NICE! I'm envious of you guys' purchases.

^^ Pretty new to GJ, but mayyn! I knew someone was gonna beat me to it. Ricleh you always get that exclusive stuff first. Well I just also picked up my ratchet today. Just like what he said, the quality is what Nepros always delivers... none can compare! Really low resistance. I can't compare it to a SO ratchet atm because I forgot how they feel. But I did use a classmates Matco ratchet. Its way smoother than his.
I did get the new master set a while back. The box is really good quality but i cant really compare it to anything because Nepros was my first, professional tool company, I ever invested in.

What a good choice you've made in choosing KTC/Nepros :) What do your classmates have to say about Nepros tools?

Was the Matco ratchet you compared with the newer 88-tooth model?


Ricleh,

Can you please take a group shot with an SO Dual 80, Ko-ken Zeal, and a Matco 88 (assuming you have one)?

Thanks, really feel welcomed... atleast to the thread lol. And yes the Matco ratchet was their 88 tooth.

I think I might have been the last one. I asked him really late and told me that there was only 2 left available and I still waited on it.

Here is a shot of the SO Dual 80, Nepros 90 tooth and the Ko-ken Zeal

Ricleh,

BTW, thanks for the photos. :thumbup:




....

Two pages back, I mentioned that the strength remains the same as their 32-tooth model. For reference, independent testing showed a standard NBR3 will shear off its square anvil at 250ft/lbs of torque.

Did that independant test have any other ratchets included? So the square drive broke before the teeth?

IIRC, yes, the drive end broke before the internals did, which surprised the testers. They also tested a Deen (Taiwan), KTC 21c version, and a Snap-on (batman pawled 36-tooth). I'll try to scan the test results and post them.


JK,

I scanned the magazine and finally uploaded it:

*note: don't fall into thinking that tools should be chosen based solely on these numbers that simply show what is the "strongest/hardest" or "weekest/softest".

Just because brand "X" resulted in the highest value, it does NOT neccessarily equate to being the "best" of the bunch.
The results are not indicative of the entire brand's quality.
There are many other factors involved in choosing a good tool that suits your purpose, needs, and taste.
:)

The first picture of the ratchet test was a comparison between four standard length 3/8" drive ratchets. Four of them are batman pawls, and the round head is a Facom type.

They all produced similar numbers, with the Snap-on posting the highest number. The square anvil broke off on all four of them; the gears were fine.

The second photo shows a test on 3/8" drive (in a 1/4" drive body).
The round head, Facom style was the clear winner. In this test, the square anvil survived; the gears/pawls did not.

what does "peak" and "break" mean ? why there is sometimes a huge difference between "peak" and "break" and sometimes not ?

I was also confused by that, and never figured it out.
I doesn't make much sense does it, when one is close to eachother and another is way different. :headscrat:
It's not explained in the text anywhere.

So they stuck a 3/8" drive in a Facom 1/4" ratchet? If so I know what I might be trying this week :)

Hrmm, if you're asking that question it makes me wonder if there was/is such an animal offered by Facom? I was assuming that they offered it .... as that's what the magazine said they tested this time :headscrat

A little hybrid might be born this weekend in your lab? :D

No such animal exists as far as I'm aware -doesn't show up in their catalogue either. The offer a stubby J-series (3/8") ratchet with an all-metal handle, and presumably the same sized head as the other J-series.

The one in the article looks like it's stamped R.161 which is just the standard 1/4" round-head (body anyhow).

The way the Facom is made, I would say it's impossible to do that. The outer ring for the pawl is the housing itself (if that makes any sence?).

Must be some kind of typo/mistake.

Yes, there is. Here's one more for today :)


They are from the 2007 Factory Gear Magazine.

I'm curious which direction they loaded those. I've broken crescent wrenches using them backwards a few times, but I've never managed to break one using it correctly. Always broken them by spreading the jaws apart.

The Nepros adjustable wrench has a directional arrow forged into it so that users are reminded of the proper use. Other brands like Proto and Snap-on once used to do that as well.

As for the break test, the weakest link, regardless of the direction it was placed on the test stand, is still the floating jaw and the worm gear.

Althought the Bahco adjustables scored the lowest, it's still above the DIN standards that it's supposed to conform to. The DIN standard calls for 3265 kg-cm (236 ft-lb) minimum. The Bahcos are above those numbers, and not only that, they sell replacements parts if you were to ever break one. The minimum required by JIS is 4700 kg-cm (340 ft-lb) and for ANSI it's 5204 kg-cm (376 ft-lb).

The X-axis looks like seconds, but there appears to be a pretty wide range on the scales there. That might imply that the force was applied at different rates. Do they address that at all in the text?

Yup, x-axis is seconds.

I think it's proportionate with the break points. I say that because if you look at the 8 second mark, they are all at or slightly above the 7500 kg-cm mark, with the exception of the Bahco 9072.

Wow, cudos! I bid you my humble apologies and exit now silently. :D

I would never had thought they used the same size internals, but it does make some sence once you start to think about it.

Here :) :

The plier test was used to find out how much pressure it takes to cut through a 1.6mm piano wire. The cuts were all made 8.8mm away from the rivet/pin. Keep in mind that all pliers retained their handle grips. Also keep in mind that the test apparatus places the pressure at a predetermined length from the pivot point. Therefore, the numbers given are not reflective of the actual pressure since handle lengths can vary.

In a plier test, there's definitely a "feel" that cannot be measurable. Although KTC posted the highest pressure required, the actual feel that gets transferred to the operator's hand didn't correlate with those numbers. In other words, the KTC actually has a feeling of better cutting performance than what the number says.

After the testing, the Knipex and Deen (Taiwan) showed little wear on the cutting edges. They should prove to be durable. The Bahco, although posting the lowest number, resulted in dulled cutting edges.

In choosing cutting pliers, these numbers are not as important as actually operating them in your own hands and experiencing the cutting feel that transmits through the handles. This feel cannot be measurable by any test, except through your own hands.

I was curious about the nepros 90 tooth ratchet and decided to contact nepros.

My initial inquiry:

Greetings, I was wondering do you guys have a catalogue whether it be online or hard copy? also, in regards to the nepros 90 tooth ratchet, will more variations of the 90 tooth ratchet be able in the future such as flex, longer, 1/4, or 1/2 models? Thank you

Response:



Thank you for your email.

We do not have English Nepros Catalogue, but in Japanese, we have.

Please go to address below.

http://ktc.jp/catalog/index_category.html#index_nep



Other types of 90-tooth ratchet are under development.

I am not sure about 1/4 and 1/2, but 3/8 flex and longer will released in the near future.



Best Regards,
