Ferrule crimp tools part deux

[derek]

I've got a pressmaster one, but I work in the water industry where failure is not an option ( unless it is caused by poor design and lack of maintainance because they are/were too busy creaming off profit until they got hit by massive fines).

I think the RS 10/16/25mm is also made by Pressmaster as it is Swedish.

Thanks for that pc1966...very interesting to see that trial.

I have a couple of decent ratchet crimpers for ferrules and terminals, but for fine wires, lighting etc I use a pair of CK plier-type crimpers for bootlace ferrules. They are ideal for the very small sizes, and being compact can be used in tight corners.

I also use the knipex pliers type, and like most things you get used to them and making sure it's in the right slot becomes automatic
My last Firm lots of people frowned on them preferring various ratchet types,

There were some connection problems in panels and wiring connected to them.
One of the Company Engineers decided to test them without anyone knowing
He had some previous extensive experience testing and calibrating crimp tools and connections for the Railway industry.
He picked panels which had been wired by different people with different tools

Most people were surprised at his report which basically said the same as Pc1966 tests
The pliers type were very reliable as long as they were a good make, manufactured to a DIN standard, not excessively worn, they were used properly.

The ratchet types did vary between makes, however some of the cheaper company supplied ones equalled the more expensive, which led to them being banned as there was too much variation in crimp quality

Be still my beating heart. I looked at this topic as it popped up when I started to create one titled "Cheap tools aren't good, good tools aren't cheap", because I have a one-off need to do some cord-end crimping of 4mm² - 16mm² tri-rated for a personal project.

eBay is awash with cheap Chinese POS Knipex look-alikes and I was going to ask if anybody knew if they were a POS in that they just aren't going to work, or a POS in that they aren't going to work for very long.

Looks like you've been a great help to me!

One thing to add is if you are using screw style terminals the crimp only needs to stop the ferrule easily coming off, as it gets further crushed by the termination. But if you use spring-loaded terminals like Wagos or some DIN rails, then you need a good crimp to get a good stable contact between the wire and the ferrule.

@pc1966 Your set is not complete.??

Not yet!
I have a SWA-brand crimp tool like you large one, goes 6-50mm I think. Like this:
