  • Powerful, electronically controlled 1'050 W motor with soft start, constant speed, restart and overload protection
  • Precision-machined guide and application surfaces for perfect fit of work pieces
  • Multifunctional stop square for vertical stability as well as perfect mitres due to the application on the outer surface for 22.5 and 45° angles

  • No tool change required for the various connecting fittings
  • Lateral tolerance allows for faster working without positioning aids and stops
  • Avoid errors when adjusting the cutting depth since both work pieces have the same groove depth
  • Proven cutting principle with a disc cutter ensures that the grooves are always parallel and precise, even in the case of knots or rapid working
