The Pro-Point screw has a Speed + thread that makes ice screwing 20% faster than with a standard thread. Cutter tip = Provides a lower torque while reducing the risk of cracks. Saw teeth = Cuts off the wood chips neatly Stem cutter = Cuts away and transports the chips, which leads to a maximum joint. Grooves = Provides a neat countersink Waxed = Reduces the tightening torque and further increases the rust protection. This saves both machine and battery The screw also meets the requirements for C5 in which means that the screw has a higher corrosion protection than the normal C4 classification that other brands have.
