One of the new products you can check out at the outdoor Bosch booth at the 2011 World of Concrete are the new R-Tec Concrete Chisels. Bosch is replacing its SDS-Max flat chisel and pointed chisel with new more powerful chisels which offer the professional user considerable advantages. The R-Tec reflective element (cone shape in middle of the chisel) increases material removal rate by up to 15%. This is achieved by converting the recoil energy into additional impact energy, therefore considerably increasing the material removal rate while reducing vibration. Both chisels also have a self-sharpening cutting edge, which enables them to achieve a constantly high material removal rate. It also saves time by eliminating the need for time-consuming chisel resharpening.
The new SDS-max R-Tec 1” Flat Chisel HS1936 ($15, Ohio Power Tool) has a cutting edge twice as long as that of a standard 1” chisel, which doubles the material removal rate. On the new SDS-max R-Tec Bull Point Chisel HS1935 ($18, Ohio Power Tool) the “blast spin” action of the optimized cutting geometry enables continuous work without jamming in the concrete. At nearly the same price you will pay for any other 16” chisel these are definitely worth consideration.
