Helical Solutions 59097 Corner Radius End Mill 3/8 in Carbide

Product Description

The HELICAL SOLUTIONS 59097 is a 3-flute, solid carbide corner radius end mill designed for high-efficiency material removal and finishing in aluminum and non-ferrous metal applications. Built to Series H35AL-3 specifications, it features a 35-degree medium helix angle and a Zplus PVD coating applied through a proprietary process. The 0.030-inch corner radius reduces stress concentration at the cutting edge and extends tool life in demanding cuts. At 3/8 inch diameter with a 1-inch length of cut and 3-inch overall length, this end mill suits a wide range of milling operations where precision edge geometry and surface finish are critical.

This end mill is engineered primarily for aluminum and non-ferrous metals, with secondary capability in steel, stainless steel, cast iron, high-temperature alloys, and hard materials. The centercutting design allows plunge entry, making it suitable for slotting, profiling, and pocket milling. A coarse pitch flute geometry promotes chip evacuation during aggressive cuts. It is intended for use with high-precision toolholders to maintain the TIR maximum of 0.0003 inch specified by the manufacturer. Typical applications include CNC milling centers in production machining, tool-and-die, and aerospace-related shops.

Key Features

• Solid carbide construction for rigidity and wear resistance in non-ferrous and multi-material cuts
• Zplus PVD coating (proprietary) optimized for aluminum and non-ferrous metal adhesion resistance
• 0.030-inch corner radius with a tolerance of -0.0020 to +0.0020 inch for consistent edge geometry
• 3-flute, right-hand spiral, centercutting design supports plunge, slot, and profile milling
• 35-degree medium helix angle balances cutting forces and chip flow at higher feed rates
• h6 shank and mill diameter tolerances for reliable runout performance in precision toolholders

Compatibility

Designed for use with high-precision toolholders. Primary workpiece material is aluminum and non-ferrous metal; secondary materials include steel, stainless steel, cast iron, high-temperature alloys, and hard materials. Series H35AL-3.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Ensure the machine spindle and toolholder are fully de-energized and at rest before tool changes. Mount in a high-precision collet or toolholder that meets the 0.0003-inch TIR maximum to protect edge geometry. Verify cutting direction is set to right-hand before beginning any cut cycle.
