SK 3/8 90T v Snap On F80

Saw the SK 90T ratchet was for sale at HJE ($66 shipped to me), so I had to grab one to see how I would like it. Taken a long time for this ratchet to get to market, so my expectations were high.

To start, the length is 8" and the chrome is great. The handle is comfortable, and will work for a wide variety of hand sizes (bigger hands can place their middle finger below where SK 80200 is stamped and their thumb and pointer finger above, smaller hands can just place the thumb and pointer below where the stamping is). I could wish for a thicker handle, but then again, I would probably only be happy with a 1" diameter handle on all of my ratchets, so that may just be me.

Here are a few dimensions (in MM) with Blue highlighting the best in each category. It is fairly compact, but the difference, as I've said previously when comparing the Matco/Armstrong 88T to the F80, is not a deal breaker. They're all actually much closer than you would think by looking at them.

Several who had handled the prototypes in the past had mentioned that they felt rather heavy. Both the F80 and SK 90T come in at the same 10.5 Oz., so not bad for either in my opinion. The SK, with a smaller head, feels better balanced, as opposed to the head-heavy Snap On.

The ratcheting mechanism is fantastic. The mechanism is light, crisp, and smooth. The back drag on it is significantly lower than the equivalent F80 from Snap On. It just is REALLY lower than the F80. The F80 has never been the lightest back drag ratchet, but it's never been bad either, so how light the SK is is great work. Slop is nonexistent and the next tooth feels like it engages right away with no slack. Great job here.

It may look like an Apex single pawl design, but there are several features that set it apart. The selector (anodized aluminum?), on the left side, has a tab that slides along a "shelf" specifically milled out for it. This limits the travel of the selector switch. Nice feature.

There also are two recessed areas on the bottom part of the head behind the pawl that allow the ball/spring to sit firmly in them (just below where the shelf for the pawl tab slides on). This results in a solid and positive click/lock into place when changing directions. Again, something that the very similar Apex/Matco design lacks.

It also has a large raised circle in the middle that fits into a recessed circle of the gear/drive piece. My guess is that this helps reduce the gear from moving around, jamming, and such. It also means the gear isn't being pushed away from the pawl under load, making it a stronger ratchet. Take most ratchets, put a 12" extension on them, pull down on the extension, and try ratcheting it. Many will not ratchet like this, some do but feel horrible and you can tell the gear/pawl are being pushed out of place. The SK does this with ease. The F80 is okay, but not fantastic, at this task, speaking to how well machined and how precisely everything fits up in it.

The pawl is large, with 14 teeth engaged (Snap On is 7 IIRC). Well made, and the entire thing engages with the gear, not just half of it like some other single pawl competitors.

As far as things I don't like about it is that it doesn't have O-rings around the drive anvil like Snap On and Matco have. The opening in the cover plate is tightly machined (significantly less gap between cover plate and anvil than the Snap On), but I'd like an O-ring there regardless. I also don't like that they used Hex screws instead of Torx screws (it's a 2MM or 5/64, which ever one fits in there better for you :p). Both super minor complaints....

All together, this is an excellent ratchet. Having used it next to my Snap On F80, I very much like the SK 80200 WAY better. Better balance, slimmer, longer, better ratcheting mechanism, and cheaper. It took a long time to come out, but it's a great design. Unless it proves to be weak or problem prone over the long haul, it is a better ratchet than the F80. With a used F80 being around the same price (and having technically no warranty from Snap On if you buy it used), I think the SK 80200 is a better bet for most people.

Hopefully the 1/2 and 1/4 drive versions are just as good, but the SK 90T 1/2 drive will have a much harder time against the Snap On S80A, which is just a fantastic 1/2 drive ratchet.

Is the cover plate on the SK flush with the ratchet body or does it sit ever so slightly proud?

The SO will be perfectly flush.

Sounds like a winner.

They'd really have a winner if they made a locking flex head version with a lock that's as good or better than the Armstrong/Matco.

