These cutters have a bearing guide located on the shank, negating the need for a guide bush when following a template. The bearing is the exact same diameter as the cutter, simplifying the process when making a template. No calculations are necessary, as the workpiece will be an exact copy of the template. Axcaliber router cutters are high precision tooling, made using advanced technology on multi axis CNC machines. A high shear-cut angle gives them a smooth cutting action and results in a clean finish. The tips are diamond-ground micrograin tungsten carbide. PTFE coating minimises resin build-up.
