Hand Held Scabbler|multiple heads
These are the lightweight and compact tools, equipped with tungsten-carbide tipped pistons. The pistons oscillate inside the head or cylinder of the scabbler and strike the surface of the material being worked on. All the scabblers have three pistons mounted in line.
The cycling of the pistons occurs due to the air porting arrangements in the piston assembly. The machines are examples of a valveless piston motor.
