Helical Solutions 59163 Corner Radius End Mill 0.5in 3 Flute

Product Description

The HELICAL SOLUTIONS 59163 is a single-end, corner radius end mill designed for high-performance material removal in aluminum and non-ferrous metals. Built from solid carbide and coated with a proprietary Zplus PVD coating, it delivers both roughing and finishing capability in a single tool. The 0.5-inch mill diameter pairs with a 0.09-inch corner radius to blend sharp cutting action with edge protection. Three helical flutes at a 35-degree helix angle evacuate chips efficiently, reducing built-up edge in sticky, low-ferrous materials. The centercutting geometry allows plunge entry, expanding the range of toolpaths available to the operator.

This end mill is engineered for aluminum and non-ferrous metal machining and is suited to CNC milling operations in job shops, aerospace component work, and general precision machining environments. The medium-length flute and straight cylindrical shank make it compatible with high-precision toolholders. Secondary material applications include steel, stainless steel, cast iron, high-temperature alloys, and hard materials, making this a versatile tool when aluminum is the primary workpiece but material mix is part of the workflow.

Key Features

• Solid carbide construction with Zplus PVD coating optimized for aluminum and non-ferrous metals
• 0.09-inch corner radius with a tight tolerance of -0.002 to 0.002 inches for consistent edge geometry
• 35-degree medium helix angle promotes efficient chip evacuation in high-speed aluminum cuts
• Centercutting design allows ramp, plunge, and interpolation entry
• Right-hand flute direction and right-hand cutting with coarse pitch for aggressive material removal
• Maximum TIR of 0.0003 inches ensures runout control in high-precision toolholder setups

Compatibility

Part of the HELICAL SOLUTIONS H35AL-3 series, designed for use with high-precision toolholders. Primary workpiece material is aluminum and non-ferrous metals; secondary compatibility includes steel, stainless steel, cast iron, high-temperature alloys, and hard materials.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle powered down and locked out. Use a high-precision toolholder to stay within the specified TIR maximum of 0.0003 inches. Verify tool runout after seating and before initiating any cut cycle. Follow machine tool manufacturer guidelines for collet torque and retention force - do not substitute standard-tolerance toolholders, as they may exceed the runout specification.
