Created from two hardnesses of urethane, the faces on this heavy forming hammer deliver the power of hydraulic force to shape metal. Each head conforms to the surface being struck, spreads out across the metal, and then bounces back to its original shape. It delivers the force to more than 14 times the surface area as an ordinary plastic-face hammer, creating shapes with far fewer strikes than a traditional hammer. The cross-peen face is made of extra-hard 95-durometer urethane and tapers to a 32 by 1 mm tip. The flat face is made of 80-durometer urethane, 32 mm in diameter. The flat face can be unscrewed and replaced with different urethane hardnesses and shapes. The head of the hammer is anodized aluminum; the handle is made of tough, durable hickory wood. Additional inserts are available separately. Supplied by: Rio Grande
