Helical Solutions 59925 Corner Radius End Mill 3/8 in 6 Flute

Product Description

The HELICAL SOLUTIONS 59925 is a solid carbide corner radius end mill designed for high-performance material removal in demanding machining applications. The 59925 features a 3/8 inch diameter, a 0.0600 inch corner radius, and a 6-flute variable-index geometry that supports both roughing and finishing passes in a single tool. The Tplus PVD coating improves heat resistance and edge life when cutting abrasive and hard materials. This end mill is center-cutting and runs in a right-hand cutting direction with a right-hand flute spiral. It is intended for use in precision CNC machining centers with high-quality toolholders.

This end mill is built for machinists working with stainless steel, high-temperature alloys, and hardened steels. The HEV-6 series variable-index design reduces harmonic chatter during aggressive cuts, making it suitable for both roughing passes and finish work on difficult-to-machine materials. Secondary applications include non-ferrous metals and other hard materials. The single-end, straight-cylindrical shank fits standard 3/8 inch precision toolholders. Typical users include CNC machinists in job shops, aerospace, and medical manufacturing environments.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• Tplus PVD coating enhances thermal stability and extends tool life in stainless steel and high-temperature alloys
• 6-flute variable-index design reduces chatter and supports both roughing and finishing in one tool
• 0.0600 inch corner radius protects cutting edges and improves surface finish at part corners
• Center-cutting capability allows plunge entry and versatile toolpath strategies
• Straight-cylindrical shank compatible with high precision toolholders for minimal runout

Compatibility

Designed for use with high precision toolholders. Rated for primary workpiece materials including stainless steel, high-temperature alloys, and hardened steel; secondary materials include non-ferrous metals and hard materials.

Installation Notes

Installation and setup should be performed by a qualified CNC machinist. Seat the shank fully in a high-precision toolholder and verify runout does not exceed the specified TIR maximum before cutting. Ensure the spindle and machine tool are fully stopped before loading or unloading the tool. Follow machine tool manufacturer guidelines for speeds, feeds, and depth of cut appropriate to the workpiece material.
