I have some RG-59 coax cable and I want to terminate it with BNC compression connectors. I bought some compression connectors, and what I think is a pretty good quality compression tool — the Liberty CM-TOOL. But every time I try one, it cracks the white plastic and bends the metal out around it. I tried to show what I mean in this picture. It sort of makes sense why the plastic cracking; the tool applies a great deal of force to that area. So how is this supposed to work?
