Value Collection 720-3332 Square End Mill 1-1/4 in 6 Fl Hss

Product Description

The VALUE COLLECTION 720-3332 is a single-end square end mill designed for milling flat surfaces, shoulders, slots, and profiles in metal and general-purpose machining applications. Built from M2 high speed steel with a bright, uncoated finish, this tool offers a 1.25 inch cutting diameter and a 4 inch length of cut, making it well suited for deep-reach material removal where standard-length end mills fall short. The 6-flute geometry supports higher feed rates and improved surface finish in ferrous and non-ferrous materials. At 6.5 inches overall length, this long-series end mill fits setups where extended reach is required without switching to a custom toolholder.

This end mill is intended for use in vertical machining centers, knee mills, and manual milling machines found in job shops, maintenance departments, and production environments. The right-hand cut, right-hand spiral flute configuration with a 30-degree helix angle is a standard setup compatible with conventional CNC and manual spindle rotation. Centercutting capability allows direct plunge entry into the workpiece where required. This tool is appropriate for machinists working in steel, aluminum, cast iron, and similar materials in both short-run and production contexts.

Key Features

• M2 high speed steel construction for durability across a broad range of workpiece materials
• 6 spiral flutes with a 30-degree helix angle for efficient chip evacuation and improved surface finish
• 4 inch length of cut provides deep-reach capability for slots and stepped features
• Centercutting design allows direct plunge milling without a pre-drilled pilot hole
• Bright, uncoated finish — compatible with cutting fluids and coolant-applied setups
• Long-series length at 6.5 inches OAL extends reach beyond standard-length tooling

Compatibility

Designed as a standard single-end square end mill with a 1.25 inch straight shank, compatible with ER collet chucks, end mill holders, and side-lock holders accepting a 1-1/4 inch shank diameter on CNC machining centers and manual knee mills.

Installation Notes

Installation of this end mill should be performed by a qualified machinist following shop safety procedures. Power down and lock out the spindle before loading or removing the tool. Ensure the shank is fully seated and the retention hardware is properly torqued to the toolholder manufacturer's specification. Verify spindle runout after installation to prevent premature tool wear or workpiece damage.
