NPK K3JR

NPK Demolition Shears are engineered and manufactured to world class standards to deliver optimum productivity on the most demanding demolition jobsites and steel processing operations.  K3JR demolition shears are suited for skid steers, backhoes, and mini excavators within the recommended carrier weight ranges listed in the specifications below.  


The unique construction of the arm pin prevents distortion of the main frame and diminished jaw deflection, this in turn maintains blade tolerances preventing jamming of material between the cutter blade.

  • Waved shape cutting blades for superior grip and control of material
  • Unique design that tightens frame and arms to prevent distortion
  • Full 360° power rotation
  • Low weight with large jaw opening
  • Slim line design to increase visibility


NPK dedicated mounting kits enable demolition shears to be mounted as:

  • backhoe attachments
  • mini excavator attachments
  • skid steer attachments


Potential applications include:

  • C&D recycling and/or sorting
  • Cutting rebar, pipes, beams, and other C&D scrap
  • Commercial demolition projects
  • Many more
