Helical Solutions 59119 Corner Radius End Mill 1/2 in 3 Flute

Product Description

The HELICAL SOLUTIONS 59119 is a solid carbide corner radius end mill designed for precision milling of aluminum and non-ferrous metals, with secondary capability in steel, stainless steel, cast iron, high-temperature alloys, and hard materials. It features a 1/2 inch diameter, a 0.0600 inch corner radius, and three right-hand spiral flutes with a 35-degree medium helix angle. The Zplus PVD coating improves wear resistance and chip evacuation in aluminum applications. At 2.5 inches overall length with a 0.625 inch length of cut, this stub-length tool offers rigidity suited for high-precision toolholders. Machinists and tool-and-die professionals use this end mill for both roughing and finishing passes in production and job-shop environments.

This end mill is built primarily for aluminum and non-ferrous metal milling, with workpiece material code N as the primary application and codes P, M, S, and H covering steel, stainless steel, cast iron, high-temperature alloys, and hard materials as secondary applications. The stub-length geometry and coarse pitch make it well suited for aggressive material removal in CNC machining centers where tool deflection must be minimized. The single-end, centercutting design allows plunge entry and full-slot milling. It is intended for use with high-precision toolholders to maintain runout within the 0.0003 inch maximum TIR specification.

Key Features

• Solid carbide construction for rigidity and thermal stability in high-speed cutting
• Zplus PVD coating engineered for aluminum and non-ferrous metal applications
• 0.0600 inch corner radius with a tight tolerance of -0.0020 to +0.0020 inches
• 35-degree medium helix angle promotes smooth chip evacuation and reduced cutting forces
• Centercutting single-end design allows plunge milling and full-slot operations
• Mill and shank diameter both held to h6 tolerance for consistent toolholder fit
• Maximum TIR of 0.0003 inches supports high-precision finish work

Compatibility

Designed for use with high-precision toolholders in CNC machining applications. Part of the HELICAL SOLUTIONS H35AL-3 series, optimized for aluminum and non-ferrous metal milling with secondary compatibility in steel, stainless steel, cast iron, high-temperature alloys, and hard materials.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer's clamping specifications. Ensure the shank is fully seated and clean before tightening to avoid runout beyond the 0.0003 inch TIR limit. Verify spindle speed, feed rate, and depth-of-cut parameters in the CAM program before running the first pass. Do not exceed the tool's listed length of cut when programming axial engagement.
