Value Collection 723-1059 Cobalt Square End Mill 11/16 in

Product Description

The VALUE COLLECTION 723-1059 is a 2-flute cobalt square end mill designed for material removal and profiling in demanding machining applications. Built from M42 cobalt high-speed steel, it delivers the heat and wear resistance needed when cutting steel, stainless steel, cast iron, and high-temperature alloys. The mill features an 11/16-inch cutting diameter, a 1-5/16-inch length of cut, and a 3-7/16-inch overall length. A bright, uncoated finish keeps the tool ready for direct use without additional prep. It is a single-end, right-hand cut and right-hand helix tool with a 30-degree helix angle and center-cutting capability, making it suitable for plunge entries as well as peripheral cuts.

This end mill is used in manual mills and CNC machining centers handling ferrous metals and high-temperature alloys. Its 5/8-inch shank diameter fits standard collets and end mill holders in that size range. The regular-length designation and 2-flute geometry make it well suited for slotting, profiling, and step milling in materials that demand cobalt-grade tooling over standard HSS. Machinists and toolroom operators working in job shops, maintenance facilities, and production environments will find this tool appropriate for general-purpose ferrous cutting where heat buildup is a concern.

Key Features

• M42 cobalt high-speed steel construction for improved red hardness in ferrous and high-temp alloy cuts
• Center-cutting geometry allows direct plunge entry without pre-drilled pilot holes
• 30-degree right-hand spiral helix promotes chip evacuation and reduces chatter
• Bright, uncoated finish compatible with most cutting fluids and coolant strategies
• 2-flute design optimizes chip clearance in slotting and full-width cuts
• Single-end configuration with 5/8-inch shank for standard collet or end mill holder mounting

Compatibility

Designed for use in milling operations on steel, stainless steel, cast iron, and high-temperature alloys. Compatible with any milling machine or machining center equipped with a 5/8-inch collet, end mill holder, or Weldon-style tool holder.

Installation Notes

Installation and tool changes should be performed with the machine powered off and fully at rest. Secure the 5/8-inch shank firmly in a properly sized collet or end mill holder to the torque specified by the toolholder manufacturer. Verify runout with a dial indicator before cutting to maximize tool life and surface finish. Always use appropriate cutting fluid or coolant for the workpiece material.
