The DONGCHENG HD100101 16 OZ (about 450 g) Ball Pein Hammer is made for mechanics, fitters, fabricators, technicians, and workshop users who need a solid, versatile hammer for everyday metalwork. The flat face drives punches, chisels, and pins, while the rounded ball end is used for peening, shaping, and setting rivets. At 16 oz, the head carries more striking power than the 8 oz model (HD100100) and is still comfortable to swing for extended periods.
