Helical Solutions 82762 Corner Radius End Mill 1/8 in 3 Flute

Product Description

The HELICAL SOLUTIONS 82762 is a solid carbide corner radius end mill engineered for high-performance material removal in aluminum and non-ferrous metal applications. With a 1/8 inch mill diameter, 0.0150 inch corner radius, and three right-hand spiral flutes, this tool balances chip evacuation with surface finish quality across both roughing and finishing operations. The Zplus PVD coating reduces built-up edge and extends tool life when cutting aluminum and similar materials. At 2.5 inches overall length with a 1/2 inch length of cut, the 82762 is a compact, single-end centercutting tool suited for CNC machining centers and high-precision toolholders. Licensed machinists and CNC programmers running production or prototype work in aluminum will recognize this as a purpose-built geometry for that material class.

The 82762 belongs to the H35AL-3 series, which targets aluminum and non-ferrous metals as primary workpiece materials. Secondary material compatibility includes steel, stainless steel, cast iron, high-temperature alloys, and hard materials, though primary performance optimization is for non-ferrous work. The coarse pitch and 35-degree medium helix angle promote aggressive chip flow out of the cut zone, making this tool well-suited for slotting, profiling, and finishing passes on aluminum components in both job shop and production environments. It is specified for use with high-precision toolholders to maintain runout within its rated TIR maximum.

Key Features

• Solid carbide construction provides rigidity and wear resistance for consistent dimensional accuracy
• Zplus PVD coating optimized for aluminum and non-ferrous metals, reducing built-up edge
• 0.0150 inch corner radius with a tolerance of -0.0020 to 0.0020 inches for controlled edge blending
• 3-flute, right-hand cut, right-hand spiral geometry supports both roughing and finishing in a single tool
• Centercutting design allows plunge entry into the workpiece
• Maximum TIR of 0.0003 inches supports tight tolerance work when paired with high-precision toolholders

Compatibility

The 82762 is designed for use with high-precision toolholders and is rated for aluminum and non-ferrous metal as primary workpiece materials. Secondary workpiece material codes indicate suitability across steel, stainless steel, cast iron, high-temperature alloys, and hard materials. Straight-cylindrical shank at 1/8 inch diameter fits standard collet chucks and end mill holders sized for that shank diameter.

Installation Notes

Installation is performed by a CNC machinist or toolroom technician. Before mounting, verify the toolholder bore and collet are clean and free of chips or runout-inducing debris. Torque collet nuts according to the toolholder manufacturer specifications. Confirm tool projection and gauge length in the CAM program before cutting to avoid interference and to maintain the rated TIR maximum of 0.0003 inches.
