Helical Solutions 81867 Corner Radius End Mill 1/2 in 5 Flute

Product Description

The HELICAL SOLUTIONS 81867 is a 5-flute, 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 1/2 inch mill diameter, a 2 inch length of cut, and a 0.0300 inch corner radius that extends tool life and reduces chipping at the cutting edge. The Tplus PVD coating enhances wear resistance and heat dissipation, making this end mill well suited for aggressive feeds and speeds. Machinists and tooling professionals working in production or job-shop environments will find this tool delivers consistent results in both roughing and finishing operations.

This end mill is engineered for use on stainless steel, superalloys, and titanium as its primary workpiece materials, with secondary application in non-ferrous metals and hard materials. The single-end, centercutting design with right-hand flute direction and right-hand cutting allows plunge entry and full-slot milling. The variable pitch construction helps dampen harmonic vibration during cuts, making it suitable for high-speed machining centers and rigid setups. It is intended for use with high-precision toolholders to maintain runout control and maximize cutting performance.

Key Features

• 5-flute solid carbide construction for strength and rigidity in tough materials
• 0.0300 inch corner radius reduces stress concentration and extends edge life
• Tplus PVD coating optimized for stainless steel, superalloys, and titanium
• Variable pitch design minimizes chatter and harmonic vibration
• Centercutting geometry allows plunge milling and full-slot entry
• Long flute series with 2 inch length of cut for deeper axial engagement

Compatibility

Designed for use with high-precision toolholders. Primary workpiece materials are stainless steel, superalloys, and titanium (material codes M and S). Secondary workpiece materials include non-ferrous metals and hard materials (material codes N and H).

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Secure the tool in a high-precision toolholder to maintain TIR within specification and prevent premature wear. Ensure the machine spindle and toolholder are clean and undamaged before mounting. Follow the machine tool manufacturer's recommended runout and drawbar torque procedures before beginning any cutting operation.
