Value Collection 723-3662 Square End Mill 1/4 in Cobalt 3 Flute

Product Description

The VALUE COLLECTION 723-3662 is a cobalt square end mill designed for precision milling operations in metal fabrication and machining environments. Built from M42 cobalt high-speed steel, it delivers superior heat resistance and edge retention compared to standard HSS tooling. The stub-length configuration offers added rigidity, reducing deflection during aggressive cuts. With a 1/4 inch mill diameter, 3/8 inch length of cut, and a 30-degree helix angle, this end mill is suited for slotting, profiling, and peripheral milling on ferrous and non-ferrous materials. It is installed and operated by machinists and tool-and-die professionals in both manual and CNC milling setups.

This end mill is a single-end, center-cutting tool with right-hand cutting and right-hand flute direction, making it compatible with standard right-hand spindle milling machines and machining centers. The stub-length body and 1/4 inch shank diameter make it particularly useful in tight-clearance setups where a longer reach end mill would introduce chatter or deflection. Typical applications include side milling, full-slot cutting, and step milling in steel, stainless steel, cast iron, and similar materials.

Key Features

• M42 cobalt material grade for extended tool life in harder workpiece materials
• 3 flutes with spiral right-hand flute direction for efficient chip evacuation
• 30-degree helix angle balances cutting efficiency with edge strength
• Center-cutting design allows plunge entry into workpiece
• Bright/uncoated finish suitable for use with or without cutting fluids
• Stub length reduces overhang and improves rigidity in close-clearance setups

Compatibility

Designed as an OEM-style replacement or standard tooling option for 1/4 inch collet chucks, end mill holders, and milling arbors on conventional and CNC vertical milling machines accepting a 1/4 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following standard toolroom procedures. Ensure the milling machine spindle is fully stopped and locked before inserting or removing the end mill from its holder. Secure the shank to the recommended engagement depth in the collet or end mill holder to prevent pullout under load. Do not exceed the tool manufacturer's recommended feed and speed parameters for the workpiece material and depth of cut.
