Value Collection 723-6486 Corner Rounding End Mill

Product Description

The Value Collection 723-6486 is a single-end corner rounding end mill designed for machining radius profiles on workpiece edges. Built from M42 cobalt high-speed steel, this tool handles interrupted cuts and harder materials where standard HSS end mills wear prematurely. It carries a 19/64-inch corner radius and a 1-1/8-inch cutting diameter with four right-hand flutes and a right-hand cutting direction. The bright, uncoated finish suits applications where a base substrate is preferred or where re-sharpening is anticipated. Machinists and toolroom operators use this tool on manual mills and CNC machining centers for edge-rounding and radius milling operations.

This corner rounding end mill is suited for use in job shops, production machine shops, and toolroom environments. It is appropriate for rounding edges on steel, alloy steel, cast iron, and similar ferrous materials where M42 cobalt provides sufficient heat and wear resistance. The 3/4-inch shank diameter fits standard R8, CAT, BT, and direct-mount collet toolholders commonly found on vertical knee mills and vertical machining centers. Single-end construction means the tool is used from one end only.

Key Features

• M42 cobalt high-speed steel construction for improved hot hardness over standard M2 HSS
• 19/64-inch corner radius for consistent edge-rounding profiles
• 1-1/8-inch mill diameter with 4 flutes for balanced material removal and chip evacuation
• Right-hand cut and right-hand flute geometry for conventional milling setups
• 3/4-inch shank diameter for compatibility with common toolholder systems
• Bright, uncoated finish — suitable for re-sharpening or use without coating requirements

Compatibility

Designed as an OEM-style replacement or standard toolroom end mill for use in any milling machine or machining center that accepts a 3/4-inch straight shank end mill holder or collet.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Secure the 3/4-inch shank in a properly sized collet or end mill holder and torque the drawbar or retention system per the machine manufacturer's specification. Ensure the machine spindle is fully stopped and locked out before tool changes. Verify runout with a dial indicator before taking finish passes, and select feeds and speeds appropriate for cobalt tooling and the workpiece material being machined.
