This Draper single hammer butterfly air impact wrench is manufactured with a lightweight aluminium housing. The compact size helps in tight spaces making it ideal for transmission, body panel, exhaust system & small engine repairs. The unit has a one-handed forward & reverse butterfly control with built-in regulator to vary speed & power. The wrench has a side exhaust & a 1/4" BSP airline connector that connects with the 360° rotating air inlet, helping prevent air-lines from kinking when in use.
