Hammer Crimper for Battery and Welding Cables

This Klein Tools hammer crimper handles uninsulated lugs from 8 AWG up to 4/0 AWG. It is built for electricians and technicians who terminate heavy battery or welding cables on site or in the workshop. The indent-style crimp and V-groove base hold the connector securely during each strike.

Requires a Sledgehammer or Vise for Operation

The tool does not generate force on its own; it needs a 2 to 4 lb sledgehammer or a shop vise to complete the crimp. Users without access to a heavy hammer or a bench vise will not be able to use this crimper effectively. No hydraulic or ratchet mechanism is included.

Crimps 8 AWG Through 4/0 AWG Uninsulated Lugs

The wire-gauge range is the single specification that determines whether this crimper fits the job. It covers eight consecutive sizes from 8 AWG to 4/0 AWG. If the cables fall outside this range, a different crimping tool is required.
