ABSTRACT:
A composite split head percussive tool including a rigid load bearing framework which carries a non-load bearing head assembly. The non-load bearing head assembly comprises a pair of axially aligned split heads that are interconnected to each other by an elastomeric link. The elastomeric link is encased and fixed within the tool body. During use of the tool, the elastomeric link acts as a dampener that suppresses the struck end rebound of the tool. When one head is struck against a surface, the elastomeric link allows the unstruck head to move toward the struck head and provide a secondary blow that inhibits the tool's struck end from bouncing away from the surface thereby providing the hammer with a unique "dead-blow" characteristic.
