Harvey Tool 56520-C3 Corner Radius End Mill 0.085in 3 Flute

Product Description

The HARVEY TOOL 56520-C3 is a solid carbide corner radius end mill designed for precision milling in ferrous and non-ferrous materials. It measures 0.085 inches in diameter with a 1/64 inch (0.015 inch) corner radius and features a 3-flute, right-hand spiral geometry with a high helix angle of 35 degrees. AlTiN PVD coating extends tool life when cutting steel, stainless steel, and cast iron. The single-end configuration and short flute length make it well suited to tight-tolerance slotting and profiling operations. Licensed machinists and CNC programmers working with tight geometries and small-diameter tooling will find this cutter appropriate for close-tolerance applications.

This end mill is part of the Harvey Tool Dovetail Cutters and O-Ring Slotting End Mills specialty profile series. It is suited for use in CNC machining centers and manual mills with compatible straight-shank toolholders. Primary workpiece materials include steel, stainless steel, cast iron, non-ferrous metals, and composite materials. The center-cutting design allows plunge entry, and the short flute length supports rigidity in demanding roughing and finishing passes on small features.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN PVD coating rated for steel, stainless steel, and cast iron applications
• 3-flute, right-hand spiral geometry with 35-degree high helix for efficient chip evacuation
• Center-cutting design allows direct plunge entry
• 0.015 inch corner radius reduces stress concentration at the cutting edge
• Straight cylindrical shank compatible with standard toolholders
• Capable of both roughing and finishing material removal in a single tool

Compatibility

Designed for use with standard straight-shank toolholders. Suitable for steel, stainless steel, cast iron, non-ferrous metals, and composite workpiece materials per ISO material groups P, M, K, N, and O.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the toolholder. Confirm runout and tool projection are within acceptable limits before beginning a cut. Do not exceed the recommended depth of cut for the tool diameter, and use appropriate cutting fluid or air blast where coolant-through is not available.
