Square End Mill
Square end mills are widely used carbide tools for CNC machining, designed for slotting, side milling, shoulder milling, and contouring. With a flat cutting edge, they deliver sharp corners and precise dimensional accuracy across a wide range of materials, including steel, stainless steel, cast iron, and non-ferrous metals.
Key technical features include optimized flute count (2F, 3F, 4F, and multi-flute designs), variable helix angles for chatter suppression, and high-performance PVD coatings to enhance wear resistance and thermal stability.
Our carbide square end mills offer excellent rigidity, stable chip evacuation, and extended tool life for roughing and finishing. Popular models include general-purpose, high-efficiency machining (HEM), and variable pitch end mills, with options for customized geometries, coatings, and dimensions to suit specific machining needs.
