Recommendations on a crimper?

I'm going to have a LOT of electrical work in my near future, with a lot of crimping involved. I just bought a new, relatively inexpensive crimper on Amazon, and picked one that was advertised for "insulated terminals" - but it still doesn't seem to be a good fit for the typical connectors that I'm using.

I'm planning to use ring terminals and butt connectors, ideally the really good ones that have adhesive in them, and heatshrink.

Is there a "good", "reasonably priced" (maybe under $50), "ratcheting" crimper that I might be able to find on Amazon or similar that will work for this?

Especially for the small ones, I can get the job done with a pair of vice grips - but I'm sure there's got to be a much better answer than that... And I'm curious to see how much groaning and grief I'll get over even mentioning vice grips!! <grin>

John

There are many choices on Amazon for ratchting wire terminal crimpers. $15 and up.

Choose one based on customer reviews and feedback.

I would have a look at https://marinehowto.com/marine-wire-termination/

While you can definitely get cheaper ones, if you are doing a "LOT of electrical work" in your near future, it will be worth it to spend money on the tool you'll be relying on. I personally use the Ancor models for both non-heatshrink and heatshrink connectors, and I believe they are easily $100 or more each. But I've had them for 10 years, and they just keep on going.

This is the one I bought - but it doesn't do well with normal connections. It looked good in the ad. And it's reasonably well built, solid enough, cheap enough. Just not the right jaws for the type of connectors I'm using...

That appears to be for ferrules, not ring terminals and the like on a boat. Unless yours uses ferrules into a Wago block or something like that.....

Good article Steve,

I have an Ancor ratcheting crimper too. I also bought one from Newark Electronics when they were called MCM Electronics for less than $20. They appear to be identical and they have been in use for over 25 years without issues.

This one does the three most common wire sizes and is very robust.
I bought it at an electronics hobby store at least 17 years ago for under $50.

Right here. Screw Amazon. This is a great source for all your electrical needs.

A good crimper like this is worth paying for, I am grateful for not having got a cheapo.

I found one of the better quality ratchet crimpers with 4 sets of dies for various terminals used on eBay.
Worth a look. One would have to use them for a long time to wear one out.
It's worth getting a good one and the Compass Marine site is a good one. Check out his crimpers he sells and if close to comparable why not throw a little business to a regular contributor (CM) here on TF.

I use an ancor crimper, runs $80-$90. It works well with their brand of double crimp terminals.

I started using Klein tools after an electrician friend introduced me to them. Here's one of their ratcheting crimpers.

My understanding from CM and my brother that does as fair amount of elec work for other boaters is it depends on whether you are using shrink type or just the common insulated terminals/ butts.
For a decent inexpensive crimper for shrink terminals here's one worth considering. Similar to CM CM recommended one.

One thing to note (it is explained in the marine how to article) is that there is one type of crimper (double) for nylon insulated terminals, and another type (single) for the type that have included heat shrink. You can't interchange.

Ironically, the "double" crimpers always look much more "professional," at least to me; whereas the single crimpers look kind of thin and wimpy. However, to my mind, the heat shrink type of crimps are better, and those do use the single crimpers. I just mention this in case you are using double crimpers on heat shrink terminals.

This is what I have had for about 20 years and it works great. I do a lot of electrical work and use the heck out of it.

For small sized wires the ancor is great , but sometimes a crimper for cable 00 to 04 is required,

With loads of time simply ordering the cable with ends installed is easiest and not costly.

Our fall back is the rigging crimper used to set nicropress cable ends.

We have set heavy terminal ends that way and on cutting them open have found the cable to be made both mechanically and electrically , just what is required

IF wiring an entire vessel heavy , say 10ga rather than 10, 12, 14 , 16 in a large coil is less expensive than multiple coils and has less voltage loss.

These, used with non insulated connectors are pretty foolproof. I have a couple brands. The ones with the smooth profiles are nice too. Buy a bunch of sizes of quality adhesive heat shrink and you have the best of both worlds.

Better may or not exist, but joints made this way will easily go multiple decades.

Whatever crimper you use, only buy quality terminals.
