Helical Solutions 48461 Corner Radius End Mill 1/2 in 3 Flute

Product Description

The HELICAL SOLUTIONS 48461 is a solid carbide corner radius end mill designed for high-performance material removal in precision machining applications. Built on the H40ALV-3 series platform, it features a 0.5000-inch mill diameter, a 0.0150-inch corner radius, and 3 helical flutes with a variable pitch and variable index geometry. The Zplus PVD coating enhances wear resistance and thermal stability. With a 2.0000-inch length of cut and a 4.0000-inch overall length, this tool is suited for both roughing and finishing operations in a single setup. It is centercutting and runs in a right-hand cutting direction with a straight-cylindrical shank.

This end mill is primarily optimized for aluminum and non-ferrous metals, with secondary capability in steel, stainless steel, cast iron, high-temperature alloys, and hard materials. It is intended for use with high-precision toolholders and is well suited to CNC machining centers in production shops, tool rooms, and job shops requiring tight tolerances and consistent surface finish. The long-reach configuration and variable pitch flutes help reduce chatter during deep-pocket and side-milling passes.

Key Features

• 0.0150-inch corner radius with a tolerance of -0.0020 to 0.0020 inches for consistent edge geometry
• Variable pitch, variable index flute design reduces harmonic vibration and chatter
• Zplus PVD coating for improved wear resistance in aluminum and non-ferrous applications
• Centercutting capability allows plunge entry without pre-drilling
• Long flute configuration: 2.0000-inch length of cut on a 4.0000-inch overall length
• Mill diameter and shank diameter held to h6 tolerance for precision toolholder fit

Compatibility

Designed for use with high-precision toolholders. Primary workpiece material is aluminum and non-ferrous metal; secondary workpiece materials include steel, stainless steel, cast iron, high-temperature alloy, and hard material. Part of the HELICAL SOLUTIONS H40ALV-3 series.

Installation Notes

Installation is performed by a CNC machinist or tooling setup technician using a high-precision collet or shrink-fit toolholder. Verify runout does not exceed the 0.0003-inch TIR maximum before commencing a cut. Ensure the machine spindle and toolholder are clean and free of debris before seating the shank. Follow the toolholder manufacturer torque specifications when tightening retention hardware.
