Value Collection 723-3654 Cobalt Square End Mill 1/8 in

Product Description

The VALUE COLLECTION 723-3654 is a cobalt square end mill designed for precision milling operations in metal fabrication and machining applications. Built from M42 cobalt high-speed steel, this stub-length single-end tool features a 1/8 inch cutting diameter and a 3/16 inch length of cut. The three-flute spiral geometry with a 30-degree helix angle promotes efficient chip evacuation while maintaining a strong cutting edge. The bright, uncoated finish makes it well suited for non-ferrous metals, steels, and alloys where coating buildup is a concern. Machinists and tool-and-die professionals rely on stub-length end mills like this for rigidity in tight-clearance setups where minimizing deflection is critical.

This end mill fits standard milling machines, CNC machining centers, and manual knee mills that accept a 1/4 inch shank. The stub length type and 1.09375 inch overall length make it particularly useful for shallow-pocket milling, slotting, and profiling in applications where tool overhang must be minimized. It is center-cutting, allowing plunge entry directly into the workpiece without a pre-drilled pilot hole. Right-hand cutting and right-hand flute direction are standard for conventional and climb milling on most vertical mill setups.

Key Features

• M42 cobalt construction for improved heat and wear resistance compared to standard M2 HSS
• Three-flute spiral design with 30-degree helix angle for balanced chip load and smooth cutting action
• Center-cutting geometry allows direct plunge entry into the workpiece
• Stub length type reduces deflection and improves rigidity in shallow-reach applications
• Bright, uncoated finish compatible with a wide range of materials and cutting fluids
• Right-hand cut and right-hand flute direction for use in standard milling machine spindles

Compatibility

Designed for use in any milling machine or machining center with a 1/4 inch collet, end mill holder, or compatible tool holder. Part of the Series VCCC-C-3 stub-length cobalt end mill line.

Installation Notes

Installation is performed by a machinist or toolroom professional using a compatible collet or end mill holder torqued to the machine manufacturer's specification. Ensure the spindle is fully powered down and locked before changing tooling. Confirm shank diameter matches the collet or holder bore before seating. Inspect the cutting edges for chips or damage prior to each use, as cobalt tooling can be brittle if impacted or dropped.
