We can manufacture molded urethane hammers and sledges featuring a semi-hollow head casting partially filled with iron shot designed to transfer a more powerful and solid blow. Custom molded polyurethane hammers and mallets for all industries. The urethane offers a non-sparking head and superior life to rubber hammers and mallets. Urethane mallets protect the operator from rebound or impact sting. They won't chip or splinter, and they resist petrochemicals and wear. Urethane mallets can be used on materials including steel, iron, brass, aluminum and wood. Common industries served include HVAC, machine shops, refrigeration, oil refineries, sheet metal shops and furniture.
