Pneumatic Bench Sand Rammer, 2-1/2" Round Malleable Butt, 2.5" Stroke, 1" Bore. With dual-action sand wipers, a built-in muffler and a side exhaust, this tool is built for heavy use. Ideal for compacting small sand moulds in a foundry or casting facility. Its shorter height and light weight allow this unit to be used on smaller moulds that are set up waist high. Reliability: Thanks to a built-in lubricator, these tools will run smoothly and last. Durability: With a plated piston and front-end seal to protect your tool, this back-fill tamper can be used in the toughest environments.  The sand-wiper seal prevents dirt and grit from getting inside the tool. Access: This tool is as lightweight as it is powerful, making compact spaces easy to reach.
