Helical Solutions 46336 Corner Radius End Mill 1/2 in 3 Flute

Product Description

The HELICAL SOLUTIONS 46336 is a solid carbide corner radius end mill designed for high-performance milling in both roughing and finishing applications. It features a 0.5000-inch cutting diameter, a 0.0150-inch corner radius, and three helical flutes with a variable pitch and variable index geometry. The Zplus PVD coating is applied to extend tool life and reduce built-up edge, particularly in non-ferrous and aluminum workpiece materials. At 4.0000 inches overall length with a 0.6250-inch length of cut, this tool is built for extended-reach setups while maintaining rigidity. It is centercut-capable, allowing plunge entry without a pre-drilled hole.

This end mill is suited for precision machining environments where both aluminum and non-ferrous metals are the primary workpiece material, with secondary capability in steel, stainless steel, cast iron, high-temperature alloys, and hard materials. The extended reach design and 2.2500-inch reach length make it applicable to deep-pocket and cavity milling operations. The straight-cylindrical shank is sized at 0.5000 inches with an h6 tolerance for use in high-precision toolholders. The Series H40ALV-RN-3 designation places this tool in Helical Solutions' variable-index line targeting aluminum and multi-material production environments.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cuts
• Zplus PVD coating optimized for aluminum and non-ferrous milling, reduces friction and edge buildup
• Variable pitch, variable index flute geometry minimizes chatter and harmonic vibration
• Centercut end geometry allows direct plunge entry without a pilot hole
• Extended reach design with 2.2500-inch reach length and 0.4750-inch neck diameter for deep-pocket access
• Right-hand cut, right-hand flute direction with high helix style for efficient chip evacuation

Compatibility

Designed for use with high-precision toolholders. Suitable as a direct replacement or upgrade within the HELICAL SOLUTIONS H40ALV-RN-3 series for applications involving aluminum, non-ferrous metals, steel, stainless steel, cast iron, high-temperature alloys, and hard materials.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Seat the straight-cylindrical shank fully in a high-precision toolholder and verify runout does not exceed the 0.0003-inch maximum TIR specification before cutting. Confirm spindle direction is set to right-hand rotation before engaging the workpiece. Inspect the corner radius and cutting edges for chips or damage before each setup.
