Helical Solutions 46631 Corner Radius End Mill 3/4 in

Product Description

The HELICAL SOLUTIONS 46631 is a solid carbide corner radius end mill designed for high-performance milling in both roughing and finishing operations. It features a 3/4 inch diameter, a 1 inch length of cut, and a 0.0300 inch corner radius that protects the cutting edge and extends tool life on demanding materials. The 3-flute geometry with a variable pitch and 40-degree high helix angle promotes efficient chip evacuation and reduces chatter. A Zplus PVD coating enhances wear resistance and surface finish quality. This tool is intended for use by machinists and CNC operators working in production and job shop environments.

The 46631 is optimized for aluminum and non-ferrous metals as its primary workpiece materials, with secondary capability in steel, stainless steel, cast iron, high temperature alloys, and hard materials. Its extended reach design - with a 5 inch reach length and 7 inch overall length - makes it well suited for deep-pocket milling, tall-wall profiling, and applications where standard-length tools cannot access the workpiece. It is specified for use with high precision toolholders to maintain runout control.

Key Features

• Solid carbide construction for rigidity and dimensional stability under cutting loads
• Zplus PVD coating provides wear resistance across ferrous and non-ferrous materials
• Variable pitch flute spacing reduces harmonic vibration and chatter during aggressive cuts
• 0.0300 inch corner radius protects cutting edges and improves corner integrity on finished surfaces
• Extended reach with 5 inch reach length and 7 inch overall length enables deep-pocket and tall-wall applications
• Center cutting capability allows plunge entry into workpiece material

Compatibility

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

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC operator. Seat the shank fully and concentrically in a high precision toolholder to maintain TIR within specification; this tool has a maximum TIR of 0.0003 inches. Verify spindle direction is set to right-hand rotation before running. Inspect the corner radius and cutting edges for damage before each use, and never exceed the rated reach depth without confirming workpiece fixturing is secure.
