Value Collection 723-6528 Corner Rounding End Mill

Product Description

The VALUE COLLECTION 723-6528 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, it offers strong heat and wear resistance suited for cutting harder ferrous and non-ferrous materials. The tool measures 1.375 inches in diameter with a 15/32-inch corner radius and runs a 3/4-inch shank for secure tool holder engagement. Four right-hand flutes with a bright uncoated finish make this a straightforward, general-purpose profiling tool for machine shops and toolrooms.

This corner rounding end mill is used in vertical and horizontal milling machines, CNC machining centers, and manual knee mills. It is suited for edge-breaking, radius profiling, and decorative chamfering on steel, stainless, cast iron, and similar materials. The M42 cobalt grade provides additional red hardness compared to standard M2 HSS, making it a practical choice when cutting higher-alloy or work-hardening steels without moving to carbide tooling. Machinists and tool-and-die professionals are the primary users in both job shop and production environments.

Key Features

• M42 cobalt HSS construction for elevated heat resistance and edge retention
• 15/32-inch corner radius produces a consistent, repeatable profile
• Four right-hand flutes for efficient chip evacuation and smooth surface finish
• 3/4-inch shank diameter fits standard milling collets and end mill holders
• Bright uncoated finish — compatible with most cutting fluids and coolants
• Single-end design; one cutting end per tool

Compatibility

Designed as an OEM-style replacement or direct-use corner rounding end mill for standard milling setups requiring a 3/4-inch shank and a 15/32-inch radius profile.

Installation Notes

Installation is performed by a machinist or toolroom professional using a compatible end mill holder or collet chuck rated for a 3/4-inch shank. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify runout with a dial indicator after seating the shank to minimize vibration and premature edge wear. Use appropriate cutting fluid or coolant for the workpiece material to preserve tool life.
