Explosive+Power+Tools+-+EPT's

Explosive Power tools are also known as **Powder Actuated Fasteners** There are two main types of tools: 1. **Direct Acting** type that propels the fastener down the barrel of the tool in free flight just like a bullet. 2. **Low Velocity** type that, when the charge is fired, propels a captive piston down the barrel pushing the fastener into the materials. This means that the full force of the charge is transferred to the fixing only until the piston stops moving. Follow the link for a demonstration. http://www.ramset.com.au/flash/vel_principles.swf
