• 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 rock drilling. Extended exposures to handle vibration may lead hand-arm vibration syndrome, causing injury to the nerves, bones, joints and blood vessels in the hand. In this experiment, the team tested carbide-tipped bits in four different states of wear, measuring drill handle vibration and productivity while drilling concrete block.
