Value Collection 723-3916 Square End Mill 15/16 in 4 Flute Cobalt

Product Description

The VALUE COLLECTION 723-3916 is a single-end cobalt square end mill designed for milling operations in ferrous and difficult-to-machine materials. Built from M42 cobalt high-speed steel, this tool delivers heat resistance and edge retention in demanding cutting applications. It features a 15/16-inch (0.9375 inch) cutting diameter, a 1-7/8-inch (1.875 inch) length of cut, and a 30-degree helix angle that promotes efficient chip evacuation. The bright, uncoated finish makes it straightforward to inspect for wear. This end mill is installed and operated by machinists and tool-and-die professionals working with manual mills, CNC machining centers, and knee mills.

This end mill suits general-purpose peripheral and slot milling in shop environments where cobalt tooling is selected over carbide for its toughness in interrupted cuts or inconsistent workpiece hardness. The 4-flute configuration provides a good balance of chip clearance and surface finish in steels, alloy steels, stainless, and similar materials. The right-hand cut and right-hand spiral flute direction are standard for conventional milling setups. The center-cutting geometry allows plunge entry as well as lateral passes without a pre-drilled pilot hole.

Key Features

• M42 cobalt HSS construction for improved heat and wear resistance compared to standard M2 tooling
• 4 spiral flutes with right-hand cut and right-hand helix for efficient chip removal
• 30-degree helix angle promotes smooth cutting action and reduces chatter
• Center-cutting design allows plunge milling without a pilot hole
• Bright/uncoated finish — easy visual inspection of cutting edges between passes
• Single-end configuration with 3/4-inch shank diameter for direct collet or end mill holder mounting

Compatibility

Designed as a standard single-end square end mill with a 3/4-inch shank, compatible with collet chucks, end mill holders, and milling machine spindles sized for 3/4-inch straight shanks in manual or CNC milling applications.

Installation Notes

Installation is performed by qualified machinists. Secure the shank fully into a collet or end mill holder and verify runout before cutting. Power down and lock out the spindle before changing tooling. Follow shop safety procedures and applicable OSHA machine guarding requirements when operating milling equipment.
