DRILLING A pneumatic drill or jackhammer is a portable percussive-drill, operated by compressed air and used to drill rock, break up pavement, etc. It works in the manner of a hammer and chisel , by jabbing with its bit, not by rotating it. A drill, driven by compressed air, which rotates its cutting bit is called an air-drill or, more familiarly, a windy-drill. The word jackhammer is used in the North American English and in Australia, whilst pneumatic drill is used elsewhere in the English speaking world. The sound of the repeated hammer-blows combined with the explosive exhaust of the air, makes pneumatic jackhammers dangerously noisy, emitting 100 decibels at two meters. Sound-blocking earmuffs must be worn by the operator to prevent a form of hearing damage of which tinnitus is the main symptom. Also, prolonged exposure to the very pronounced vibration set up by the tool can lead to blood-circulation failures in the fingers. skate and shooting drill take it from the corner along the boards and around the assistant and back down the center for a shot on goal Similar posts: hockey experts locations ice hockey skate blade espn hockey score power skating hockey camp under 18 hockey results canucks hockey radio hockey news and rumors |
