The latest generation of SDS-max® chisels and points feature the newest innovation in demolition steel--reflection technology. Bosch's R-Tec reflection point is featured on HS1903 and HS1904. When energy is dispersed with each beat of the hammer, the new R-Tec point reflects the hammer's energy back into the work material, increasing the rate of removal by 15%. The result is faster demolition which increases overall jobsite productivity and profitability
