999

Rammer has always been at the forefront of hammer development, and the 999 scaler is just a part of the next phase in hammer development for special applications, such as scaling.

Scaling is an extremely tough job for the hammer, and only a specialized scaling hammer should be used.

Features

  • Single lower tool bushing
  • Membrane type accumulator
  • Twin-handed
  • Sound supressed
  • No tie rods
  • CBE+ (Constant blow energy plus)

Applications

  • Scaling
