setups. Its centercutting capability allows direct plunge entry into the workpiece without pre-drilling. Machinists in general job shop environments and tool rooms will find this a dependable option for ferrous and non-ferrous material removal at standard cutting parameters.

Key Features

• M2 high speed steel construction for durability across a range of workpiece materials
• 4-flute design provides a good balance of chip clearance and surface finish quality
• Centercutting geometry allows direct plunge milling without a pilot hole
• 30-degree helix angle supports smooth chip flow and reduced cutting forces
• Bright uncoated finish suitable for use with standard cutting fluids
• Right-hand cut and right-hand flute — standard orientation for most milling setups

Compatibility

Designed as a standard single-end square end mill with a 0.375-inch shank, compatible with conventional ER collets, end mill holders, and milling chucks sized for 3/8-inch shanks in vertical milling machines and CNC machining centers.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a safe, locked-out state. Ensure the collet or tool holder is clean and free of debris before seating the shank to the correct insertion depth. Torque the retention mechanism to the tool holder specification. Verify runout with a dial indicator before beginning a cut to confirm proper seating.
