I have several 1/2" drive sockets which have the hole. All of them from '70s or '80s. I think its for the detent ball. There are no dents inside on each side for the ball, only the one hole on one side. So you must insert the socket always oriented the same. Hmmm... maybe it there to allow access to the ball if it gets stuck? You take a punch and strike it to release the ball?
Ps. I think all my impact sockets also have the hole (?).
The hole is there for industrial type drives that have a cylindrical pin rather than a ball detent. This is so the socket can't fall off. It has to be released by depressing the pin with a punch.

i dunno...i guess the german tool experten already have enough Stahlwille, Gedore and Hazet tools.... ?Talking of Elora how come they never get much of a mention on this forum by German tool experten ? They are a traditional family owned business making a wide range of tools in Germany. In the UK they are distributed by Draper, one of the largest tool importers, so they must have significant sales.
Tools..

Typical new age Snap-on Corporate silliness.
No COO stamping on either the driver or packaging.

Well, well, finally some proper tools
I also have Kuka robots and Fronius CMT Robacta in my "toolbox" along with some other goodies .
Unfortunately my employer doesn't allow me to take/divulge pictures of the equipment or tools.
The "tools" you have there looks brand new/unused, you work for a line assembler/integrator?

both german made ?Having broken another plastic handled junior hacksaw and inspired by the recent best hacksaw frame thread I went looking for something a little different:
Thickness, comfort, ratcheting action..... There are lots of ways to compare them. And most are a lot more practical than tooth count.Not sure how you can compare the two considering the Nepros has about triple the tooth count.
What do you think of the Hazet fine tooth ratchet ? Someone here posted this picture a while back. The head seems a bit more bulky in design than it could be...
Greetings from California! Yes, I work with mostly Kuka robots (occasionally Fanuc and ABB), Fronius CMT welders, Böllhoff self-piercing riveting systems, etc.
Although, I am not allowed to take/divulge pictures of my work either, similar to you. Can you tell that the robots are uncharacteristically, red?
That line pictured was brand new, yes. The facility I perform most of my work at has a maintenance system in-house. They like to maintain their own assembly line systems, which is fine by me. This means I usually get to play with strictly brand new toys all the time!
My company engineers, configures, installs, and supports robotic assembly line and special tooling systems for both automotive and small (electronic, pharmaceutical, surgical) scale industries around the world.

Hi, GTI!
Darn, i didn't expected been busted so quickly!��
Work there also?
It's interesting to see how the Nepros compares to the Koken Zeal
Actually the koken zeal doesn't use a system of two Springs. It's very unlike other koken ratchets, its basically a single pawl and then the gear!Now that I see the inside of the Nepros I wonder how much torque can it handle with that many fine little teeth? I do like the clean mechanism, it looks robust vs. the Koken with 2 springs but I don't have either and can not comment hence the need for information.
Thanks for raising the question and posting photos of the guts![]()

The fine tooth ratchets are typically stronger than older coarse tooth ratchets since more of the teeth are engaged and the torque load is spread over a larger area. I primarily use my long handled 3/8" Nepros ratchet and I have not had a problem when applying a lot of torque. I also use my long handle Snapon ratchets with lots of torque and have had no failures. Of course it is possible to damage any tool if not used properly. If you need tremendous torque then the breaker bar or something similar is the proper tool, not a ratchet.
The Nepros 3/8th can handle more than 300Nm before the drive square shears according to a Japanese magazine test.
Looks awesome! [emoji106] [emoji106] wish I owned a pair and will probably be picking one up soon!Here are pictures of my first Wiha pliers purchase. It is Swiss made too! Great attention has been made to assure that there is no jaw gap when the cutters are in the closed position.
Wow, That's impressive!! That's good to know. Now that I have received all this great feedback, who has the best price for Nepros products especially a 3/8 drive 90 tooth ratchet?
Always learning something new!
