• Description:
  Rotary hammers and hammer drills are used extensively in commercial construction for drilling into concrete for tasks including rebar installation for structural upgrades and anchor bolt installation. A CPWR-supported research team has developed a test bench for standardized measurement of dust, noise, force and vibration during concrete drilling. In this experiment, the team tested three drill bits in different states of wear, measuring silica dust, noise, and productivity while drilling into concrete. See abstract: http://bit.ly/2fZi3YH.
