Harvey Tool 56550-C3 Corner Radius End Mill 6mm 3 Flute Carbide

Product Description

The HARVEY TOOL 56550-C3 is a solid carbide corner radius end mill designed for high-performance milling across a wide range of workpiece materials. The cutter features a 6 mm (0.236 inch) mill diameter, a 1/16 inch (0.062 inch) corner radius, and three right-hand spiral flutes with a high helix angle. An AlTiN PVD coating provides thermal and wear resistance, making this tool well suited for both roughing and finishing operations. The 1/4 inch straight cylindrical shank mounts directly into standard toolholders, and the single-end configuration keeps the setup straightforward for machining centers and manual mills alike.

This end mill is built for use in steel, stainless steel, cast iron, non-ferrous metals, and composite materials. It fits into Harvey Tool's Dovetail Cutters and O-Ring Slotting End Mills specialty profile series, making it a practical choice for machinists who need a short-length corner radius profile cutter that can handle both finish passes and light material removal in a single tool. The center-cutting geometry allows plunge entry where needed, and the normal pitch flute spacing suits general shop applications on CNC machining centers.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous and non-ferrous materials
• AlTiN PVD coating reduces heat buildup and extends tool life in steel and stainless steel
• Corner radius of 0.062 inches with a tight tolerance of plus or minus 0.001 inches
• Center-cutting, right-hand flute direction allows direct plunge entry
• High helix, three-flute spiral geometry supports both roughing and finishing in a single pass
• Short length-of-cut profile minimizes deflection in tight clearance applications

Compatibility

Designed for use with standard toolholders accepting a 1/4 inch straight cylindrical shank. Part of the Harvey Tool Dovetail Cutters and O-Ring Slotting End Mills series as well as the Specialty Profiles series.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Ensure the machine spindle is fully powered down and the toolholder is clean and free of debris before seating the shank. Confirm runout with a dial indicator after clamping, as corner radius tools are sensitive to runout-induced chipping. Do not exceed the recommended depth of cut for the workpiece material and cutter diameter combination specified in Harvey Tool's published feed and speed data.
