Helical Solutions 82410 Corner Radius End Mill 1/8 in 3 Flute

Product Description

The HELICAL SOLUTIONS 82410 is a single-end corner radius end mill designed for high-performance milling in aluminum and non-ferrous metals, with secondary capability in steel, stainless steel, cast iron, high-temperature alloys, and hard materials. Built from solid carbide and finished with a Zplus PVD coating, this tool delivers both roughing and finishing material removal in a single pass. It features a 1/8 inch diameter, a 0.0300 inch corner radius, and a 3-flute spiral geometry with variable pitch and a high helix angle of 40 degrees. Licensed machinists and CNC operators working with precision toolholders will find this tool well-suited to tight-tolerance applications.

This end mill belongs to the H40ALV-3 series, optimized primarily for aluminum and non-ferrous metal machining. The variable pitch design reduces harmonic chatter during aggressive cuts. With a 5/8 inch length of cut and 2.5 inch overall length, it fits standard CNC machining centers and manual mills where short-reach, small-diameter work is required. The centercutting geometry allows plunge entry. It is intended for use with high-precision toolholders to maintain the stated TIR maximum of 0.0003 inch.

Key Features

• Solid carbide construction with Zplus PVD coating for extended tool life in aluminum and non-ferrous applications
• 0.0300 inch corner radius with a tight tolerance of -0.0020 to 0.0020 inch for consistent edge geometry
• Variable pitch, 3-flute spiral design reduces chatter and supports both roughing and finishing passes
• 40-degree high helix angle promotes efficient chip evacuation in aluminum and soft metals
• Centercutting end allows direct plunge milling without a pre-drilled entry point
• TIR maximum of 0.0003 inch supports high-precision, close-tolerance machining environments

Compatibility

Designed for use with high-precision toolholders. Primary workpiece material is aluminum and non-ferrous metals; secondary materials include steel, stainless steel, cast iron, high-temperature alloys, and hard materials. Part of the H40ALV-3 series.

Installation Notes

Installation should be performed by a qualified CNC operator or machinist. Ensure the spindle is fully stopped and the machine is in a safe state before loading or changing tooling. Use a high-precision toolholder to maintain runout within the specified TIR and to protect the h6-tolerance shank. Confirm correct tool offset and feed-rate programming before initiating a cut, particularly when plunge milling.
