Helical Solutions 45379 Corner Radius End Mill 3/4in 5 Flute

Product Description

The HELICAL SOLUTIONS 45379 is a solid carbide corner radius end mill designed for high-performance material removal in ferrous and non-ferrous machining applications. It features a 3/4-inch diameter, a 0.1200-inch corner radius, and five flutes with a variable pitch configuration. The APLUS PVD coating improves wear resistance and extends tool life in demanding cuts. This is a single-end, center-cutting tool, making it capable of both plunge entry and lateral milling passes. It is used by CNC machinists and tooling specialists in job shops, production facilities, and aerospace component manufacturing environments.

The 45379 belongs to the HEV-5 series, which is engineered for roughing and finishing operations in a single tool path. With a 1.6250-inch length of cut and a 4-inch overall length, it provides reach appropriate for medium-depth pocketing and profiling. Primary workpiece materials include steel and cast iron. Secondary materials include stainless steel, non-ferrous metals, superalloys, titanium, and hard materials. The straight-cylindrical shank is sized at 3/4 inch and is compatible with high-precision toolholders for reduced runout during high-feed operations.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous and hard material cutting
• APLUS PVD coating reduces friction and extends tool life across steel, cast iron, and stainless applications
• Variable pitch flute geometry helps reduce harmonic chatter during aggressive cuts
• Center-cutting design allows direct plunge entry without a pre-drilled pilot hole
• 0.1200-inch corner radius reduces stress concentrations at part edges and extends tool life on interrupted cuts
• Right-hand cut and right-hand spiral flute direction suits standard CNC spindle rotation

Compatibility

Designed for use with high-precision toolholders. Primary workpiece materials are steel and cast iron. Compatible with secondary workpiece materials including stainless steel, non-ferrous metals, superalloys, titanium, and hard materials. Part of the HELICAL SOLUTIONS HEV-5 series.

Installation Notes

Installation is performed by a CNC machinist or tooling technician. Ensure the toolholder is clean and within specified runout tolerances before seating the shank — maximum TIR for this tool is 0.0005 inches. Confirm spindle direction is set to right-hand rotation before engaging the cut. Follow the machine tool manufacturer and HELICAL SOLUTIONS recommended feeds and speeds for the target workpiece material and coating type.
