Helical Solutions 81753 Corner Radius End Mill 1/2 in 5 Flute

Product Description

The HELICAL SOLUTIONS 81753 is a solid carbide corner radius end mill designed for high-performance milling in ferrous and non-ferrous materials. It features a 1/2 inch diameter, a 0.6250 inch length of cut, and a 0.0100 inch corner radius, making it well suited for both roughing and finishing operations where edge strength and surface finish matter. The APLUS PVD coating reduces heat buildup and extends tool life in demanding applications. With five flutes and a variable index pitch, it generates less harmonic vibration compared to fixed-pitch tooling, supporting stable cuts at aggressive feed rates. Licensed machinists and CNC programmers working in job shops, aerospace, and general machining will find this tool sized and coated for production-level use.

This end mill is built for milling steel and cast iron as primary workpiece materials, with secondary capability in stainless steel, non-ferrous metals, superalloys, titanium, and hard materials. The stub length configuration and straight-cylindrical shank keep deflection low, making it practical for pocketing, slotting, and contouring on vertical and horizontal machining centers. It is a single-end, centercutting tool, so it can plunge directly into material. The HEV-5 series is engineered for use with high-precision toolholders to maximize TIR performance.

Key Features

• 0.0100 inch corner radius with a tolerance of -0.0020 to 0.0020 inches for consistent edge geometry
• APLUS PVD coating rated for steel, cast iron, stainless, superalloys, and hard materials
• Five flutes with variable index pitch to reduce chatter and improve surface finish
• Centercutting design allows direct plunge entry without a pre-drilled pilot hole
• Right-hand cut and right-hand spiral flute direction for standard CNC spindle operation
• Maximum TIR of 0.0005 inches when used with high-precision toolholders

Compatibility

The 81753 is part of the HELICAL SOLUTIONS HEV-5 series and is designed for use with high-precision toolholders. Primary workpiece material compatibility includes steel and cast iron. Secondary compatibility covers stainless steel, non-ferrous metals, superalloys, titanium, and hard materials.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician. Seat the straight-cylindrical shank fully in a high-precision collet or toolholder and verify runout before cutting to protect the corner radius and tool life. Confirm spindle direction is set to right-hand rotation before starting the program. Follow the tooling manufacturer feed-and-speed recommendations for the specific workpiece material to avoid premature edge wear.
