Helical Solutions 43497 Corner Radius End Mill 1/2in 4 Flute

Product Description

The HELICAL SOLUTIONS 43497 is a solid carbide corner radius end mill designed for high-performance milling in steel and cast iron applications. With a 0.5000 inch mill diameter, 0.0600 inch corner radius, and 4 variable-index flutes, it delivers consistent edge geometry suited for both roughing and finishing passes. The APLUS PVD coating reduces friction and extends tool life in demanding ferrous materials. The stub-length flute configuration and 0.6250 inch length of cut provide rigidity in tight setups, making this tool a reliable choice for machinists and tool-and-die professionals working to tight tolerances.

This end mill is intended for use in CNC milling operations on low-alloy steel, medium alloy steel, tool steel, and cast iron. The HSV-4 series is engineered for use with high-precision toolholders. Right-hand cutting and right-hand flute direction make it compatible with standard spindle configurations. Its single-end, straight-cylindrical shank seats cleanly in collet and end mill holders. It is well suited for production environments and job shop applications where consistent corner geometry and surface finish are critical.

Key Features

• 0.0600 inch corner radius with a tolerance of -0.0020 to 0.0020 inches for repeatable edge geometry
• Variable-index flute spacing reduces harmonic chatter during aggressive cuts
• APLUS PVD proprietary coating optimized for steel and cast iron machinability
• Solid carbide construction provides stiffness and wear resistance at elevated cutting speeds
• Stub-length flute (0.6250 inches LOC) maximizes rigidity in short-reach setups
• Maximum TIR of 0.0005 inches supports use in high-precision toolholders

Compatibility

Designed for use with high-precision toolholders. Recommended for milling low-alloy steel, medium alloy steel, tool steel, and cast iron workpieces. Part of the HELICAL SOLUTIONS HSV-4 series.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Seat the straight-cylindrical shank fully into a clean, undamaged collet or end mill holder before torquing the retention mechanism. Verify runout at the cutting edge prior to first use. Follow the toolholder manufacturer specifications and your facility safety procedures when loading or unloading tooling from a live spindle.
