Pneutorque Pneumatic Torque Multiplier-Image

PTM-72 tools use the same 'twin motor' handle as the PTM-52 but fitted with a durable 72mm gearbox to allow higher torque outputs. The 'twin motor' concept gives the benefit of high run-down speeds while adding very little to the size and weight of the tool.

Also available as Internal and External Control, Shut-Off versions.
