Helical Solutions 45287 Corner Radius End Mill 1/2 in 5 Flute

Product Description

The HELICAL SOLUTIONS 45287 is a solid carbide corner radius end mill designed for high-performance material removal in demanding machining applications. Built on the HEV-5 platform, it features a 0.5000 inch mill diameter, a 0.0600 inch corner radius, and 5 flutes with a variable pitch configuration. The APLUS PVD coating provides thermal and wear resistance suited for extended tool life in ferrous and hard materials. At 3 inches overall length with a 1.25 inch length of cut, this single-end, center-cutting tool handles both roughing and finishing passes. It mounts on a 0.5000 inch straight-cylindrical shank and is compatible with high-precision toolholders.

This end mill is engineered for machinists working in steel, cast iron, stainless steel, non-ferrous metals, superalloys, and titanium. The right-hand flute direction and right-hand cutting direction make it a standard fit for conventional CNC milling setups. The variable pitch geometry helps suppress chatter during aggressive cuts, making it well-suited for both roughing and finish milling operations in job shops, aerospace, and general metalworking environments.

Key Features

• 0.0600 inch corner radius reduces stress concentration and extends edge life at workpiece corners
• 5-flute, variable pitch design suppresses chatter and improves surface finish
• APLUS PVD coating provides enhanced wear and heat resistance for steel and cast iron applications
• Center-cutting geometry allows plunge entry without a pre-drilled pilot hole
• Solid carbide construction delivers rigidity and dimensional stability at elevated cutting speeds
• Compatible with high-precision toolholders for tight runout control — TIR maximum 0.0005 inch

Compatibility

Designed for use with high-precision toolholders. Primary workpiece materials are steel and cast iron; secondary workpiece materials include stainless steel, non-ferrous metals, superalloys, and titanium. Part of the Helical Solutions HEV-5 series.

Installation Notes

Installation is performed by machinists or CNC setup technicians following standard toolholder torque and runout verification procedures. Ensure the machine spindle is fully stopped and locked before loading or removing the end mill. Seat the shank fully in the toolholder collet or shrink-fit chuck and verify runout with a dial indicator before starting a cut. Consult the toolholder manufacturer and applicable shop safety protocols for secure clamping requirements.
