Value Collection 723-3417 Square End Mill Cobalt 4 Flute

Product Description

The VALUE COLLECTION 723-3417 is a cobalt square end mill engineered for demanding milling operations where heat resistance and edge retention are critical. Ground from M42 cobalt high-speed steel, this single-end tool features four spiral flutes with a 30-degree helix angle, producing efficient chip evacuation and a smooth cut finish. The extra-long 6-inch length of cut makes it well suited for deep-pocket and deep-slot milling work that standard-length end mills cannot reach. It ships bright and uncoated, ready for use in a wide range of ferrous and non-ferrous materials. Licensed machinists and CNC setup technicians are the primary users of this tool class.

This end mill is designed for use in vertical machining centers, knee mills, and manual milling machines equipped with an appropriate collet or end-mill holder sized to accept a 1.25-inch shank. The extra-long length of cut suits applications including deep-cavity moldwork, aerospace structural components, die machining, and any operation requiring reach beyond what a standard or long-series end mill provides. The right-hand cutting direction and right-hand flute direction are standard for conventional CNC spindle rotation.

Key Features

• M42 cobalt HSS construction provides elevated hot hardness compared to standard M2 high-speed steel
• Four spiral flutes with 30-degree helix angle promote chip evacuation and reduce cutting forces
• Extra-long 6-inch length of cut enables deep-pocket and deep-slot operations
• Centercutting geometry allows plunge milling as well as peripheral and slot cutting
• Bright/uncoated finish is compatible with most cutting fluids and regrinding services
• Single-end design with 1-1/4 inch shank diameter for rigid tool holding

Compatibility

Designed for use in standard end-mill holders, collet chucks, and Weldon-flat set-screw holders accepting a 1-1/4 inch shank diameter. Verify spindle taper and holder bore before installation.

Installation Notes

Installation and tool changes must be performed with the machine spindle at a full stop and the machine control in an e-stop or tool-change state. Use a properly sized end-mill holder or collet rated for the 1-1/4 inch shank diameter and torque the retention fastener according to the holder manufacturer specification. Confirm runout with a dial indicator before taking a first cut. Follow your shop safety plan and applicable OSHA machine guarding requirements when operating milling equipment.
