You are buying a crimping tool for UN-INSULATED auto electrical terminals.
Tool gives a "fold-in" crimp (See images)
The tool has a built-in cable stripper, cable cutter and a five hole bolt cutter (for bolts from M2.6 - M5).
This tool is suitable for use with the terminals we supply with our 5 pin relay bases (both micro and standard), Mate N Lok, SuperSeal & multi-way connectors.
This tool is NOT for use with PRE-INSULATED terminals, we have suitable PRE-INSULATED crimp tools (ALT/TT304)
We also offer a similar tool, ALT/TT71 but with heavier duty jaws and equipped with a spring return handle feature
