Michigan Pneumatic Tool, Inc. announces the new MP-241B, the most powerful bench rammer for industrial use. Delivering 760 blows per minute with a bore of 1-5/16 inch and a stroke of 4 inches, the MP-241B is the most powerful bench rammer in production today. The MP-241B features a unique double-action "sand wiper" seal to exclude dirt and grit from inside the tool for reduced wear and long life. An aluminum backhead reduces weight and operator fatigue, and a hooked lever throttle improves operator comfort. The rubber butt is replaceable.
