The cutters, manufactured in Europe by Colt, may be used to produce dowels or plugs up to 75mm in length. They should only be used in a drill press at low speed, and for the larger sizes a powerful machine will be required. When using, ensure a slow constant feed rate and clamp the workpiece to the machine table. Only suitable for use on solid timber, not man made boards or other abrasive materials.
NOT FOR USE IN ROUTING MACHINES or other HAND HELD TOOLS.
