Spiral bits produce faster, cleaner cuts in hardwoods, plastics, Corian® and other brands of solid surface materials, etc. 'Up-cut' design expels chips away from the workpiece, allowing for deeper and easier mortising. 'Down-cut' design expels chips away from the router. Premium micro-grain carbide, increased clearance geometry and razor-sharp cutting edges with polished flutes provides a superior finish and longer tool life. |
