The Bi-Directional Pneumatic Air Hammer/Puller, No. LT955AH, from Milton Industries, offers up to 3,000 blows per minute. A vibration dampener reduces user discomfort and fatigue, and an adjustable brass air flow regulator allows users to control the tool's power to handle a variety of tasks. When its piston air lock plug is inserted, it converts the tool from an air hammer to a pneumatic puller. Either way, the tool can be operated with one hand, allowing technicians to hold or adjust parts with their free hand.
