Diamond blades competition!

Test between standard professional blades against DNA Montolit technology blades. Which is the best diamond blade to cut concrete?
The movies show three comparative tests between diamond blades made with DNA technology and high-quality blades made from standard technology (nb. the 99,9% of the blades now in the market are made with standard technology). The images refer to hand held machine, paving saws and angle grinder and cuts have been implemented on a slab of concrete vibrated. In addition to the greater speed of DNA technology there is also a significantly longer duration and consistency of performance that this technology offers relative to the achievement standards.
