Helical Solutions 48746 Corner Radius End Mill 1 in 3 Flute

Product Description

The HELICAL SOLUTIONS 48746 is a solid carbide corner radius end mill designed for high-performance material removal in both roughing and finishing operations. It features a 1 inch diameter, a 2 inch length of cut, and a 0.125 inch corner radius, making it well suited for producing blended edge profiles while maintaining tool life. The Zplus PVD coating is optimized primarily for aluminum and non-ferrous metals, though the tool is rated for use in steel, stainless steel, cast iron, high temperature alloys, and hard materials. The 40-degree high helix promotes efficient chip evacuation, and the variable pitch geometry helps reduce harmonic vibration during aggressive cuts. This tool is installed and operated by machinist professionals in CNC milling environments.

The 48746 is built around the H40ALV-3 series platform, which targets aluminum and non-ferrous machining as its primary application while extending capability into ferrous and exotic alloys as secondary workpiece materials. With a 5 inch overall length and a straight cylindrical shank, it fits standard high-precision toolholders used on vertical and horizontal CNC machining centers. The center-cutting geometry allows plunge entry, and the right-hand flute spiral with right-hand cutting direction suits conventional CNC toolpath strategies. It is appropriate for both production shop and job shop environments requiring a single-end tool with consistent corner geometry.

Key Features

• Solid carbide construction for rigidity and wear resistance across ferrous and non-ferrous workpiece materials
• Zplus PVD coating optimized for aluminum and non-ferrous metals with extended secondary material capability
• 0.125 inch corner radius with a tight tolerance of -0.0020 to 0.0020 inches for consistent blended-edge results
• Variable pitch, high helix (40 degrees) design reduces chatter and improves chip flow in demanding cuts
• Center-cutting end geometry enables direct plunge entry without a pre-drilled pilot hole
• Maximum TIR of 0.0003 inches supports use in high-precision toolholders for tight-tolerance work

Compatibility

Designed for use with high-precision toolholders on CNC milling machines. Primary workpiece material is aluminum and non-ferrous metal; secondary workpiece materials include steel, stainless steel, cast iron, high temperature alloys, and hard materials. Part of the Helical Solutions H40ALV-3 series.

Installation Notes

Installation should be performed by a qualified machinist following standard CNC toolchange procedures. Ensure the machine spindle is fully stopped and the tool is secured in a high-precision toolholder to the toolholder manufacturer's specified torque and runout requirements. Verify tool projection and confirm TIR at setup before initiating a cut. Always follow the tool manufacturer's recommended speeds and feeds for the specific workpiece material and coating being used.
