Helical Solutions 48531 Corner Radius End Mill 5/8 in 3 Flute

Product Description

The HELICAL SOLUTIONS 48531 is a single-end, corner radius end mill designed for high-performance milling in both roughing and finishing operations. Built from solid carbide and coated with a proprietary Zplus PVD coating, it measures 5/8 inch in diameter with a 1.25-inch length of cut and a 3.5-inch overall length. The 0.1250-inch corner radius reduces stress concentration at the cutting edge, extending tool life and improving surface finish. The 3-flute geometry paired with a variable pitch and high helix angle supports efficient chip evacuation and reduced chatter, making it well suited for demanding material removal applications.

This end mill is optimized for use in aluminum and non-ferrous metals as its primary application, with secondary capability in steel, stainless steel, cast iron, high temperature alloys, and hard materials. It is rated for use in high-precision toolholders and is appropriate for CNC machining centers in both job shop and production environments. The centercutting design allows for plunge entry. Machinists and CNC programmers working in aerospace, mold, and general metalworking applications will find this tool applicable across a wide range of setups.

Key Features

• Solid carbide construction for rigidity and heat resistance across a broad range of workpiece materials
• Zplus PVD coating optimized for aluminum and non-ferrous metal machining
• 0.1250-inch corner radius with a tight tolerance of -0.0020 to +0.0020 inch
• Variable pitch geometry reduces harmonic vibration and chatter during cutting
• Centercutting design enables direct plunge milling without a pre-drilled entry point
• Right-hand cut and right-hand spiral flute direction for standard CNC spindle compatibility
• Maximum TIR of 0.0003 inch ensures consistent accuracy in high-precision toolholder setups

Compatibility

Designed for use with high-precision toolholders. Part of the HELICAL SOLUTIONS H40ALV-3 series. Primary workpiece material is aluminum and non-ferrous metals; secondary materials include steel, stainless steel, cast iron, high temperature alloys, and hard materials.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician. Secure the 5/8-inch straight-cylindrical shank in a high-precision toolholder to the manufacturer-specified clamping torque for that holder. Verify runout does not exceed the rated TIR maximum before beginning a cut. Follow all machine guarding and lockout/tagout procedures before changing tooling.