Flush. The Screws are also recessed on the SK, whereas they just ever so slightly stick out on the Snap On.

If they can come out with a good locking flex, I'll be all over it. I have the 1/4" drive armstrong/Matco locking flex and truly believe that is the best locking flex design I've ever seen.

If you like Snap On better, i can cut the handle shorter, put a cheap ugly lever on it and make some of the parts overseas.

It will still have more teeth and cost half as much.

I like Snap On too, but, try ordering one from Amazon.

Thanks for the review! That's a sweet looking ratchet.

thanks for the excellent pictures and commentary. I like the SK too , looks sweet! I'm not alone about the green touch or the lack of knurling.

That maybe a side effect. My guess this has more to do how the torque is transferred to handle, due the thinner wall construction. Perhaps your inside industry contacts can help us find out more.

P.S. interesting that you declared a winner on 0.01 mm margin for a calculated number from 3 measurements. The key dimension that people need for a low profile design is from the outside end of the head (or selector if it matters, it might not) to the end of a socket. The end of the anvil isn't the same as where the captive retention ball engages a socket.
more SI units
SK 3/8 = 9.5 mm
10.5 oz. = 300 g

Correct on all points, and I put all the numbers up there so people could make their own decisions. In all honesty, even the few mm between the Armstrong and Snap On make little practical difference in my experience (either they both fit or they both don't fit). With production tolerances, it wouldn't surprise me if the Armstrong/Matco and SK switch spots depending on who got which one on which side of the target size.

I considered measuring with a socket for all of them, but ended up deciding against it. Different ratchets hold different sockets differently (both in terms of height and how much slop there is), which introduces more variables. For example, the SK ratchet pictured above, when combined with a Mac 20MM 3/8 drive socket, there was almost no slop (up and down). When that same Mac socket was on the Snap On, there was more slop. However, when I took a Snap On 19MM socket on the F80, there was no slop. With the difference in socket heights between manufacturers, I instead decided to just do anvil height. The ball detents all are roughly an equivalent distance down from the top of the anvil in each case, so total anvil height should be a fair enough approximation for most of us. And again, even the few mm difference is mostly irrelevant. Jumping down to a passthrough ratchet or Snap On low profile ratchet and sockets will be more useful than switching to a slimmer full size ratchet IME.

I like the way the cover plate sits flush, but what I don't like is the grooves cut into the handle; they're sharp and cut into my finger when I squeeze the handle. The new SK is groove-less which is a huge plus for me.

Bingo
Too bad there is no easy metric for how well ratchets hold sockets, or the back drag for that matter.

Back drag can be measured fairly easily with the right gauge. I found my SK round head 1/4" drive averaged 1.4 oz-in and my 1/4" drive Armstrong 88 tooth locking flex was very close at 1.3 oz-in. Unfortunately I don't have torque watches with the range needed for 3/8" and 1/2" drive ratchets.

I have used this ratchet at work daily since I got is as one of the first to get one and it is a really great ratchet, the feel and balance and over all design of the ratchet is just excellent
and would recommend it to anybody.

Loscaldazar,

Is there a hole on the back side of the pawl for the spring to go into?

Your pictures show the teeth side of the pawl.

I hope SK comes out with more ratchet configurations soon, because their new ratchets look really nice. If they have good strong flex joints on the flex models, I will probably sell off several of my 3/8" drive Snap-on dual 80 ratchets and replace them with SK.

That's where I'm at with it. I'll sell off all my bare handled Snap-ons and replace them with the SK equivalents when they're available with a knurled handle.

Loscaldazar,

Your pictures show the teeth side of the pawl.

If you look at the photo with just the cover plate off (first photo after the spreadsheet chart), you can see a wide "U"-groove machined into the back of the pawl. That is all there is. When you turn the reversing lever, the spring loaded metal cone (the gray piece behind the pawl) flips to the other side of the "U." So no hole, the metal cone just sits back in that U groove. The spring certainly won't be able to jump outside of the pawl.

