Helical Solutions 86315 Lens Form End Mill 3 Flute Carbide

Product Description

The HELICAL SOLUTIONS 86315 is a solid carbide lens form barrel cutter end mill designed for multi-axis finishing operations, particularly on aluminum workpieces. With a 3-flute geometry and a lens form end profile, this tool produces smooth surface finishes in complex contoured and 3D-machined surfaces. The Nplus finish coating reduces friction and built-up edge, which is critical when cutting aluminum at high feed rates. The 0.5000 inch shank diameter and 0.5000 inch length of cut make this tool well-suited for finish passes where tool deflection control and consistent chip evacuation are priorities. It is installed and used by CNC machinists and manufacturing professionals running 3-axis and multi-axis milling programs.

This end mill is engineered for aluminum finishing applications in multi-axis CNC milling environments. The lens form barrel geometry allows the tool to engage workpiece surfaces at a tangential angle, enabling larger stepovers compared to ball end mills while maintaining fine surface finish quality. It is commonly used in aerospace, mold and die, and precision manufacturing applications where complex surface geometry requires smooth final passes with minimal scallop height. The 3.0000 inch overall length provides adequate reach for most contoured finishing scenarios without excessive overhang.

Key Features

• Lens form barrel end type for tangential surface engagement and reduced scallop height on contoured surfaces
• Solid carbide construction for rigidity and wear resistance in aluminum cutting applications
• Nplus finish coating reduces friction, minimizes built-up edge, and improves chip flow in aluminum
• 3-flute design balances chip evacuation and surface finish quality at high feed rates
• 0.5000 inch shank diameter for secure toolholder engagement in standard ER and end mill holders
• 3.0000 inch overall length provides reach for multi-axis finishing operations

Compatibility

Part of the Helical Solutions End Mills for Aluminum Multi-Axis Finishers 3 Flute Lens Form series. Designed for use in CNC milling machines with standard 0.5000 inch bore toolholders compatible with solid carbide end mills.

Installation Notes

Installation should be performed by a qualified CNC machinist or tooling technician. Secure the shank in a clean, properly sized collet or end mill holder, ensuring adequate engagement depth per the toolholder manufacturer guidelines. Inspect the cutting edges and coating for chips or damage before mounting. Follow the machine tool builder and tooling manufacturer recommendations for speeds, feeds, and depth of cut when programming multi-axis finishing paths.
