Bootlace Ferrule Crimping Tool, Preciva 0.08-16mm²/AWG 28-5 Ferrule Crimper-Tool with 1200pcs Ferrules, Self-Adjsutable Ratchet Wire Crimping-Tool,Wire Terminal Device Set

I bought this Preciva bootlace ferrule crimping tool, and it works perfectly. The self-adjusting ratchet mechanism makes crimping easy and ensures a tight, secure connection every time. The hexagonal crimping design provides a professional finish.The 1200-piece terminal set is a great bonus, offering a variety of sizes for different wiring jobs. The tool feels well-built and comfortable to use, even for extended periods.Overall, a great crimping tool for electrical work. Would definitely recommend!

Stunning tool for the money.

Worked perfectly for 3 months. Simple to use, did job perfectly saving time, and crimped nicely.But after using constantly all day the spring between each handles snapped off and are no longer saving time on job.

Why use ferrules on cables?The reduce the contact resistance between a terminal and the cable. They also reduce oxidation of the cable as the crimping action and sleeve helps keep oxygen out of the cable.Ferrule ends also are generally easier to insert into a terminal. No twisting or loose strands of wire to worry about.I've used a square ferrule crimping tool for some time now, and it's great in rising clamp terminls, but not so good in round terminals. The square can be deformed easily, and in tight round terminal holes may not fit at all.So I was on the look out for a hexagonal ferrule crimper, and this one fits the bill.As the hexagonal shape is closer to a circle it allows a larger cable to fit easily in a round terminal.Physically the tool is larger that the square crimper, but it can also accommodate slightly larger cable sizes. Certainly this should suit the home user, or even many professionals, accepting up to 16mm2 cable sizes.It arrived neatly packed in a box, but this is just the tool, no storage bag or ferrule assortment.Fortunately I already owned both of these, and there was even enough space in the bag to slip in both tools.The multi lingual instructions are basic, but servicable.Briefly I recommend finding the appropriate ferrule for the cable, the metal part should fit nicely over the cable and plastic boot over the cable sheath.Measure the exposed metal part of the ferrule and strip the wire that much, plus a little allowance.Slide the ferrule over the stripped wire all the way down. There should be some wire protruding from the end of the metal ferrule. If not, strip off some more.Insert the ferrule into the tool and squeeze. This will be a hard squeeze for larger cable, but the tool feels robust and capable.If the ferrule is longer than the jaws, then reposition and crimp again, taking care that the hex lines up, but this is unlikely with this wide jaw tool.Finally, trim off the excess wire protruding from the ferrule, or indeed if the ferrule is longer than the terminal is deep, then trim off the excess ferrule with the wire inside.The tool makes a good firm crimp on all size wires I have tried.So far it feels robust and reliable, and hopefully this will continue to be the case.

I have been meaning to buy one of these for some time.Stranded wires are a pain. In plugs, junction boxes or whatever, even Wago plugs, they just spread out and damage. It is so much better to crimp them before fitting to avoid that damage.This is a good crimping tool. Does the job perfectly and has large jaws for large cables, and accurate jaws for small cables.A little bit more expensive, but you only buy on once. Recommended.

Although a budget tool it has the feel and operation of a higher quality product.

Well layout crimps box with labels. The crimping tool does a good job for the all sizes and NO ADJUSTMENT required. Will be good if they put some eyelet crimps in as well.

I found it hard to decide between this criper and a hex Crimper but most of my ferrules were to be clamped into phoenix connectors so decided square was the way to go. This certainly achieves results. I got a 1500 piece ferrule kit with this and started wiring my CNC milling machine driving circuitry. Out of a couple of hundred crimps not a single ferrule is loose. I did increase the force to half on the wheel by the handle as it felt weak from the factory compared to spade crimpers etc. Happy customer
