Value Collection 720-3411 Square End Mill 3/4 in 4 Flute Hss

Product Description

The VALUE COLLECTION 720-3411 is a single-end square end mill designed for milling, slotting, and profiling operations on a wide range of ferrous and non-ferrous materials. Built from M2 high speed steel with a bright uncoated finish, it measures 0.75 inches in diameter with a 4-inch length of cut and a 6.25-inch overall length. The 4-flute, 30-degree spiral helix geometry provides efficient chip evacuation and smooth cutting action. Center-cutting capability allows direct plunging into workpieces without a pre-drilled entry point. This tool is installed and used by machinists and tool-and-die professionals working on manual or CNC milling equipment.

This end mill is suited for general-purpose milling applications in job shop, toolroom, and production environments. The extra-long length type makes it well-suited for deep-pocket milling, reaching into cavities where standard-length end mills fall short. Right-hand cut and right-hand flute orientation match the configuration of conventional vertical and horizontal milling machines. The uncoated M2 HSS construction performs reliably on mild steel, aluminum, brass, and similar materials at moderate cutting speeds.

Key Features

• M2 high speed steel construction for durability across a broad range of workpiece materials
• 4-inch length of cut supports deep-pocket and extended-reach milling operations
• 4 spiral flutes with 30-degree helix angle for balanced chip load and surface finish
• Center-cutting design allows direct plunge entry without pre-drilling
• Bright uncoated finish suitable for use with cutting fluids or dry cutting on non-ferrous materials
• Single-end configuration with 0.75-inch shank diameter for secure toolholder grip

Compatibility

Designed as an OEM-style replacement or direct-use end mill compatible with standard 3/4-inch collets, end mill holders, and side-lock holders used on manual and CNC vertical milling machines.

Installation Notes

Installation is performed by machinists using standard end mill holders or collet chucks rated for 0.75-inch shank diameters. Ensure the milling spindle is fully powered down and locked out before changing tooling. Confirm shank seating depth meets the toolholder manufacturer minimum engagement specification before tightening. Follow machine tool manufacturer guidelines and applicable shop safety procedures when setting feeds, speeds, and depth of cut.
