Value Collection 723-3203 Square End Mill 3/16in Cobalt

Product Description

The VALUE COLLECTION 723-3203 is a cobalt square end mill designed for metal removal in milling applications. Built from M42 cobalt high-speed steel, it offers greater heat and wear resistance than standard HSS tooling, making it well-suited for harder ferrous materials and interrupted cuts. The 3/16 inch cutting diameter and 1/2 inch length of cut make it a compact, precise tool for slotting, profiling, and peripheral milling. A 30-degree right-hand spiral with four flutes promotes chip evacuation and surface finish quality. The bright, uncoated finish is appropriate for applications where coating adhesion or workpiece contamination is a concern.

This end mill is used in manual and CNC milling operations across job shops, tool rooms, and maintenance environments. The 3/16 inch diameter suits fine detail work, narrow slot cutting, and contour milling on steel, stainless, cast iron, and similar materials. The 3/8 inch shank diameter fits standard collets and end mill holders common in both knee mills and machining centers. Its single-end configuration is standard for general-purpose toolroom and production use.

Key Features

• M42 cobalt construction for improved heat resistance and tool life in harder materials
• 4-flute right-hand spiral geometry for efficient chip removal and smooth surface finish
• 30-degree helix angle balances cutting efficiency with lateral force management
• Centercutting design allows plunge entry into workpiece material
• Bright/uncoated finish suitable for dry cutting and coolant-free applications
• Single-end, regular-length configuration for standard milling setups

Compatibility

Designed as a standard fractional-inch shank end mill compatible with 3/8 inch collets and end mill holders used in manual knee mills and CNC machining centers.

Installation Notes

Installation should be performed by a qualified machinist. Secure the shank fully in a collet or end mill holder and verify runout before cutting. Power down and lock out the spindle before changing tooling. Follow machine manufacturer guidelines for feed rate and spindle speed based on workpiece material and depth of cut.
