Helical Solutions 82012 Corner Radius End Mill 3/8 in 3 Flute

Product Description

The HELICAL SOLUTIONS 82012 is a single-end, corner radius end mill designed for high-performance material removal in aluminum and non-ferrous metal applications. Built from solid carbide with a Zplus PVD coating, this tool features a 3/8-inch diameter, a 0.0600-inch corner radius, and three flutes with a variable pitch and medium helix angle. The chipbreaker geometry supports efficient chip evacuation during roughing operations. At 3 inches overall length with a 1-inch length of cut, it fits standard milling setups and is compatible with high-precision toolholders. Licensed machinists and CNC operators install this tooling in both job shop and production environments.

This end mill is engineered primarily for aluminum and non-ferrous metals, with secondary capability in steel, stainless steel, cast iron, high-temperature alloys, and hard materials. The H35ALV-C-3 series targets applications requiring controlled corner radius geometry and consistent surface finish in roughing passes. The 3/8-inch straight-cylindrical shank fits collet chucks and end mill holders sized for high-precision toolholding. It is centercutting, allowing plunge entry where required by the machining operation.

Key Features

• Solid carbide construction for rigidity and wear resistance in aggressive cuts
• Zplus PVD coating optimized for aluminum and non-ferrous metal machining
• 0.0600-inch corner radius with tolerance of -0.0020 to +0.0020 inches for consistent finish geometry
• Variable pitch fluting reduces harmonic chatter during roughing passes
• Chipbreaker geometry promotes chip evacuation and reduces recutting
• Centercutting design permits plunge milling entry
• Right-hand cut, right-hand flute spiral with straight-cylindrical shank for broad toolholder compatibility

Compatibility

Designed for use with high-precision toolholders. Primary workpiece material is aluminum and non-ferrous metal; secondary materials include steel, stainless steel, cast iron, high-temperature alloys, and hard materials. Part of the H35ALV-C-3 series.

Installation Notes

Installation and tool changes should be performed by qualified machinists with the spindle fully stopped and machine in a safe, locked-out state. Seat the shank fully into a clean, properly sized collet or end mill holder and torque the retention hardware per the toolholder manufacturer's specification. Verify runout against the stated maximum TIR of 0.0003 inches before production cuts. Do not exceed the toolholder's rated speed or the cutting parameters recommended for the workpiece material and coating type.
