FEIN POWER TOOLS UK says as an inventor of the electric power tool, it is proud to have served British industrial workers for 30 years. Whilst the manufacturer is a father of electric power tools, and following a cordless evolution now offers a large range of cordless tools to the industrial sector, the company says one of its bestselling machines to this day remains a pneumatic pipe saw. Not only that, but the pipe saw remains relatively unchanged from the initial model sold some 30 years ago, with only the air motor receiving minor adjustments during the last generation of machine.
