Helical Solutions 29422 Corner Radius End Mill 0.5in 3 Flute

Product Description

The HELICAL SOLUTIONS 29422 is a solid carbide corner radius end mill designed for high-performance material removal in aluminum and non-ferrous metal applications. It features a 0.5-inch mill diameter, a 1.625-inch length of cut, and a 0.03-inch corner radius that reduces stress concentration at the cutting edge and extends tool life. The three-flute, right-hand helical geometry is optimized for chip evacuation and surface finish in softer, gummier materials. A Zplus PVD coating provides additional lubricity and heat resistance. This tool is intended for use in CNC machining centers and is typically handled by machinists and tooling specialists in job shop, aerospace, and general manufacturing environments.

This end mill is suited for roughing and finishing passes on aluminum, brass, copper, and similar non-ferrous metals. Its coarse pitch and high helix style support aggressive material removal rates while keeping chip loads manageable. Secondary workpiece materials include steel, stainless steel, cast iron, high temperature alloys, and hard materials, making this a versatile option across a range of production setups. It is part of the H45AL-C-3 series and is designed for use with high-precision toolholders to maintain runout within the specified TIR maximum.

Key Features

• Solid carbide construction for rigidity and wear resistance in non-ferrous and ferrous applications
• Zplus PVD coating enhances lubricity and thermal stability at the cutting edge
• 0.03-inch corner radius reduces edge chipping and improves part surface finish
• Three-flute, right-hand helical geometry promotes efficient chip evacuation
• Centercutting design allows plunge entry into workpieces
• Straight-cylindrical shank with h6 tolerance for consistent clamping in precision toolholders
• TIR maximum of 0.0003 inches supports tight-tolerance machining operations

Compatibility

Designed for use with high-precision toolholders. Primary workpiece material is aluminum and non-ferrous metal (Material Code N). Secondary materials include steel, stainless steel, cast iron, high temperature alloys, and hard materials (Material Codes P, M, S, H). Part of the HELICAL SOLUTIONS H45AL-C-3 series.

Installation Notes

Installation and tool changes should be performed by qualified machinists with the spindle fully powered down and the machine in a safe, locked-out state. Use a high-precision collet or hydraulic toolholder to stay within the specified TIR maximum of 0.0003 inches. Verify runout with a dial indicator before beginning a production run. Follow the tooling manufacturer and machine builder recommendations for feed rate, spindle speed, and depth of cut based on workpiece material and setup rigidity.
