Greetings,
viewers, welcome back to the channel.
[1]
In today's video,
we're going to be taking a
[3]
look at some one off, prototype,
Ko-ken tools.
[7]
So let's get into it.
[19]
So some of you may be thinking right now
off hand.
[22]
Wait a minute,
what are you talking about, Mr.
[24]
Subaru? One off prototypes?
[26]
You've got the same tools over here
and over here.
[30]
What gives?
[31]
So this is my Z-series, 36
tooth, 1/4" drive ratchet.
[36]
And this is a 1/4" drive, metric,
nut grip socket set.
[42]
But what we have
here is a prototype of the SAE 1/4"
[46]
drive socket set, which has been available
now for about a month.
[51]
These were a special run
[53]
from Ko-ken Japan,in response to a Tik
[57]
Tok video
I did, and a short I did, here on YouTube.
[61]
People wanting SAE sizes of the nut
grip socket so Japan fulfilled that order.
[67]
They made a quantity of 200 and Ko-ken USA
is in the process of selling those now.
[72]
So if you want to get that set of SAE
nut grips,
[75]
the link will be in the description below.
[77]
Then off here to the right,
we've got two prototypes
[80]
of the new 72T 1/4" drive and 3/8"
[85]
drive compact Z Series Ratchet.
[89]
Finally, the 72T version of the 1/4"
[92]
is right on the horizon.
[95]
We got the 72T version of the 3/8"
Z series
[98]
ratchet at the beginning of this year.
[101]
Again, four years of research
and development went into that ratchet,
[105]
and they improved
all metrics of that ratchet.
[109]
One, keeping overall size the exact same.
[111]
They didn't add any bolt to the ratchet
to go from 36 to 72 teeth.
[116]
They actually increased
the strength of the mechanism
[119]
by going to the fine tooth over the 36T,
[123]
and they lessened the already minut back
drag of the Ko-ken Z series ratchet.
[129]
We've talked about this before how smooth,
how wonderful,
[132]
how light
the movement is on the Z series stuff.
[135]
Well, they have a lessened it with the 72T
1/4" as they did with the 72T 3/8".
[141]
No official date is available yet
on when these will be for sale,
[146]
but expect them within the next month
or so
[150]
or beginning of 2022.
[152]
Seems they are very close
to getting this production ready
[156]
and getting it manufactured
and shipped out to retailers.
[159]
So starting off, we're going to take
a better look at the SAE nut grip sockets.
[164]
Part number for this SAE nut grip
socket set
[167]
is RS2450AS/5.
[172]
If you look it up on Ko-kenUSA.com
don't put the forward slash five.
[176]
It's not in the part number there.
[178]
I will put the link in the description
again for the socket set.
[181]
For those of you interested
so you can find it easier.
[184]
So Ko-ken's patented nut grip technology,
we've talked about it before
[188]
in previous videos,
they have detent balls on opposing flats
[193]
with a spring around
outside to hold tension on them.
[196]
Now what that does
is it holds the head of your bolt,
[199]
your nuts, etc; any fastener in place.
[203]
Say if you need to start in a blind hole,
or if you need to start down
[207]
in a cavity
where you can't start with your fingers
[210]
or drop it in place with your fingers,
you can stick it in the socket.
[214]
It will hold it in place
and you can guide it in with the socket,
[217]
extension, ratchet, etc.
[219]
to start that fastener.
[221]
Now, a lot of people might be thinking,
Well, there's magnetic sockets.
[224]
Why would I not get a magnetic socket
instead of a Ko-ken nut grip socket?
[229]
Well, the big advantage to a Ko-ken nut
grip socket is it works on any material.
[234]
It does not have to be ferrous
metal like a magnet.
[237]
So aluminum fasteners,
stainless fasteners, plastic, etc.
[242]
the nut grip socket
will grab a hold of it,
[244]
regardless of the material
it's made out of.
[247]
Another advantage is with magnetic sockets
over time and use
[251]
they get metal shavings,
black sand build up on the magnet
[255]
it gets in the socket it creates.
[258]
You know, it
[258]
lessens the ability of the magnetic force
from the socket
[262]
and also just makes it cruddy in there
where you can't
[264]
get your socket on your fastener
very effectively .
