With diameters ranging from 5mm to 32mm, in lengths of 110mm to 1000mm, the ST4 4-cutter drill bits use an automated copper soldering process to adhere the high quality tungsten carbide tips, giving them added strength. This allows them to perform on tough applications such as concrete, bricks, blocks and natural stone.
