Value Collection 723-4348 Square End Mill 5/32 in 4 Flute Cobalt

Product Description

The VALUE COLLECTION 723-4348 is a cobalt square end mill designed for metal removal in milling operations performed by machinists and tool-and-die professionals. Built from M42 cobalt high-speed steel, this double-end tool delivers a 5/32 inch (0.1563 inch) cutting diameter with a 7/8 inch (0.8750 inch) length of cut. The 30-degree spiral flute geometry promotes efficient chip evacuation and smooth cutting action. The bright uncoated finish is standard for cobalt tooling used across a wide range of ferrous and non-ferrous workpiece materials. At 3-1/4 inch overall length, this long-series end mill suits applications requiring extended reach beyond standard-length tooling.

This end mill is suited for manual milling machines and CNC machining centers in job shop, maintenance, and production environments. The centercutting design allows plunge entry directly into the workpiece without a pre-drilled pilot hole, expanding its use in slot milling, pocket milling, and contouring operations. The 3/16 inch shank diameter fits standard collets and end mill holders. The double-end configuration provides two usable cutting ends, extending tool life per unit. It is sold individually and is well-suited for low-volume or precision work where exact tool geometry is required.

Key Features

• M42 cobalt construction for heat resistance and edge retention in tough materials
• Double-end design provides two cutting ends per tool
• Centercutting capability allows direct plunge milling without a pilot hole
• 30-degree helix angle promotes chip flow and reduces cutting forces
• Long-series length of 3-1/4 inches overall for extended reach applications
• Bright uncoated finish compatible with a broad range of cutting fluids and materials

Compatibility

Designed as a direct-fit replacement or general-use end mill for standard 3/16 inch collets and end mill holders on manual knee mills and CNC vertical machining centers. No specific OEM model compatibility was provided in the product data.

Installation Notes

Installation is performed by qualified machinists or toolroom professionals. Secure the 3/16 inch shank fully in the collet or end mill holder to the recommended engagement depth before locking down. Verify spindle runout before cutting to protect the tool and workpiece. Always bring spindle speed and feed rate to zero before changing tooling.
