Accupro 315654 Corner Radius End Mill 3/4 in Zrn Carbide

Product Description

The ACCUPRO 315654 is a solid micrograin carbide corner radius end mill designed for precision milling operations in ferrous and non-ferrous materials. It features a 3/4 inch mill diameter, a 1 inch length of cut, and a 5 inch overall length with a 2.5 inch extended reach. The ZrN (zirconium nitride) coating increases surface hardness and reduces friction at the cutting edge, extending tool life in production environments. With three right-hand spiral flutes and a 37-degree helix angle, this end mill provides efficient chip evacuation and smooth finishes. It is centercutting, allowing plunge entry without a pre-drilled hole.

This end mill is suited for CNC machining centers and manual mills where a corner radius profile is required to blend floor and wall transitions without sharp internal corners. The 0.030 inch corner radius reduces stress concentrations in milled pockets and slots. The extended reach neck diameter of 0.7125 inches allows access to deeper features while maintaining rigidity. Typical applications include mold and die work, aerospace component machining, and general precision part production where tight tolerances and a fine surface finish are required.

Key Features

• ZrN coating for improved wear resistance and reduced built-up edge
• Solid micrograin carbide construction for rigidity and edge retention
• 0.030 inch corner radius reduces stress risers in milled pockets and contours
• Centercutting design allows direct plunge entry
• Extended reach of 2.5 inches for access to deeper features
• Three right-hand flutes with 37-degree helix for efficient chip evacuation

Compatibility

Designed as a standard 3/4 inch shank corner radius end mill compatible with CNC machining centers, knee mills, and other milling machines accepting 3/4 inch straight shank toolholders, collet chucks, or end mill holders.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Secure the shank fully within the toolholder to the recommended minimum engagement depth per the toolholder manufacturer before torquing. Verify runout with a dial indicator before beginning a production cut. Do not exceed the rated cutting parameters for the workpiece material; consult the manufacturer feed and speed charts for ZrN-coated carbide tooling.
