Ko-ken Z-EAL 2725Z-160(G72) 1/4"SQ

Smooth and light

Koken 1/4 72 gear
rotates smoothly
Koken did a great job!
No feeling of metal rubbing together

Structurally it is the same as 3/8 72 gear.
I feel more accurate
to give strength
I heard that it took a lot of effort.
When changing to multiple gears
to give strength
I think there are several options

make the head bigger or thicker
When many manufacturers make multiple gears,
By making your head bigger
increase the diameter of the gear
increase the thickness
By increasing the contact area of gears
increases strength

Koken
(Torx Plus 6IP)
"Without changing the size and thickness of the head"
“I want to increase strength with multiple gears.”
After trial and error...Improved accuracy
I imagine that I have arrived
By increasing accuracy
Greater adhesion
Same as head size
to increase strength
I think it was successful
as a result
smoother and quieter
Gears are securely engaged
Due to the good system of Z-EAL,
Comfortable to use with little play
Small head with multiple gears
Great for small spaces
To the highest level ratchet
I think it's finished

Z-EAL joints
Adopts special shaped dimples
Comfortable with very little play
Standard model and other companies' products
Even in combination
I've tried all the products I have and
I was able to use it without any problems.
(It seems that some products may be locked.
If anything, I get the impression that the locking mechanism is more compatible.)
The fit between the gels is great
I think it's best to have Zeal with Zeal.

Z-EAL socket
In-depth performance
Z-EAL
Standard
Super short and thin
deep or semi-deep
on the premise of aligning
This is a recommended socket.

With a budget not much different from KTC and TONE.
More pointy sockets available
Although it is a little difficult to obtain
Recently, it has become easier to obtain through mail order.

By aligning Z-EAL with Z-EAL
You can feel the goodness even more

If you are having trouble choosing a tool
Arranging with Zeal
It might be a good idea to include it as an option.

Zeal doesn't have wobble.
Standard series wobble is excellent
Use of a larger ball for wobble
relatively long structure
Easy to get the angle
If you insert it all the way
It can be firmly fixed
I use it regularly

Let's think about why there is no wobble in Zeal.
Wobble attached to 1/4 Zeal 14mm
If you insert it all the way, it will stick out.
Barely standard bolt
Clearance is secured
Is it difficult to wobble for thin sockets?
I'm imagining something like that
Personally, I like the design that takes it to the limit.
I absolutely love it
When you actually use it
Almost no problems with bolts
Regarding nuts...
I decided to switch to almost deep (lol)
There are times when I say, “This guy won’t do it.”
There are some things that "it has to be this guy"
He is a good partner who has helped me many times.
8mm won't go all the way in (lol)
But you can use it without any problem.

Z-EAL 2725Z-160(G72) 1/4"SQ precautions
The screw (torx plus 6ip) that holds the back cover is
Even when new
loose or hard
There seems to be a product that does
If you tighten this screw too much, it won't turn.
You will not be able to switch
It is necessary to tighten it to a suitable level of firmness.
It became more severe with 72 gears.
Secure with screw lock etc.
I think it's necessary
