CNC router tooling refers to the various cutting tools used in a CNC router machine for shaping, carving, and cutting materials like wood, plastic, and metal. Common tools include end mills, which are used for general cutting and come in flat or ball nose shapes for smooth finishes or 3D contouring. V-bits are ideal for engraving and creating detailed, sharp lines, while compression bits combine up-cut and down-cut flutes to ensure clean cuts with minimal tear-out. Drill bits are used for accurate hole drilling, and spiral bits provide smooth cuts with efficient chip removal, often tailored for wood or clean edge work. Tapered bits are designed for precise carving and edge profiling, perfect for detailed work.
