Helical Solutions 45400 Corner Radius End Mill 3/4in 5 Flute

Product Description

The HELICAL SOLUTIONS 45400 is a solid carbide corner radius end mill designed for high-performance material removal in ferrous and non-ferrous machining applications. The tool features a 3/4 inch cutting diameter, a 0.1900 inch corner radius, and five flutes with a variable pitch configuration that reduces harmonic vibration during aggressive cuts. The APLUS PVD coating extends tool life when cutting steel, cast iron, stainless steel, superalloys, and titanium. At 5 inches overall length with a 2.75 inch length of cut, this end mill is built for both roughing and finishing passes in a single setup.

This end mill is suited for CNC machining centers running steel and cast iron as primary workpiece materials, with secondary capability in stainless steel, non-ferrous metals, superalloys, and titanium. The HEV-5 series is engineered for shops that demand tight tolerance work without sacrificing material removal rates. The single-end, center-cutting geometry allows plunge entry as well as conventional peripheral milling. It is intended for use with high-precision toolholders to maintain the 0.0005 inch maximum TIR specification. Applications span job shop work, aerospace component machining, and general metalworking in both prototype and production environments.

Key Features

• 0.1900 inch corner radius with a tight tolerance of -0.0020 to 0.0020 inches for consistent blending on shoulder features
• Five-flute variable pitch design reduces chatter and supports both roughing and finishing in steel and cast iron
• APLUS PVD coating provides enhanced wear resistance across ferrous and difficult-to-machine materials
• Center-cutting geometry enables direct plunge entry without a pre-drilled pilot hole
• Right-hand flute direction and right-hand cutting for standard CNC spindle compatibility
• Straight-cylindrical shank with h6 tolerance fits high-precision collet and hydraulic toolholders

Compatibility

Designed for use with high-precision toolholders. Suitable for machining steel, cast iron, stainless steel, non-ferrous metals, superalloys, and titanium. Part of the HELICAL SOLUTIONS HEV-5 series.

Installation Notes

Installation should be performed by a qualified CNC machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool changer is disabled before loading or removing the end mill. Use a high-precision collet, hydraulic, or shrink-fit toolholder to maintain the specified 0.0005 inch maximum TIR. Verify runout with a dial indicator before beginning production cuts to avoid premature tool wear or part deviation.
