I own both the Ancor hammer crimper and the FTZ 94284. The FTZ 94284 makes a beautiful 360 degree crimp that is very solid. In testing I have conducted it exceeds US MIL Specs. A full 360 degree crimp makes a truly cold formed connection between the wire and the lug.
I really don't use my Ancor hammer crimper much because the FTZ rotating die crimper is just that much better for not that much more money. The Ancor makes a "dimple crimp" which can damage conductors and still not make the best electrical connection. When I am crimping cables that will start 800HP diesels there is simply no room for a "dimple crimper" in my tool box.
I consider the Ancor tool an emergency, get you home, tool. Nice to own if you have extra boat bucks floating around but not a tool I'd use for my own primary wiring.. Marinco claimed/claims this tool makes a UL crimp. However, when I called them and asked them to furnish documentation of this, or any other testing, there was a complete lull in any data coming out of them. I made three calls and got nothing out of Marinco.
If someone can get this UL documentation, or any legitimate testing data from Ancor/Marinco on this tool, please forward it to me.
As I always say tools are free if you DIY
When you figure that an Ancor hammer crimper would cost you nearly $80.00 and the cost savings in battery cable from a place like Genuinedealz.com is so huge that the high quality crimper is almost no additional expense. This is man math at its best. Do not run this scenario by your spouse.. Wink!
The 94284, which is the non-ratcheting version of this crimp tool that I use, can be purchased from:
