Helical Solutions 59130 Corner Radius End Mill 1/2 in 3 Flute

Product Description

The HELICAL SOLUTIONS 59130 is a solid carbide corner radius end mill designed for high-performance material removal in aluminum and non-ferrous metals. It features a 1/2 inch mill diameter, a 1 inch length of cut, and a 0.03 inch corner radius that reduces stress concentration at the cutting edge and extends tool life. With three right-hand helical flutes at a 35-degree helix angle, it handles both roughing and finishing passes in a single tool. The centercutting design allows plunge entry, and the straight cylindrical shank at 1/2 inch diameter seats securely in high-precision toolholders. This tool is part of the H35AL-3 series, optimized for aluminum machining.

The 59130 is built for CNC machining centers and manual mills where aluminum, brass, copper, and similar non-ferrous workpieces require clean, accurate cuts. It is also rated for secondary use in steel, stainless steel, cast iron, high-temperature alloys, and hard materials, making it a versatile option in job shop environments. The uncoated finish is appropriate for aluminum applications where coating buildup can be a concern. Machinists and toolroom technicians working in production and prototype environments will find this end mill suitable for both slotting and profiling operations.

Key Features

• Solid carbide construction provides rigidity and wear resistance across a range of workpiece materials
• 0.03 inch corner radius reduces edge chipping and improves surface finish at corners
• Three-flute, 35-degree right-hand helix geometry optimized for aluminum chip evacuation
• Centercutting design supports plunge milling without a pre-drilled entry hole
• Uncoated finish suited for aluminum and non-ferrous applications where coating adhesion is undesirable
• H35AL-3 series with coarse pitch and medium helix style for balanced roughing and finishing capability

Compatibility

Designed for use with high-precision toolholders. Primary workpiece material is aluminum and non-ferrous metals; rated for secondary use in steel, stainless steel, cast iron, high-temperature alloys, and hard materials. Part of the H35AL-3 end mill series.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a locked-out state. Seat the straight cylindrical shank fully into a high-precision toolholder and torque the retention mechanism per the toolholder manufacturer specification. Verify runout does not exceed the 0.0003 inch maximum TIR before beginning a cut. Inspect the corner radius and cutting edges for chips or wear before each use.
