Helical Solutions 31587 Corner Radius End Mill 5/8 in 4 Flute

Product Description

The HELICAL SOLUTIONS 31587 is a solid carbide corner radius end mill engineered for high-performance milling in steel and cast iron applications. It features a 5/8 inch diameter, a 0.0300 inch corner radius, and a 1-5/8 inch length of cut, making it well-suited for both roughing and finishing passes in a single setup. The APLUS PVD coating reduces heat buildup and extends tool life in abrasive ferrous materials. A variable pitch design minimizes chatter and vibration, supporting consistent surface finishes at higher feed rates. This tool is installed and operated by CNC machinists and toolroom professionals working in precision manufacturing environments.

This end mill is designed for milling low-alloy steel, medium alloy steel, tool steel, and cast iron. The HSV-4 series is built for use with high precision toolholders where runout control is critical. It is a single-end, right-hand cutting, right-hand flute tool with a straight cylindrical shank, making it compatible with standard ER collet chucks and hydraulic or shrink-fit toolholders in typical CNC machining center setups. The corner radius geometry protects the cutting edge at the tool tip and reduces stress concentration in the workpiece corner.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous materials
• APLUS PVD coating rated for steel and cast iron — reduces friction and extends tool life
• Variable pitch flute spacing suppresses chatter during aggressive cuts
• 0.0300 inch corner radius with a tight tolerance of -0.0020 to +0.0020 inches
• Suitable for both roughing and finishing material removal in a single tool
• Designed for use with high precision toolholders — maximum TIR of 0.0005 inches

Compatibility

Intended for use with high precision toolholders in CNC machining centers. Primary workpiece materials are low-alloy steel, medium alloy steel, tool steel, and cast iron. Part of the HELICAL SOLUTIONS HSV-4 series.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool changer is disabled before changing tooling. Seat the shank fully into the toolholder and torque the retention mechanism to the toolholder manufacturer's specification. Verify runout at the cutting diameter before beginning production cuts, as this tool is rated for a maximum TIR of 0.0005 inches.
