Magnetic drills machines are ideal for drilling structural steel and virtually any metal. Pneumatic magnetic drilling machines are used in oil and gas industry in order to avoid sparks and special tube magnetic drilling machines are used that could be fixed on pipes of different sizes, even inside.
Broach cutter uses a machining process called broaching that uses a toothed tool to remove material. Broaching is of two types: linear and rotary. In linear broaching, the broach is run linearly against a surface of the workpiece to effect the cut. However in rotary broaching, the broach is rotated and pressed into the workpiece to cut an axis symmetric shape.
