Anybody that works on anything should have the 5 inch pair in their pocket. They are unbelievably capable for such a small tool. These and the regular 5 inch Cobra plumber's pliers are practically a toolbox in your pocket.
To the doubters: yes, you can break a bolt like that. There are different grades of bolts with wildly different strengths. It's actually fairly easy to shear a lower grade bolt when you've got a foot of leverage on it. You can take a guess that he's leaning into the turn and making 200lb of force at 12 inches, that's a 7/16 bolt, so about 4000lb rotational torque on the bolt shaft. I don't see lines or markings on it so it's a lower end bolt. If the bolt had a six lines on the head above each corner, it would be a grade 8, the type normally used on wheels and mounts. A grade 8 is not breaking like that.
Torque is a rotational force applied at a distance, and 1 foot pound of torque is 1 pound of force applied at a 1 foot distance from the centre of the object being rotated. So if this guy was 200lb and could exert an additional 100lb by pushing, this would total 300lb, and his pliers are 12 inches (or 1 foot). He would be applying 300 foot pounds of torque. How did you come up with 4000lb of torque? This guy isn't putting out any more than about 400 foot pounds of torque.
Had these for a few years now and I love them. I'm a commercial plumber and it's my go-to for a tool that size. Never use my 10" crescents anymore. Recently learned they make minis too and that's gone right on my wishlist.
@@joseages2571 I've got the 10" ones, our finish guy has the small ones honestly whatever crescent you use the most just replace with one of these you won't regret it.
I just got an extra large pair of pliers wrench 16 inch and that got me to a union fitting that I could not get my pipe wrench on due to bolts that were too close to it this union fitting, it fit right in there and got that thing loose when nothing else could. Knipex for the win!
Amen I think I have 10 different pairs of pliers and finally broke down and bought a pair of these like a year ago. I will never ever touch another pair of pliers unless I have to.
Both 125 cobra and 125 plier wrench? I carry both in my EDC kit. I'm not in the trades so I don't use them much, but every once in a while they come in use.
When I show how tight and how much force are in there I give someone the cobra grip and a paperclip and ask them to flatten the end of the paperclip. then i give them the pliers and ask them to do the same thing. The pliers always flatten the paperclip the grips don't. Personally I love these knipex pliers
@@Robs-shop yeah they are nice I think if I added up the money between the Knipex and the Malco Eagle Grip vise grips I bought which are USA made I think they all add up to about a $1,000 I collected them over time though
Once I got my first pair of cobras I knew knipex was the way to go. Then I tried their 1000v insulated lineup and omg I put all of my kleins and Milwaukee hand tools in my shed and kept the knipex.
I have 3 different sizes of these, and a couple sizes of the cobra pliers. Those two styles can really take care of so many different things. If you do electrical work, check out the combination pliers/strippers.... The ones with the wide nose on the pliers and can do 20awg-10awg... They are amazing. The shears built into them can cut any kind of non-steel cable with almost no effort. Plus, the built in 6-32 and 8-32 cutters are fantastic
Still waiting to see where you show how tight they can grip a bolt. All you showed so far was snapping a weak bolt which can be done with anything that fits the hex head decently
My boss made me feel bad for spending $70 on a set of pliers when Mastercrap has the same ones with a lifetime warranty for $30 and can be replaced. Any time…. Glad I was right lol
Well, the reason they are good is the way it clamps. They act like a lever at the jaws creating a reduction = more force, the only con that I see with them the range of movement with each adjustment so you need to be more exacted to get it to clamp but when they clamp down it's with a lot of force more than what you're outputting with your hand.
Yeah I got that one and it's been nice, kinda eager to get different sizes though and thinking about getting the knipex one to compare them side by side if project farm doesnt
Nah These ain’t a joke They’re also 100% pliers. You can grab and twist something completely round, though just in the right place at the right time I Love how close together the handles Can get while you attach your wrench to the fastener, and the Torque you apply is the torque you get.
i dont know abut that bolt, but that table looks heavy and it moved. and these are "fine working" pliers, use the cobras if you ant more grip. for what these are designed for they are more then strong enough.
I have only bought one of these, and some douche bag went in my box and stole them, put a dead man's initials on them and told me that's where he got the ones I saw, only to figure out they were mine. A little more time and I'll get another pair, still raw from the described episode
I think its ok to pay whatever it takes to have good tools, just if you're going with premium tools be sure to get alot of use of them, not just once in a while.
I love my 5 inch Knipex Pliers Wernch and Cobras that I EDC. That being said, not all bolts are the same, that bolt looks like a grade 2. Try this with a grade 8 bolt. Snapping a grade 8 bolt would be much more impressive.
Manufactured Chinese bolt with no grade marks . The bolt did not even spin against the smooth vise jaws ! Knipex are the very best however this test does not impress .
@@AquaTech225 well the adjustment has to be just right. If not the handles are always to wide. Plus they open up to much when back spinning the pliers for another turn. But they grip great. This is just personal opinion.
Am I the only one questioning the ability of this dude being able to snap this bolt with such little effort? Also, the threads would move in the vice before the bolt would snap simply because of surface area? Was this bolt made of aluminum?
@@dandugo2020 Well, you must be the kind of guy that screams "photoshop" at everything he doesn't understand. Have a great day doubting everything around you.
I found those are just a crescent wrench with extra steps. I do love the pump pliers, but a really wide jaw adjustable wrench does everything the flat jaw will do.
Liar, the bolt has already been cut. Its no where NEAR this easy to snap a bolt of that size. Think about it. A bolt about twice this thick is used to pull trailers behind trucks full of equipment and weighing anywhere from 500lbs to 3500lbs. This guy didnt just snap one with a twist of his little wrist.
Agreed. You can clearly see the double cut just above the screw thread. I own a lot of knipex tools and they are worth every penny. There’s no need to produce fake clips.
