The peeler of this hammer is round like a ball, while the face is flattened like the other hammer. It is used for marking, chipping, light bruising etc. Ball peen is most commonly used in riveting.
The goal of the rivet is easily spread around the ball pean due to rounding.

They are of the following types
  • Raw Leather Hammer
  • Mallet
  • Nylon Hammer
  • Plastic Hammer
