KNIPEXSelf-Adjusting Crimping Pliers for Wire Ferrules, 0.08-16 mm², Square Compression, Crimping Tool, Wire Crimper, 97 53 04

I bought these to replace a cheap pair I had that broke. They work all the way down to 0.08mm and up to 16mm bootlace ferrules, cheap pair only did between 0.25mm and 6mm. These ones also give a nice square crimp that can help them fit into some devices whereas my previous pair did an oblong crescent like crimp that sometimes were too wide to fit the same device. They are a bit pricey but Knipex is a brand I have trusted for the past 12 years as they are of a quality build.

Works fantastically. Used in anger on a whole house rewire, everything from 1mm2 to 10mm2 stranded cables. You do get what you pay for, much better than my last set of crimps.

I have used these for a few months now and they are the best crumpets I have owned. The list price is rather expensive, but unless you lose them they appear extremely well made and come with a warranty so should be good for a number of years

Great product easy to use and great quality

Best indeed

A lot of money but faster than pliers type bootlace crimper, bootlace ferrel does not get stuck in one half of die. If you have 100s to do, go for it.

Really good and well made but expensive

Returning this crimper, as it does not crimp pins on to 0.22mm² 4 core control cable we use for temperature sensors. Althou it states that it crimps 0.08 - 16 mm² cable. Pins fall off and you have to crimp them over and over 5-6 times to stay secure. Not what I was expecting from a tool that cost this much! Never had any problems with a same design £20 crimper. I have a lot of knipex tools and this one does not do what it says on the tin! Not happy...
