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

Z-EALとか無かった頃に買ったラチェットだって滑らかで軽快
ジール以外にも滑らかで軽快なラチェットは有りますよねー。
もし良かったら、ご愛用のラチェットについて教えていただければ嬉しいです。よろしくお願いします。

kokenの3753Jと、同じくkokenの首振りショートラチェット（型番不明）、30年程前に多数の工具と使い比べて選択したお気に入りでいまでも現役。
ググってみたら3753Jはまだ売ってる、すごい！
コーケンさんの3753シリーズはとても滑らかで良いラチェットですよね〜
長年使い続けている方がいる！
まさに名機の証明だと思います。
このサイズにハチブ付いてるの重宝してます
コメントありがとうございます。
このサイズにハチブ付いてると便利ですよね～
自分はクイックで変換して使っていますが
専用はやっぱり良いですね
@@mono-story 贅沢を言えばシブイチと両方欲しいですよね。
中にはトルクを掛けたくないのも有るのでｗ
27系は名器になると思います。
全く同感です。

Great video. Looks and sounds like a great ratchet. The extra length must be very useful. I was deciding on whether to replace my old SK (US manufacturer, not SK11) model 40970 1/4 ratchet with either the Koken Z-EAL 2725Z ratchet or the Snap-on model T72 1/4 ratchet. The Koken was the stronger candidate, but I was concerned by several reviews I had read about problems with selector switch changing position accidentally or the switch failing. Have you experienced any issues with the selector switch? Nice comparison of the standard verses the Z-EAL sockets..I really love the Z-EAL sockets, they come in handy for tight spaces and the quality is excellent; I have 3/8 and 1/2 sets, but not yet a 1/4 set.
Thank you for your comment.
I like the 160mm length.
The T72 is by far the best 1/4 ratchet, but it's very expensive.
In that respect, the Z-EAL 2725Z is affordable.
If you like the Z-EAL system,
I think the 2725Z will be a very satisfying choice.
I introduced it in the video,
If the selector is difficult to move,
This is often caused by over-tightening the Torx Plus screw that holds the back cover in place.
Most cases can be resolved by adjusting the Torx Plus screws.
Personally, I am thinking of fixing it with a screw lock etc. after adjustment.
Z-EAL's 1/4 socket is surprisingly small and has a unique presence.
please refer.
@@mono-story Thanks for the tip on adjusting the torx screw - sorry, I saw that part but since there is no caption translation available for the onscreen text, sometimes I’m not sure as to the intended meaning. Thanks also for the recommendation of the Z-EAL 1/4 sockets; I’m watching the price of the Z-EAL P2285Z 1/4 socket set, and when the it drops low enough I’ll order it. I’ll keep you posted on that purchase.

ネジロック(ロックタイト)必須かもです
使用中いきなり分解してギアが行方不明になりました
それでも使い勝手が素晴らしいので再購入しましたけどｗ
全く同意見です。
裏蓋がゆるくなったのも有ると思いますが、
一本ネジの構造がそろそろ限界なのかもしれません。
次に出るラチェットはおそらく全面的なリニューアルになると思います。
Very good 😊😊😊😊😊😊
Thank you for your comment.
Ko-ken 2725Z is a great ratchet wrench.
パウルギアの向きが表裏逆に見えますが、目的があるのでしょうか？
コメントありがとうございます。
パウルギアの向きなのですが、新品でこの向きでした。
自分も最初違和感があったのですが、
一段目は切り替えノブを抑える出っ張りがあっれで逆向きにできません。
二段目は逆幹にするとギアの咬み合わせが少しズレてしまいます。
ボディーとの摩擦を考えると、逆向きの方が良い用にも感じますが、
皆さんに紹介する映像は新品状態がわかるものは新品状態を優先しています。
個人的には3/8も1/4もこの向きに方が若干ですがスムーズに感じているので普段使用する際もこの向きにしています。
参考にしてください。
@@mono-story 返信ありがとうございます。
丁寧な説明ありがとうございます、自分もギアの向きを変えてみたりしようと思います。
Hi, I have every 72gear Zeal ratchets from 1/4 to 1/2 and have been disassembled all of them when they arrive. All the dog gears have the smooth side facing the plate. Just for your information 😊
Thank you for your comment.
Thank you for sharing this valuable information.
