Helical Solutions 83105 Corner Radius End Mill 5 Flute

Product Description

The HELICAL SOLUTIONS 83105 is a 5-flute, solid carbide corner radius end mill designed for high-performance milling in demanding materials. It features a 0.5-inch diameter, a 1-inch length of cut, and a 0.0300-inch corner radius that reduces stress concentrations at the cutting edge. The 3-inch overall length pairs with a 0.5-inch straight-cylindrical shank for secure clamping in high-precision toolholders. A Tplus PVD coating delivers enhanced wear resistance and thermal stability. The variable-pitch flute geometry reduces harmonic chatter during aggressive cuts, making this tool well-suited for production environments where surface finish and tool life are both priorities. It is a single-end, centercutting tool with right-hand flute direction and right-hand cutting direction.

This end mill is engineered for milling stainless steel, high-temperature alloys, and hardened steels as primary workpiece materials. Secondary applications include steel and cast iron. It is rated for use in roughing material-removal operations and is compatible with high-precision toolholders. The HEV-C-5 series is built for shops running difficult-to-machine alloys where tool deflection, heat, and premature wear are common challenges. CNC machining centers in both job shop and production settings are the typical installation environment.

Key Features

• 0.0300-inch corner radius reduces edge chipping and extends tool life in hard materials
• 5-flute variable-pitch design dampens chatter for improved surface finish during roughing
• Tplus PVD coating provides high hardness and oxidation resistance for stainless and high-temp alloys
• Centercutting geometry allows plunge entry as well as peripheral and slot milling
• Solid carbide construction delivers rigidity and precision in tight-tolerance applications
• Compatible with high-precision toolholders for minimal runout at the spindle interface

Compatibility

Designed for use with high-precision toolholders. Primary workpiece materials are stainless steel, high-temperature alloys, and hardened steels. Secondary workpiece materials include steel and cast iron. Part of the HELICAL SOLUTIONS HEV-C-5 series.

Installation Notes

Installation is performed by a qualified CNC machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the 0.5-inch shank fully in a high-precision collet or hydraulic toolholder and verify runout does not exceed the maximum TIR of 0.0005 inches before cutting. Do not exceed recommended speeds and feeds for the workpiece material, and verify coolant strategy is appropriate since this tool does not support coolant-through delivery.
