Helical Solutions 83153 Corner Radius End Mill 1/2 in 6 Flute

Product Description

The HELICAL SOLUTIONS 83153 is a solid carbide corner radius end mill engineered for aggressive roughing operations in stainless steel, high-temperature alloys, and hardened steel. It measures 1/2 inch in diameter with a 0.03 inch corner radius, a 5/8 inch length of cut, and a 2.5 inch overall length. The 6-flute, variable-pitch geometry reduces harmonics and chatter during heavy material removal, while the chipbreaker profile breaks chips into manageable segments to prevent recutting. A PVD-applied Tplus coating provides thermal resistance and edge lubricity. This tool is installed and run by machinists and CNC programmers working in production and job-shop environments.

This end mill is part of the HEV-C-6 series, which is designed specifically for stainless steel and high-temperature alloy applications including superalloys and titanium. The stub flute length and straight cylindrical shank make it well suited for short-reach, high-load roughing passes on vertical machining centers and horizontal mills. It is a single-end, centercutting tool, meaning it can plunge directly into the workpiece. Compatible workpiece materials also include cast iron and non-ferrous metals. The 1/2 inch shank diameter fits standard ER and hydraulic toolholders; the manufacturer specifies use with high-precision toolholders for best runout performance.

Key Features

• Variable-pitch flute spacing reduces vibration and chatter during roughing cuts
• Chipbreaker geometry segments chips to prevent recutting and improve evacuation
• Tplus PVD coating delivers thermal and wear resistance for stainless and high-temp alloy machining
• Centercutting design allows direct plunge entry without a pre-drilled hole
• Right-hand cut, right-hand helix with helical flute profile for efficient chip flow
• Tight tolerances: mill diameter -0.0020 to 0.0000 inch, corner radius -0.0020 to 0.0020 inch, TIR max 0.0005 inch

Compatibility

Designed for use in high-precision toolholders. Primary workpiece materials are steel, stainless steel, and cast iron (ISO material codes P, M, K). Secondary workpiece materials are non-ferrous metals and superalloys including titanium (ISO codes N, S). Part of the HELICAL SOLUTIONS HEV-C-6 series for stainless and high-temperature alloy applications.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and the tool is secured in a clean, high-precision toolholder to maintain runout within the stated TIR specification. Verify tool projection and stick-out before running the first pass, as stub-length tools are sensitive to improper seating. Follow the tooling manufacturer and machine OEM guidelines for feeds, speeds, and coolant strategy when cutting stainless steel or superalloys.
