Value Collection 723-3903 Square End Mill 1/2 in 4 Flute

Product Description

The VALUE COLLECTION 723-3903 is a cobalt square end mill designed for single-end milling operations in metalworking and machining applications. Built from M42 cobalt high-speed steel, it delivers hardness and heat resistance suited to cutting ferrous and non-ferrous materials at elevated feed rates. The cutter measures 1/2 inch in diameter with a 1 inch length of cut and a 2-11/16 inch overall length. Four spiral flutes with a 30-degree helix angle promote chip evacuation and surface finish quality. The bright, uncoated finish suits general-purpose applications where coating is not required. Machinists and tool-and-die professionals install this end mill in manual mills, CNC machining centers, and knee mills.

This end mill is suited for peripheral and slot milling in job shop, production, and maintenance environments. The 3/8 inch shank diameter fits standard collets and end mill holders common to vertical milling machines and CNC machining centers. The regular-length geometry and single-end configuration make it a practical choice for face milling, profiling, and shallow pocket cutting in steel, stainless steel, cast iron, and similar materials. Its center-cutting capability allows plunge entry directly into the workpiece without a pre-drilled pilot hole.

Key Features

• M42 cobalt construction provides heat resistance and wear life in tough materials
• 4 spiral flutes with 30-degree helix for efficient chip removal and finish quality
• Center-cutting design allows direct plunge cuts without a pilot hole
• Bright uncoated finish suitable for general-purpose applications
• Right-hand cut and right-hand flute direction for standard spindle rotation
• Regular-length profile offers rigidity for slotting and profiling operations

Compatibility

Designed as a general-purpose replacement or stock end mill for use with standard 3/8 inch collets and end mill holders on vertical mills and CNC machining centers accepting fractional inch tooling.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Ensure the spindle is fully stopped and locked before seating or removing the end mill from the collet or holder. Use a calibrated torque wrench and appropriate collet nut wrench when tightening the holder to prevent runout. Inspect the shank for damage or burrs before installation, and confirm correct tool projection length for the intended cut depth.
