Helical Solutions 48471 Corner Radius End Mill 1/2 in 3 Flute

Product Description

The HELICAL SOLUTIONS 48471 is a solid carbide corner radius end mill designed for high-performance milling in both roughing and finishing operations. It features a 1/2 inch cutting diameter, a 2 inch length of cut, and a 0.0600 inch corner radius that reduces stress concentration at the cutting edge and extends tool life. The three-flute, right-hand spiral geometry paired with a variable pitch design helps break up harmonics and suppress chatter during aggressive cuts. A Zplus PVD coating optimizes the tool for aluminum and non-ferrous metals while maintaining capability across steel, stainless steel, cast iron, high-temperature alloys, and hard materials. This tool is installed and operated by machinists and CNC tooling professionals in production and job-shop environments.

This end mill is suited for use on CNC machining centers requiring a long-reach tool in the H40ALV-3 series. Its primary application is aluminum and non-ferrous metal milling, with secondary capability in steel, stainless steel, cast iron, high-temperature alloys, and hard materials. The centercutting design allows plunge entry, and the single-end configuration is standard for toolholder mounting. It is specified for use with high-precision toolholders to maintain the 0.0003 inch maximum TIR requirement.

Key Features

• Solid carbide construction for rigidity and wear resistance across demanding workpiece materials
• Zplus PVD coating optimized for aluminum and non-ferrous metals, with cross-material capability
• 0.0600 inch corner radius with a tight tolerance of -0.0020 to 0.0020 inches
• Variable pitch, high-helix geometry reduces chatter in roughing and finishing passes
• Centercutting design enables direct plunge entry without a pre-drilled hole
• Straight-cylindrical shank with h6 tolerance for secure, repeatable toolholder seating

Compatibility

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

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. The tool must be mounted in a high-precision toolholder to maintain the specified maximum TIR of 0.0003 inches. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify runout with a dial indicator after seating to confirm proper setup before cutting.
