Thanks, I wondered why it came out like that, time out got to the first post unfortunately, perhaps one of the mods can edit it?

I've got the ones that Mike linked to, can't fault them and won't break the bank

This bad boy has just arrived, let's go crimping!!
Not sure how they produce and ship all this for 19.99 but there you go

I've got the vlike ferrel crimper, seems ok & ive had no issues with it. It goes upto 10mm.

We often need to use ferrules on 0.25mm cables for control stuff, and the cheap eBay special self-adjusting crimper was not doing that OK. Fine for 1mm and above, not so great below.

I discovered that the fancy RS hex-profile crimper:

RS PRO Hand Ratcheting Crimp Tool for Wire End Sleeves, 0.14 → 10mm² Wire | RS

Is made by the Swedish company Pressmaster and is available here at a slightly less eye-watering price (RS about 25% more expensive):

Pressmaster 4300-4662 Proteus 10H Self Adjusting Crimp Tool Hex 0.14-10mm²

(unfortunate choice of name for the UK market!)

Got one today and very pleased with it. Does a really good job with the smaller ferrules and comfortable to use. Realistically it is difficult to justify the x10 cost compared to the Chinese versions for most users that have occasional use of the 1-10mm sizes, but if you really need it to work well over the whole range it is a good investment.

At that cost, I think I will stick with the one I posted earlier, crimps to closed, so may do the fine wire you are talking about, the white ferrels are 0.5mm?

The ones I'm using are violet.

Yes, it is hard to justify cost over the ebay/amazon ones, but they do work really well.

White is 0.5mm², yes. Violet 0.25 surely? Both French code.

How do the hex versions fare in cage-clamp terminals? I use the square intermeshed kind from Pressmaster, which leaves the ferrule square and crinkly. I sometimes find with the smaller cables it is rather too crinkly because it applies too much force; is that the problem you had with the Chinese one?

Probably. Whatever we usually get from RS...

Not played with it enough for that yet, but usually a larger cage-clamp at recommended torque flattens out the ferrule anyway. In that sense crimp force is less critical.

The problem I had was the cheap one was not crimping it enough to hold the wire reliably before they were tightened down. Seemed OK much of the time for 0.5mm, and great for 1-10mm, though I have a better one that does 10, 16 & 25mm

So really I have used the cheap one mostly for 1.5, 2.5, 4 and 6mm.

It appears to have an adjustment, but the screw holding that in place was so tight that the head cammed out attempting to loosen it to see if it could be adjusted. That was the point when I decided to calm my inner Aberdonian, get a good one, and stop messing around.

but are they any good on meter seals? ?

What are meter seals?

 

[pc1966]

Violet 0.25 surely?

Yes, we use 0.25mm which is the biggest problem for the cheap ones.

They do work on meter seals but leave a pattern in the seal
