The DONGCHENG HD100102 24 OZ (about 680 g) Ball Pein Hammer is made for mechanics, fitters, fabricators, technicians, and workshop users who need extra striking power for tougher metalwork. The flat face drives punches, chisels, and pins, while the rounded ball end is used for peening, shaping, and setting rivets. At 24 oz, the head hits harder than the 8 oz (HD100100) and 16 oz (HD100101) models, so heavier jobs take fewer blows.

Key Features

Dual-purpose head: flat striking face on one side, ball end for peening and riveting on the other
24 oz / about 680 g head weight: more striking force for heavier work
Hardened striking face: [confirm] for durability and resistance to chipping
Handle: [confirm, e.g. fibreglass / wooden / steel with rubber grip] for a secure, comfortable hold
