Helical Solutions 59133 Corner Radius End Mill 1/2 in 3 Flute

Product Description

The HELICAL SOLUTIONS 59133 is a solid carbide corner radius end mill designed for high-performance milling in both roughing and finishing operations. It features a 1/2 inch cutting diameter, a 0.0600 inch corner radius, and a 3-flute spiral flute geometry with a 35-degree medium helix angle. The Zplus PVD coating - a proprietary HELICAL SOLUTIONS finish - provides enhanced lubricity and wear resistance, making this tool well-suited for aluminum and other non-ferrous metals. It is a single-end, centercutting design with right-hand flute direction and right-hand cutting direction. Licensed machinists and CNC tool setup technicians are the primary users of this tool.

This end mill is engineered primarily for aluminum and non-ferrous metal applications, with secondary capability in steel, stainless steel, cast iron, high temperature alloys, and hard materials. It is part of the H35AL-3 series, optimized for use with high precision toolholders. Typical applications include profiling, slotting, and contouring in CNC machining centers where consistent corner geometry and surface finish are required. The coarse pitch geometry supports efficient chip evacuation in non-ferrous cuts.

Key Features

• 0.0600 inch corner radius with tolerance of -0.0020 to 0.0020 inches for consistent edge geometry
• Zplus PVD proprietary coating for improved wear resistance in aluminum and non-ferrous milling
• 3-flute solid carbide construction with 35-degree medium helix for chip control in roughing and finishing
• Centercutting design allows plunge entry cuts
• Right-hand spiral, right-hand cut with straight-cylindrical shank (h6 tolerance) for secure toolholder fit
• TIR maximum of 0.0003 inches for high-precision applications

Compatibility

Designed for use with high precision toolholders. Recommended for CNC machining of aluminum, non-ferrous metals, steel, stainless steel, cast iron, high temperature alloys, and hard materials. Part of the HELICAL SOLUTIONS H35AL-3 series.

Installation Notes

Installation is performed by a CNC machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Use a high-precision toolholder that matches the 1/2 inch straight-cylindrical shank to maintain runout within specification. Verify tool projection and reach before beginning a cut, and confirm the toolholder clamping torque follows the toolholder manufacturer's guidelines.
