Spirals

Spiral router bits are among the most essential tools in any CNC operation. The helical flute geometry provides smooth, continuous cutting action, efficient chip evacuation, and reduced heat buildup during high-speed runs. This category covers the full range of spiral cnc bits: upcut, downcut, compression, and mortise compression, in both standard and premium carbide grades. Upcut spirals pull chips away from the workpiece and are ideal for through-cuts, downcut spirals press fibers down for a clean top surface, and compression bits deliver a clean finish on both faces simultaneously. These tools are widely used for cutting hardwood, plywood, MDF, plastics, composites, and non-ferrous metals.
