The DongCheng HD100402 24 OZ (670g) Claw Hammer is an extra-heavy-duty carpentry and framing hammer engineered for tough construction tasks, heavy formwork, and demanding demolition work. Built with a heavyweight 670g head drop-forged from premium 45# carbon steel, it delivers maximum striking momentum to drive large timber spikes and framing nails quickly with fewer blows.
The striking face and curved claw are precision heat-treated to resist chipping, edge deformation, and claw fracture under high prying forces. Paired with an extended 340mm shock-absorbing two-color fiberglass handle, this hammer provides superior swinging leverage while reducing impact shock and vibration transfer to the user's wrist. An ergonomic, non-slip rubberized grip ensures total control on construction sites.
