Thomas & Betts WT640 Interchangeable Die Adjustable Tool

The Thomas & Betts WT640 Interchangeable Die Adjustable Tool is a manual hand crimping tool that uses interchangeable crimp dies to terminate a wide range of compression terminals and connectors with a single, versatile instrument. Built from heavy-duty steel and featuring an adjustable crimp mechanism and ergonomic grip handles, it delivers repeatable, precisely aligned crimps and adjustable crimp pressure across different dies. Used in electrical utilities, industrial control panels, telecommunications, OEM manufacturing, and commercial electrical installations, it is commonly employed by maintenance electricians, utility technicians, and system integrators for new installations, equipment maintenance, retrofits, and replacing existing compression crimp tools. The WT640 is die-dependent in its compatibility, supporting compression lugs, terminals, splices, and connectors via an interchangeable die system, and is manufactured under the Thomas & Betts (ABB) brand. Common replacement dies include WT112M, WT145A, and ERG4001.
