How does you Knipex Pliers Wrench jaws look like?

I have bough a 250mm one (model 86 05 250) which had a horrible casting seam in the middle of the lower jaw, like the seams on plastics, it as in the middle going along it’s length (I don’t have a photo anymore)
Considering that Knipex prides on selling flat jaws I was surprised to see something like that so bad.

“Smooth jaws for damage free installation of plated fittings – working directly on chrome!”

Not even ultra cheap tools I have bough had any seam on the actual part that touches the bolt, it was the first time I have even seen anything like that.

Then after some time I bought another one (same 86 05 250 model), this one has an obviously ground upper jaw, but the lower one is not ground, which is still fine because doesn’t that an obviously huge flaw like the one I have bough before.

But now I am curious how are the flat portions on your Knipex Pliers Wrench?
Are they flat like roughly flat or flat from being ground flat?

Do they come one jaw ground flat and the lower not ground, that’s the default?

I don’t have that model of Knipex, but post your model number, there are so many variations 8701250, 8801250, and so on that if you are not comparing apples to apples you’re wasting time.

I am interested in info on any of the Knipex Pliers Wrench series, basically the ones that have flat jaws, in the photos I have the 86 05 250.

that may be intentional for better gripping

This model is not intended to have any grip. The smooth jaws protect sensitive surfaces.

Might be a quality issue. I’m a bit dissapointed about Knipex quality (I have 2 pliers and one insulation removing tool). Never had any issues with Wiha tools.

FWIW, not the same model but the Knipex 86-03-250 I have has both surfaces “unground.”

The jaw surfaces are “smooth” and are textured consistent with the rest of the pliers-wrench surface, a sort of sand blasted surface with no seams visible. I use them as large open-end adjustable wrenches (owing to parallel jaws) and for my applications the lack of ground surfaces has not impacted effectiveness.

@Hikelite, on your pair, I wonder if the one side was ground to improve achievement of parallel after assembly?

On the light side.

It is the same series, so it’s great, after all I am interested how they all look in this series of flat jaw wrenches.

I do not know why one is ground and another not, but definitely I would like to know how are these sold in general.

That is what I have thought too, that the smooth surface on both jaws should actually protect the surfaces, since you actually want it to slip on the nut then press on the handles once parallel is achieved.

“Smooth jaw” should be smooth jaw. There should not be any questions here. It clearly slipped through the cracks or the seams. A file or Dremel tool or sanding tool or other should be able to make it pretty smooth pretty fast.

I want to know how these look in general, before going into a long return and buy again cycle.
And I still hope people share how it looks on theirs, I have not seen any talk about this matter before.

oh
but you still will not know what you will be getting, if you re order
it;s kind of a long shot that more than 1 or 2 people on here will have these exact pliers

Any size in this series is good info for me like I have said before, I may want to order other sizes too, in fact that is what I wanted.
These series of pliers are quite popular, not sure why you imagine only 1 or 2 people having them.

The V jaw type are so much better at everything. If you’re worried about scratching things, put some electrical tape around the V jaws before you attack anything that you might scratch. Or like I said, make it smooth yourself. If you don’t have tools to do it probably know somebody that does. And they will tell you to get the v jaws.

Like Oli said, if you don’t want to scratch something, you’ll have to use a barrier, like paper or tape or whatever. This would be the case even if both surfaces were ground.

Total noob here and first time posting but I do own a set of 86 03 250 (same size without the comfort grip handles) Knipex pliers wrenches. I don’t know if it’s clear in the attached pictures but the upper jaw is forged with a machined surface. If it didn’t get machined, there would be a parting line through the gripping portion of the upper jaw. However the lower jaw doesn’t have any obvious secondary operations. My thoughts are that it is investment cast. Either way it’s not as rough as the lower jaw in the set you received.

i have ~10 knipex PWs, and the surface finish on the jaws of OP's pics are within the range of what i've seen. it's normal imo, but funny to see both on one tool.

besides, after use, they will get a bit chewed up and will have bigger surface defects than that.

 

btw, i would have asked this on garage journal.

Checked my set of pliers wrenches, they all look like strangequark’s one.

It looks like neither the top nor the bottom pieces are forged as you can see the parting line of the pressure casting mold and the taper or draft in the side wall of those “strengthening” holes in the lower jaw. Likely the flashing was unsightly and needed to be ground off the top jaw.

Odd, mine is also 86 03 180, but both top and bottom are the same. Both sides are not quite ground but not rough.

I see that faint seam there in the middle along side the length of the jaw.
That is what was so raised on the first Knipex I have bought that was only clamping with the seam, the not whole plain of the jaw.
Interesting the process is not the same on all these lower jaws, some have the seam some only have some rough “casting” surface?
