PCBN/PCD Small Helix Angle End Mill

The PCBN/PCD Small Helix Angle End Mill is designed using a low-angle, relatively flat blank to approximate a helical cutting edge. It is specifically engineered for machining cast iron, non-ferrous metals, and high-hardness non-metallic materials. Featuring a small helix angle structure of 2°-6°, it can be ground with a helical relief angle, achieving a gradual engagement effect during machining. The PCBN grade is suitable for materials like cast iron and powder metallurgy, while the PCD version focuses on high-silicon aluminum alloys and non-metallic materials. With specially reinforced cutting edges and an optimized rake angle design, it enables micro-cutting processes for thin-walled parts, maintaining exceptional stability and tool life for highly efficient finishing operations.

● Excellent Design: The small helix angle structure provides a helical cutting edge, enabling smooth and stable cutting.]
● Stable Machining Performance: The small helix angle ensures stable cutting loads, allowing for precision machining of thin-walled parts.
● Long Machining Life: Optimized edge preparation technology combined with PCBN/PCD super-hard materials delivers an ultra-long tool service life.
