RESEARCH AND DEVELOPMENT
Flex exerted in the lower section of a drill bit is the most likely destructive factor. The progressive core of the spiral adds material and increases the rigidity in this area which is subjected to extreme pressure.
6 asymetric cutting edges reduce the risk of blockage when in use on a particularly hard aggregate, or on rebar.The progressive core and the roundness of the flute allow optimal removal of dust and negates any risk of blocking due to dust accumulation.
The hardness of concrete combined with the power of the drill unite to create compression. The heat treatment of the body allows the energy of the drill to be concentrated on the tungsten carbide tip (whilst absorbing shock waves).
