PrecivaBootlace Crimping Tool Kit, 0.08-16mm²/AWG28-5 Ferrule Crimp Toolkit with 1200pcs Connectors(300 Dual Wire Terminals), Self-Adjsutable Ratchet Crimper ToolKits

Have you have ever seen the cable ends inside various things that have the little brass or tin bootlace ferrules fitted to the cables? I always thought how much neater and safer that looks because it practically eliminates the chance of strands of fine cable that you can hardly see, shorting out connections. This tool allows you to fit those ferrules yourself.Be aware that is ONLY designed for bootlace ferrules so don't buy it for any other type of connectors.The tool itself works perfectly and it makes a very strong and secure connection to the cable with very little effort. The ferrules have a bell type entry so they really help to guide the cable in nice and straight all the way to the insulation so no conductor is visible. If the ferrule is a really tight fight a little twist and it will glide right in. I can't pull the crimped ferrule off the cable no matter how hard I try. The cable will always break before the ferrule comes off.You can adjust the crimping force by removing the locking screw and rotating the adjustment dial. Just for clarity when I say crimping force I mean how tightly the ferrule it attached to the cable and not how much pressure you need to apply to close the crimpers. Obviously if it takes a lot of strength to close the crimpers they must be crimping on the cable very tightly. While the screw makes it a little fiddly, it should mean that once set to your liking it most probably won't ever need adjusting again.The tool I received, tightened the strength of the crimp on the cable the opposite way to the arrows stamped on it. So I had to rotate the dial to the - to increase the strength of the connection and to the + to decrease it. So just be aware that that could be the reason why some people don't get a strong crimp and the ferrules can be pulled off.This kit comes with 1200 ferrules to get you going. I would have liked some twin entry ferrules in a couple of sizes instead of some of the tiny ones, but is represents great value for money as it is so I'm not complaining.It would be great if I could get the ferrules with different coloured insulation in each ferrule size for live, neutral and earth etc. but so far I haven't found anywhere that sells them that way so I apply insulating tape of the correct colour instead. If you know of somewhere that sells them, please let me know.A little tip I recommend is that when buying extra ferrules yourself in whatever size you use a lot of get 10mm length or more and cut them down with your side cutters rather than having to buy different lengths. Then you can get the ferrule in all the way to the insulation creating a really nice looking connection.

I've been building some panels for a new customer, who requires ferrules to be crimped with square (four jaw) crimpers. That meant that my £50 CK tools crimper was no good for this job. This Preciva one was the cheapest 4 jaw crimper I could find delivered at short notice.Its a great bit of gear, seems very high quality. I intended to only use it for this one customer/job, but I'm going to use it for all ferrule work going forward.Things I like about it:+The crimped ferrule has a square cross section, much easier to insert into terminals than the C shaped section that the CK one (and all "old school" crimpers) leave. See photo for comparison.+It only has one position no matter the size of wire. My CK one has multiple slots on the die depending on what size wire you are crimping. This one is so much less faff to use, especially when dealing with multiple wire gauges in quick succession. Also stops the apprentice using the wrong size and over/under crimping one.+This Preciva one also does 0.08 to 6.0 mm, whereas my CK only does 0.14 to 2.5 mm!+The ferrules it comes with seem good quality, and the zip case is great. Nice to have it all together, and keeps the ferrules from spilling in my tool bag.+It doesn't ratchet, which is actually good in this case ,as this four jaw type requires so little pressure to crimp compared to the traditional type.Really can't fault this. I've already recommended it to my colleagues. I'm a bit peeved that my CK tools one is going to be retired, considering it was over twice the price of this one, and it didn't come with a case or ferrules!I've only had this for a week, and we have already crimped approx. 1000 ferrules with it. I'll update the review in a couple of months if I have any problems with longevity.

Quality is better than expected from this budget brand, ideal for DIY or infrequent use for tradesman. Still working after few months and doesn't feel any different from first time i used it. Good sturdy product
