Value Collection 720-3117 Square End Mill 6 Flute Hss

Product Description

The VALUE COLLECTION 720-3117 is a single-end square end mill designed for milling flat surfaces, shoulders, slots, and contour profiles on metalworking machining centers and manual mills. Built from M2 high speed steel with a bright uncoated finish, this tool features a 1.1875-inch cutting diameter and six spiral flutes with a 30-degree helix angle. The right-hand cut, right-hand flute geometry produces a smooth cutting action suited for general-purpose ferrous and non-ferrous material removal. It is typically installed by machinists and tool-and-die professionals in production or job-shop environments.

This end mill is configured for regular-length applications where a 2-inch length of cut is sufficient and extended reach is not required. The 0.75-inch shank diameter fits standard ER collet chucks, side-lock holders, and shrink-fit toolholders commonly found in vertical machining centers and knee mills. The 4.25-inch overall length keeps overhang manageable for rigidity. It is a non-centercutting tool, meaning it is not suited for direct plunge cuts into solid material without a pre-drilled entry point.

Key Features

• M2 high speed steel construction for toughness and wear resistance in general machining
• Six flutes for improved surface finish and higher feed rates compared to four-flute designs
• 30-degree helix angle promotes efficient chip evacuation and reduced cutting forces
• Bright uncoated finish suitable for use with cutting fluids on a wide range of materials
• Right-hand cut and right-hand spiral flute geometry for standard milling operations
• Single-end configuration with regular-length geometry for rigid, low-overhang setups

Compatibility

Designed as an OEM-style replacement or direct drop-in end mill for standard 3/4-inch shank toolholding systems used in vertical and horizontal milling applications.

Installation Notes

Installation and tool changes must be performed by qualified machinists with the machine powered off and the spindle fully stopped. Ensure the shank is clean and free of chips or burrs before seating in the toolholder, and torque the retention hardware per the toolholder manufacturer specification. Because this tool is non-centercutting, always use a pre-drilled or pre-bored entry point before engaging radial cuts. Verify runout with a dial indicator after installation to confirm proper seating and minimize premature tool wear.
