Helical Solutions 82998 Corner Radius End Mill 1/2 in 5 Fl

Product Description

The HELICAL SOLUTIONS 82998 is a 5-flute, solid carbide corner radius end mill engineered for demanding material removal in stainless steel, superalloys, and titanium. It carries a 0.5000-inch mill diameter, a 1-inch length of cut, and a 0.0100-inch corner radius that reduces edge chipping at the cutting perimeter. The Tplus PVD coating provides heat and wear resistance suited to high-temp alloy applications. Variable pitch flute spacing minimizes harmonic vibration during aggressive cuts, supporting both roughing and finishing operations in a single tool. This end mill is single-end, centercutting, and runs right-hand flute direction and cutting direction.

Designed for use in CNC machining centers where tight tolerances and surface finish quality are critical, the 82998 targets applications in aerospace, medical, and industrial manufacturing environments where stainless steel, titanium, and nickel-based superalloys are common workpiece materials. The HEV-5 series variable-pitch geometry is specifically suited to high-speed machining strategies in these difficult-to-cut materials. Secondary material applications include non-ferrous metals and hard materials, extending the tool's utility across mixed-material shops. A high-precision toolholder is recommended to take full advantage of the 0.0005-inch maximum TIR specification.

Key Features

• 5-flute variable-pitch design reduces vibration and chatter in hard and high-temp alloys
• Tplus PVD coating delivers enhanced wear resistance for stainless steel, superalloys, and titanium
• 0.0100-inch corner radius with a tight tolerance of -0.0020 to 0.0020 inches protects the cutting edge
• Centercutting geometry allows plunge entry and full-slot milling capability
• Straight-cylindrical shank at 0.5000-inch diameter with h6 tolerance for secure, repeatable toolholder fit
• Handles both roughing and finishing material removal strategies in a single tool

Compatibility

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

Installation Notes

Installation is performed by a qualified CNC machinist or tooling technician. The tool must be seated fully in a high-precision toolholder and torqued per the toolholder manufacturer's specification before spindle operation. Verify runout does not exceed 0.0005 inches TIR before beginning a production cut. Confirm machine spindle is fully stopped and in a safe state before loading or unloading the end mill.
