Helical Solutions 82408 Corner Radius End Mill 1/8 in 3 Flute

Product Description

The HELICAL SOLUTIONS 82408 is a solid carbide corner radius end mill designed for high-performance material removal in both roughing and finishing operations. It features a 1/8 inch diameter, a 0.0150 inch corner radius, and three flutes arranged in a variable-pitch, high-helix configuration at 40 degrees. The Zplus PVD coating improves wear resistance and heat dissipation. With a 5/8 inch length of cut and 2.5 inch overall length, this single-end, center-cutting tool is suited for precise contouring, slotting, and profiling in CNC machining centers. It is installed by machinists and CNC operators working in precision manufacturing environments.

This end mill is primarily designed for aluminum and non-ferrous metals, with secondary capability in steel, stainless steel, cast iron, high temperature alloys, and hard materials. The H40ALV-3 series geometry is optimized for high-speed machining strategies where surface finish and corner integrity are critical. The straight cylindrical shank fits standard high-precision toolholders. It is well suited for shops running tight-tolerance parts where corner radius consistency and runout control are priorities.

Key Features

• Solid carbide construction for rigidity and long tool life
• Zplus PVD coating for enhanced wear resistance in aluminum and non-ferrous applications
• Variable-pitch, 40-degree high-helix flutes reduce chatter and improve chip evacuation
• 0.0150 inch corner radius with tolerance of -0.0020 to 0.0020 inches for consistent edge geometry
• Center-cutting design allows for plunge entry
• Maximum TIR of 0.0003 inches for high-precision fitment in toolholders

Compatibility

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

Installation Notes

Installation is performed by a machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool changer or spindle is locked out before loading the tool. Use a high-precision collet or toolholder to maintain runout within the specified TIR maximum. Verify tool projection and stick-out match the programmed cutting parameters before initiating a cut.
