Accupro 315359 Corner Radius End Mill 1/8 in 3 Flute

Product Description

The ACCUPRO 315359 is a solid carbide corner radius end mill designed for precision milling operations where edge integrity and tool life are critical. It features a 1/8 inch cutting diameter, a 1/4 inch length of cut, and a ZrN (zirconium nitride) coating that reduces friction and improves wear resistance. The three-flute, right-hand spiral design with a 37-degree helix promotes efficient chip evacuation and smooth cutting action. With a total overall length of 1-1/2 inches and an extended reach configuration, this end mill is suited for machinists and toolmakers working in tight geometries and detailed contouring applications.

This end mill is intended for use in CNC machining centers and manual mills where corner radius geometry is required to produce blended, radiused edges on workpieces. The extended reach and reduced neck diameter of 0.1188 inches make it well suited for accessing recessed features and stepped pockets. It is a single-end, centercutting tool, meaning it can be plunged directly into material. Typical users include precision machinists, tool-and-die makers, and production shop operators working with ferrous and non-ferrous metals and alloys where a micrograin carbide substrate is appropriate.

Key Features

• ZrN coating reduces friction and extends tool life in demanding cutting conditions
• Micrograin solid carbide substrate provides rigidity and edge sharpness
• 3-flute, right-hand spiral with 37-degree helix for efficient chip removal
• Centercutting geometry allows direct plunge entry into the workpiece
• Extended reach design with 1/2 inch reach length for accessing deep or recessed features
• Corner radius of 0.0300 inches blends sharp transitions and reduces stress concentration at part edges

Compatibility

Designed as a standard 1/8 inch shank corner radius end mill for use in collet-style and end mill holders compatible with 1/8 inch shank tooling on CNC or manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following the tool holder manufacturer's torque and runout specifications. Ensure the shank is fully seated in the collet or end mill holder and that the machine spindle is completely stopped before tool changes. Inspect the cutting edges and coating for chips or wear before each use. Follow applicable shop safety standards and machine guarding requirements during setup and operation.
