Helical Solutions 82126 Corner Radius End Mill 3/8 in 3 Flute

Product Description

The HELICAL SOLUTIONS 82126 is a solid carbide corner radius end mill designed for high-performance material removal in aluminum and non-ferrous metal applications. With a 3/8-inch mill diameter, 1-inch length of cut, and a 0.0100-inch corner radius, this single-end tool delivers controlled edge geometry for finishing and semi-finishing passes. The 3-flute, right-hand spiral configuration is paired with a variable index pitch and Zplus PVD coating, making it well-suited for demanding CNC milling operations where tool life and surface finish consistency are critical. This tool is centercutting, enabling direct plunge entry. It is used primarily by machinists and CNC operators in production and job shop environments.

The 82126 is optimized for primary use in aluminum and non-ferrous metals, with secondary capability in steel, stainless steel, cast iron, high-temperature alloys, and hard materials. The Zplus coating is engineered to reduce built-up edge in sticky non-ferrous materials while providing heat resistance for harder workpiece applications. The H35ALV-C-3 series designation places this tool in a medium-helix, roughing-geometry family. It is rated for use with high-precision toolholders to maintain TIR within specification. Typical applications include pocket milling, contouring, and adaptive roughing strategies on multi-axis CNC machining centers.

Key Features

• Solid carbide construction for rigidity and wear resistance in high-speed milling
• Zplus PVD coating reduces friction and extends tool life in aluminum and non-ferrous cuts
• Variable index pitch reduces harmonic chatter during aggressive material removal
• 0.0100-inch corner radius with tight tolerance of -0.0020 to 0.0020 inches for consistent edge geometry
• Centercutting design allows direct plunge entry without pre-drilling
• Right-hand flute direction and cutting orientation compatible with standard CNC spindle configurations

Compatibility

Designed for use with high-precision toolholders. Primary workpiece material is aluminum and non-ferrous metal (material code N). Secondary workpiece materials include steel, stainless steel, cast iron, high-temperature alloy, and hard material (material codes P, M, S, H). Part of the H35ALV-C-3 series.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully powered down and the machine in a safe, locked-out state. Seat the straight cylindrical shank fully into a high-precision toolholder and torque the retention mechanism per the toolholder manufacturer specifications. Verify runout against the 0.0003-inch maximum TIR specification using a dial indicator before commencing cuts. Confirm programmed feeds, speeds, and depth of cut are appropriate for the workpiece material before engaging the tool.
