Value Collection 723-6429 Corner Rounding End Mill

Product Description

The VALUE COLLECTION 723-6429 is a single-end corner rounding end mill designed to produce consistent radius profiles on workpiece edges in milling operations. Built from M42 cobalt high-speed steel, this tool handles interrupted cuts and harder materials better than standard M2 HSS tooling. It carries a 1/8 inch corner radius and a 5/8 inch cutting diameter across 4 right-hand flutes, delivering smooth edge rounding on steel, stainless, cast iron, and similar ferrous materials. The bright, uncoated finish makes tool wear easy to monitor during service. Machinists and toolroom operators use this end mill in manual knee mills and CNC machining centers alike.

This corner rounding end mill is suited for production and toolroom work where a consistent 1/8 inch radius edge profile is required. It fits standard milling setups with a 1/2 inch shank diameter and an overall length of 3 inches, making it compatible with common collet chucks and end mill holders found on vertical milling machines and machining centers. The right-hand cutting direction and right-hand flute helix suit standard spindle rotation without modification.

Key Features

• M42 cobalt HSS construction for improved heat and wear resistance over standard HSS grades
• 1/8 inch corner radius for precise, repeatable edge profiling
• 4 right-hand flutes with right-hand cutting direction for smooth chip evacuation
• Bright, uncoated finish allows visual inspection of tool wear
• Single-end design with 1/2 inch shank diameter for secure toolholder engagement
• 3 inch overall length suits standard milling setups without extended reach concerns

Compatibility

Designed as an OEM-style replacement or standard production tool for milling applications requiring a 1/2 inch shank, 5/8 inch diameter corner rounding end mill with a 1/8 inch radius profile.

Installation Notes

Installation is performed by a machinist or toolroom operator using a compatible end mill holder or collet chuck rated for 1/2 inch shank tooling. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Confirm runout with a dial indicator after seating the tool, as excessive runout accelerates edge wear on corner rounding profiles. Follow the machine manufacturer and tooling supplier feed and speed recommendations for the specific workpiece material.