[268]
So that's why
these are such a great product from Ko-ken
[271]
Japan,
way more useful than magnetic sockets.
[276]
Again, they've always made these in
metric sizes, but you guys viewers wanted
[281]
SAE. Guys that work on motorcycles,
Harley-Davidson, guys
[286]
that are in aviation, other industries
still using SAE sizes.
[290]
Now you have the option
the ability to get these nut grip
[294]
sockets, in SAE size 1/4" drive.
[298]
If they are popular enough,
they might start offering
[301]
1/2" inch and 3/8" drive sizes as well.
[304]
So if you want to show your support,
show your interest in these tools,
[310]
you know the best way to do that
is by purchasing a set.
[313]
Purchasing a set of these
will entice Ko-ken to look into furthering
[318]
their SAE sizes, for these sockets,
and others that they produce.
[323]
So again, let them know what you think.
[326]
A lot of you emailed
a lot of you DMed them on Instagram
[329]
when we had the poll up
asking about these sockets.
[332]
But the best way to let them know
at the end of the day is
[334]
if you're a wallet, vote with your money.
[336]
Show them the support for creating this
and encourage them to create more.
[341]
So moving on our next
item is the new prototype
[344]
72 tooth 1/4" drive
ratchet and compact 3/8" inch ratchet.
[350]
We're going to take them off
these placards
[351]
and take a look at them and compare
and contrast them to the old 36
[355]
tooth mechanism.
[357]
So here we've got the 72 tooth prototypes
versus the old 36 production models.
[362]
As you can see,
[363]
they're basically indistinguishable
other than the laser
[366]
etching on the face plate, saying 72 T
and no part
[371]
no or Ko-ken engraved
or stamped in the handle on them.
[376]
So as with the 3/8" drive version,
they have basically taken that 72
[381]
tooth mechanism and shrank it down
for the quarter inch drive body.
[386]
The two piece
floating/sliding pawl system is exactly
[391]
the same just shrank down for quarter
inch drives size
[395]
and for the compact
three eighths in quarter body.
[399]
So the original 36 tooth Ko-ken Z-series
quarter inch ratchet, the standard length
[404]
the 2725 z has become my favorite quarter
inch ratchet
[411]
due to the size, the compactness of it
[414]
and that extremely low back
drag on the mechanism.
[418]
The fact that it's 36T has not hindered me
one bit in using it.
[423]
I haven't had to run, grab
say a snap on 72,
[427]
or my Hazet 90T HiPer ratchet
or any of my higher tip count ratchets
[433]
It's I've not been in a situation
where this hasn't got the job done.
[438]
That said, upgrading to a 72T
[441]
mechanism is a welcome addition
because again,
[446]
no change in our dimension
[448]
improving the strength of the drive
and lessening the back drag.
[453]
So a win win all the way around.
[455]
Let's go ahead and take the face plate off
of both of these ratchets
[458]
and take a look at the internals
of the 72 and 36 and compare them.
[493]
All right, now
[494]
that the face plates off,
we can see the old 36
[497]
tooth here on the left
and the prototype 72 on the right.
[501]
I'd love to show you
these in use in action,
[504]
but with the size of them, it's
extremely hard to do.
[507]
Going to try to put clips in
if I can get that to work,
[510]
if I can get it to show up
well enough on camera.
[513]
As I said earlier,
they basically shrank down the 72 tooth
[517]
that they put in the full sized
three eights ratchet
[520]
and put it in the quarter, same
two piece pawl system, sliding pawl system
[525]
and the same 36 single tooth
[529]
and the old ratchet.
[549]
Here's a quick, unscientific test,
[551]
a little demo showing the 36 versus
the 72.
[556]
Click for click
with this little thumb spinner.
[580]
Really quickly.
[581]
Size comparison between the Ko-ken
Z Series 72T
[585]
and a T72 Snap-on.
[588]
Versus an 88T Matco 1/4" ratchet,
[592]
and versus a 90T MAC AXIS ratchet.
[596]
The Ko-ken is far more compact
than the big three from the tool trucks.
[601]
All right, guys.
[602]
And there you have it your quick
look at a brand new Ko-ken product
[605]
and two prototypes soon to hit the market.
[609]
Thank you so much for watching.
[611]
Hope you enjoyed the video!
[612]
I'll see you in the next one.
