What is the best crimper tool for this heavy gauge connector?

Thank you for your question. The best tool is a crimper for non-insulated terminals. This tool is included in our 5pcs and 8 pcs crimping tool set (Die B). You might also want to have a look at our Crimping Tool for Quick Change Crimping Dies and choose the needed die from the catalog.
