This three piece set includes a thick vulcanized firm rubber base which absorbs shock, plus a solid steel block that is 15/16" (24mm) thick and 3" (75mm) in diameter. The third piece is a sturdy nylon block the same size that fits into the rubber base for lighter, more delicate work. This is a well made set, and allows one to hammer without creating excess noise and vibration at the bench. 2.5 lbs.
