Harvey Tool 945160-C3 Corner Radius End Mill 5/16 in

Product Description

The HARVEY TOOL 945160-C3 is a solid carbide corner radius end mill designed for precision milling in demanding shop environments. With a 5/16-inch diameter, a 0.06-inch corner radius, and an AlTiN (aluminum titanium nitride) PVD coating, this tool handles both roughing and finishing operations across a wide range of workpiece materials. The single-end, 4-flute configuration with a right-hand helical flute geometry promotes efficient chip evacuation and consistent surface finish. Overall length is 2.5 inches with a 5/16-inch straight cylindrical shank. This tool is installed and operated by machinists and CNC technicians working in production and job-shop settings.

This end mill is suited for milling steel, stainless steel, cast iron, non-ferrous metals, and composite materials. It belongs to the Harvey Tool Miniature End Mills - Corner Radius - Stub and Standard series, making it appropriate for applications where a small-diameter, corner-radius profile is required — such as slotting, profiling, and pocket milling in tight geometries. The 1-inch length of cut provides adequate reach for standard-depth passes without sacrificing rigidity. It is a center-cutting design, allowing plunge entry where the application requires it.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• AlTiN PVD coating improves heat resistance and extends tool life in ferrous and stainless applications
• 0.06-inch corner radius with a tolerance of plus 0.001 inch to minus 0.001 inch for consistent edge geometry
• Center-cutting design permits direct plunge entry
• Right-hand cut, right-hand helical flutes with normal pitch for smooth chip flow
• Single-end configuration with straight cylindrical shank for standard toolholder compatibility

Compatibility

Designed for use with standard CNC milling toolholders accepting a 5/16-inch straight cylindrical shank. Suitable for machining steel, stainless steel, cast iron, non-ferrous metals, and composite workpiece materials as specified by the manufacturer.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Secure the shank fully into a compatible toolholder and verify runout before cutting. Ensure the machine spindle is at a full stop before tool changes. Follow the machine tool manufacturer and cutting tool manufacturer guidelines for speeds, feeds, and depth of cut for the specific workpiece material.
