Helical Solutions 82996 Corner Radius End Mill 3/8 in 5 Flute

Product Description

The HELICAL SOLUTIONS 82996 is a 5-flute, solid carbide corner radius end mill engineered for demanding material removal in stainless steel, superalloys, and titanium. It carries a 3/8-inch mill diameter, a 1-inch length of cut, and a 0.09-inch corner radius. The Tplus PVD coating provides elevated heat and wear resistance suited to high-temperature alloy machining. The variable-pitch flute geometry reduces harmonic vibration during aggressive cuts. This tool handles both roughing and finishing operations in a single setup, making it a practical choice for shops running tight-tolerance work in difficult materials.

The 82996 belongs to the Helical HEV-5 series, designed specifically for stainless steel, superalloys, and titanium applications. It is a single-end, centercutting tool with right-hand flute direction and right-hand cutting direction. The straight-cylindrical shank measures 3/8 inch in diameter, and the 3-inch overall length fits standard milling chucks and high-precision toolholders. It is suited to CNC machining centers running stainless, Inconel, titanium, and similar hard or work-hardening materials. Secondary applications include non-ferrous metals and hard materials.

Key Features

• 5-flute variable-pitch design reduces chatter and harmonic vibration during high-load cuts
• Tplus PVD coating improves tool life and performance in stainless steel, superalloys, and titanium
• Centercutting geometry allows plunge entry without a pre-drilled hole
• 0.09-inch corner radius extends edge life and reduces stress concentration at the tool tip
• Solid carbide construction provides rigidity and wear resistance superior to HSS alternatives
• Handles both roughing and finishing operations, reducing tool changes per setup

Compatibility

Designed for use with high-precision toolholders. Primary workpiece materials are stainless steel, superalloys, and titanium (Material Code M and S). Secondary workpiece materials include non-ferrous metals and hard materials (Material Code N and H). Part of the Helical HEV-5 series.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC tooling technician. Seat the straight-cylindrical shank fully in a high-precision toolholder and verify runout does not exceed the 0.0005-inch TIR maximum before cutting. Ensure the spindle and any workpiece clamping are secured before engaging the tool. Consult machine and toolholder manufacturer specifications for appropriate torque values and clamping procedures.
