bootlace ferrule crimper

goldie · Apr 19, 2015

Hi guys.
I've seen two types of bootlace ratchet crimper.
They both look to be able to crimp same size ferrules but they look completely different.
One has a four sided square in the middle of the tool and one has jaws that clamp down at the end.
Does anybody know why there are two different types?

The one with the square hole auto-sizes for the ferrule in use within the limits of the tool.

The "conventional" type with jaws, you must select the correct size die in the jaw to fit the size of ferrule you are using.

Great. Thanks.
So basically the square hole type fits all and the other one is to manually select.
If I was to use the manual select conductor size type crimper, should it be crimped multiple times (all the way down the tub) I tried crimping one last week and although it crimped nice and tight it was only covering half of the tube.
Sorry about the vague description.
Thanks again

Also if I have two cores going into one terminal should I use two separate ferrules to to crimp yhe cores or can I twist the pair together and crimp into one ferrule?
Many thanks

That is basically it in a nutshell, mostly either type is wide enough to cover the entire tube of the ferrule, apart from some of the longer types of ferrule, these should be crimped as many times as needed to cover the entire length, both types of tool are not wide enough for these longer types to crimp the entire length in one go.

You can get twin bootlace ferrules for crimping two cables in one crimp.

Perfect. Thanks again.

I've had these for years;

16mm down to 0.5mm, | Crimp tool for bootlace ferrule,16sq.mm |

telectrix · Apr 19, 2015

might go for one of those. my teeth are wearing out.

Darkwood · Apr 19, 2015

At last a question I like to hear .... spent years telling members all fine wire/multi strand cables require ferrules unless they are been terminated into a connected specifically designed for fine wire like a lever clamp style connector...

I take my hat off to you Goldie; if I was wearing one that is!

i prefer the plier type, ive seen too many times worn crimpers being used and the ferrules sliding off the cable

i got them from amazon last year for £25

i would highly recommend them, most rachet crimpers go from 0.25-6mm then from 6mm - 16mm etc

these pliers do the lot and take up a lot less space

they look really good to be fair, a lot cheaper than i was expecting considering the knipex alternative costs £100

telectrix · Apr 19, 2015

Just to add ....
As above 2 cores into one twin ferrule for a "single" terminal ,ie like on a connection to a pcb or similar,

However lots of people do put two single ferrules into double terminals ie as found on contactors
I'm on the fence a little about this as sometimes I find one which slips out but on some equipment it does hold both, also depends on the person terminating cores

I guess there's an argument for both ie two ferrules , its easier to faultfind sometimes as circuits can be split more quickly
And a twin ferrule means there's less chance of losing a connection to a terminal.

Opinions please?

double ferrules have there place bur you should twist the cores together before putting them in the ferrule

Shanky do these pliers crimp everything ie ferrules, butt crimps, insulated and non insulated?

davesparks · Apr 19, 2015

No, they crimp ferrules

Carlosfandango · Apr 19, 2015

Suppose it says it all in the picture!!

no the plastic refers to the handles.

only for bootlace ferrules or endsleeves

edexlab · Apr 19, 2015

The knipex above are very good I've used them for the past 6 years definitely one of the best tools I've bought!
Had ratchets before which although were of good makes always ended up having problems after a couple of years
