TEKTON dead blow sledge hammers have steel shot inside the head of each hammer to reduce the post-strike rebound that is common with other hammers and mallets, allowing for better-controlled hits to the workpiece. The hot-cast polyurethane jackets are highly resistant to chipping, cracking, and tearing. The contoured handles and their textured surfaces provide a comfortable, nonslip grip for hammering. The flared ends of the handles help prevent them from slipping out of your hands. A flat section on the top of each head lets the hammer stand handle-up to keep the handle off the ground and makes it easy to pick up when you need it again. This set includes 156 and 200 oz. dead blow sledge hammers.
