Downcut Spiral CNC Router Bits
Shop ToolForm UK’s range of downcut spiral CNC router bits, designed to deliver exceptionally clean top edges when cutting wood-based sheet materials. The downward cutting action pushes fibres and veneers into the material, helping to minimise tear-out on the top surface.
