16 17 FROM Ø5 TO Ø7 3 cutting edges for ø5 to 7 mm because it requires less effort in terms effort in terms of power and number of cutting edges. It is also necessary not to overload the insert at an angle on these small diameters afin not compress the dust and ensure that the dust is evacuated evacuation. 3 CUTTING edges for optimised dust evacuation Central areas Peripheral areas 3 central cutters with a 130° angle start the hole and guarantee centring and penetration. 3 peripheral cutters at 145° take over and complete the work with a concrete-breaking effect. Optimum distribution of the 6 cutting edges for better better distribution of force, ensuring uniform wear of the cutting edges and longer service life. The combination of these 6 cutting edges ensures maximum of concrete in the shortest possible time. 6 CUTTING edges for optimum destruction of concrete in minimum time FROM 8 TO Ø20 PASSES THROUGH CONCRETE REINFORCING BARS WITH EASE Christophe Salin AD SARL salina Jura solar energy “ ”
