Value Collection 723-6441 Corner Rounding End Mill 3/4 in

Product Description

The VALUE COLLECTION 723-6441 is a single-end corner rounding end mill designed to machine radiused edges and contoured profiles on metal workpieces. Built from M42 cobalt high-speed steel, it delivers heat resistance and hardness retention suited for cutting ferrous metals, stainless steel, and other tough alloys. The 4-flute geometry balances chip evacuation with surface finish quality. With a 3/4-inch cutting diameter and an 11/64-inch radius, this tool produces consistent, smooth corner profiles in a single pass. The bright, uncoated finish makes it a cost-effective option for general-purpose contouring and edge-breaking operations in production and job-shop environments.

This end mill is used in vertical machining centers, CNC mills, and manual knee mills for radiusing exterior edges on steel, cast iron, and similar materials. It is appropriate for applications where a controlled corner radius is required for part fit-up, fatigue resistance, or finishing standards. The 1/2-inch shank diameter fits standard R8, CAT, BT, and collet-style tool holders commonly found in machine shops. Machinists and tool-and-die professionals are the primary users of this tooling.

Key Features

• M42 cobalt HSS construction for heat and wear resistance in tough alloy cutting
• 11/64-inch corner radius for consistent, repeatable edge profiling
• 4-flute design balances material removal rate with surface finish
• Right-hand cut and right-hand flute direction for standard spindle operation
• Bright/uncoated finish for general-purpose use without coating-related regrind concerns
• Single-end configuration for dedicated corner rounding operations

Compatibility

Designed as an OEM-style replacement corner rounding end mill for use in any machine tool accepting a 1/2-inch shank diameter, including vertical mills, CNC machining centers, and manual milling machines.

Installation Notes

Installation is performed by qualified machinists familiar with rotating cutting tool safety. Secure the 1/2-inch shank firmly in a clean, properly sized collet or end mill holder before operation, and verify runout with an indicator before cutting. Always power down and lock out the spindle before changing tooling. Do not exceed the tool manufacturer recommended feeds and speeds for the workpiece material being cut.
