Helical Solutions 82432 Corner Radius End Mill 3/8 in 3 Flute

Product Description

The HELICAL SOLUTIONS 82432 is a solid carbide corner radius end mill designed for high-performance milling in both roughing and finishing operations. Built to Series H40ALV-3 specifications, it features a 3/8-inch diameter, 2-inch length of cut, and a 0.0600-inch corner radius that reduces stress concentrations at part edges. The Zplus PVD coating is engineered primarily for aluminum and non-ferrous metals, offering lubricity and wear resistance. With three flutes, a variable pitch, and a 40-degree high helix angle, this tool promotes efficient chip evacuation and smooth surface finishes. It is center-cutting and designed for use with high-precision toolholders.

This end mill is suited for CNC machining centers and high-speed milling applications in job shops, production facilities, and aerospace or general metalworking environments. Its primary application is aluminum and non-ferrous metal machining, with secondary capability in steel, stainless steel, cast iron, high-temperature alloys, and hard materials. The straight cylindrical shank and h6 diameter tolerance make it compatible with precision collet chucks and shrink-fit holders. It ships as a single-end tool, one piece per package.

Key Features

• 0.0600-inch corner radius with tolerance of -0.0020 to 0.0020 inches for consistent edge geometry
• Zplus PVD coating optimized for aluminum and non-ferrous metal cutting
• Variable pitch design reduces harmonic chatter during aggressive cuts
• 40-degree high helix angle promotes rapid chip evacuation
• Center-cutting geometry allows plunge entry
• Right-hand flute direction and right-hand cutting for standard CNC spindle use
• Maximum TIR of 0.0003 inches for precision runout control

Compatibility

Designed for use with high-precision toolholders including collet chucks and shrink-fit systems. Primary workpiece material is aluminum and non-ferrous metal (Material Code N); secondary materials include steel, stainless steel, cast iron, high-temperature alloys, and hard materials (Material Codes P, M, S, H). Part of the H40ALV-3 series.

Installation Notes

Installation should be performed by a qualified CNC machinist or tooling technician. Ensure the spindle is fully stopped and the machine is in a safe state before loading or unloading the tool. Use a torque-rated toolholder wrench appropriate to the holder style and follow the toolholder manufacturer's clamping specifications. Verify runout at the tool tip after installation before beginning the cut cycle.
