Helical Solutions 82810 Corner Radius End Mill 3/16 in 3 Flute

Product Description

The HELICAL SOLUTIONS 82810 is a solid carbide corner radius end mill designed for high-performance material removal in both roughing and finishing operations. With a 0.1875 inch mill diameter, a 0.0150 inch corner radius, and three helical flutes, this tool delivers controlled chip evacuation and reduced edge chipping on complex contours. The Zplus PVD coating extends tool life by improving hardness and thermal resistance at the cutting edge. It is a single-end, centercutting design with a straight cylindrical shank, making it compatible with high-precision toolholders. This tool is installed and operated by machinists and CNC tooling professionals in shop environments requiring tight tolerances and reliable surface finishes.

The 82810 is built primarily for non-ferrous metals including aluminum, with secondary capability across steel, stainless steel, cast iron, high-temperature alloys, and hard materials. Its extended reach configuration, with a 1.0000 inch reach length and a reduced neck diameter of 0.1780 inch, suits applications where access to deep or narrow features is required. The variable pitch and high helix geometry help suppress chatter during aggressive cuts in both conventional and high-speed machining strategies. It fits standard Series H40ALV-RN-3 tooling setups.

Key Features

• Solid carbide construction for rigidity and wear resistance across ferrous and non-ferrous materials
• Zplus PVD coating optimized for aluminum and non-ferrous metal cutting applications
• 0.0150 inch corner radius reduces stress concentration and improves edge durability on contoured features
• Variable pitch flute geometry minimizes harmonic chatter during high-speed passes
• Extended reach design with 1.0000 inch reach length and 0.1780 inch neck diameter for deep-feature access
• Centercutting capability allows plunge entry without a pre-drilled pilot hole

Compatibility

Designed for use with high-precision toolholders as part of the H40ALV-RN-3 series. Suitable for CNC machining centers handling non-ferrous metals as the primary workpiece material, with secondary application across steel, stainless steel, cast iron, high-temperature alloys, and hard materials.

Installation Notes

Installation and tool changes must be performed by qualified machining personnel with the spindle fully stopped and machine power locked out per facility safety procedures. Use a high-precision toolholder to maintain runout within the specified TIR maximum of 0.0003 inch. Inspect the cutting edges and corner radius for chips or wear before each use. Coolant-through is not supported on this tool; apply flood or mist coolant externally as required by the workpiece material and depth of cut.
