Value Collection 723-6525 Corner Rounding End Mill

Product Description

The VALUE COLLECTION 723-6525 is a single-end corner rounding end mill designed to machine smooth, consistent radius profiles on workpiece edges. Built from M42 cobalt high-speed steel, it handles tough ferrous and heat-resistant alloys that challenge standard HSS tooling. The 4-flute configuration provides a good balance of chip clearance and surface finish. With a 7/16-inch radius and a 1-3/8-inch mill diameter, this tool suits machinists and tool-and-die professionals running manual mills or CNC machining centers where edge-break and radius work are common operations.

This corner rounding end mill is suited for job shops, tool rooms, and production environments requiring consistent edge radii on steel, stainless, cast iron, and similar materials. The bright, uncoated finish makes it a straightforward choice for general-purpose corner rounding where a specific coating is not required. The 1-inch shank diameter fits standard ER and end mill holders used in both vertical and horizontal milling setups. It is sold as a single unit.

Key Features

• M42 cobalt steel construction for improved red hardness and wear resistance over standard M2 HSS
• 7/16-inch corner radius for consistent edge profiling
• 4 flutes with right-hand cut and right-hand helix for smooth chip evacuation
• Bright/uncoated finish suitable for general-purpose ferrous milling
• Single-end design with 1-inch shank diameter and 4-inch overall length

Compatibility

Designed as a direct-fit replacement for corner rounding end mills with a 1-inch straight shank, compatible with standard end mill holders and collet chucks accepting 1-inch shank tooling in vertical or horizontal milling machines.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's setup procedures. Ensure the spindle is fully de-energized and the machine is locked out before changing tooling. Seat the shank fully in the holder to the recommended engagement depth and torque the set screws or collet nut per the holder manufacturer's specifications. Inspect the cutting edges for chips or damage before each use.