Additionally, the spring is only used to keep the pawl in place when the mechanism is ratcheting. When it is locked (e.g. apply force to remove/install a bolt), the drive gear forces the pawl into the wall of the ratchet to provide the locking force.

I also like how the hole in the bottom of the SK gear (along with the cover plate) carries the applied loading forces instead of it being carried by the gear teeth pressing against the ratchet head's inner wall like most other ratchets. Hopefully some customer testing will be able to prove that the hole in the back of the ratchet gear doesn't weaken the square drive at all and increase the chance of the square drive twisting off during heavy use.

The hole doesn't go all the way through to the anvil (I'd say about half way through the gear, stopping short of the anvil but I might have to double check that), so it shouldn't have much of an effect, if any, on the strength of the anvil.

Of course, as I've said a few times already, time will be the best indicator of strength.

Am I the only one that can't see the OP's pics anymore? I could see them yesterday. They no longer show up in any browser for me. I see this...

Photobucket updated their terms/conditions two days ago, and now they have been going through account after account and removing ALL 3rd party linked pictures unless you pay them to now do something they previously did for free. I'm working on moving them all to imugr and re-uploading them.

Photobucket is making it difficult with their crappy website and constant pop up ads and the fact that their download album feature only works 1 out of 5 times. Photobucket used to be okay, but the last few years they have quickly declined and this is the last straw for me.

IIRC imugr doesn't play well with GJ. You may be bailing your boat with a bucket with holes in it.
It's better if you load the pictures directly to the site from your computer/device.

Yeah, just tested a photo from imagur and it didn't work. This website won't let me upload anything to original post (keeps saying my security token is invalid). Works fine on this post, so that is where they are going right now!

Edit: Got all of them but one in the original post (keep getting same error message). That'll have to do until I figure out what to do after work.

So does anyone know if the Knurled handle version that was pictured in another thread is actually going to be offered in the future or was that just a prototype?

This is a great designed ratctchet and well made, as I posted earlier this along with the 1930 design pro series ratchet should put any talk to rest about the SK Tools ratchet comments from people. I like both designs a lot and this new one puts away a lot of people's complaints about the round head pro ratchet design and adds a great new design that is well made and should be around maybe even as long as the SK round head ratchet

God I can't wait to try one I have close to 100 pro brand ratchets and I love my so tuff1 rats they are very well made and I agree the dual80s are not the best in the bank drag category it gets worse with 1/4 and better with 1/4 but I have found that you can try 2 3/8 for example and both be different. I'm waiting for 1/4 as its my favorite size but it's killing me to not buy the 3/8 but I want a long handle atleast. I think the tuff1 rats are the smoothest around with a broke in one with next to no back drag can't wait to try the 90t. I own the 18" flex and long non flex 3/8 Mac Axis' and they are my second choice and im also very impressed with the new AJ manufactured Matco ractchet i have a couple i got from warranting which took months to get but was worth the wait. The dual 80 is last on my list of truck rats Even the Cornwell I like more just my preference not saying it's a bad rat just nothing amazing.

great info. i have said it time and time again. i have a really nice 3/8 drive dual 80 with a fabulous red hard handle. it is a drawer queen covered in dust. other than being some tasty kool-aid i have never seen much to write home about a dual 80. i much prefer my sk roundheads, proto big dawgs and armstrong/gearwrench 60/88 click ratchets.

i will be getting one of these new sk ratchets very soon.

After my Armstrong 88T walked away, I'm going to give this one a shot. I really liked the Armstrong, too.

I have a couple dual 80s (long handle and flex) and like them but I need a regular length handled ratchet. I'm looking forward to grabbing one of these SKs.

Is SK going to continue making the round heads?

I hope so. While there are tons in circulation, I tend to buy ratchets new unless the price is ridiculously cheap (like a pawn shop that doesn't know the brand or flea market) and every SK ratchet I've purchased has been new. My most commonly used ratchet is their 3/8" drive round head flex ratchet. I use it every day at the garage. There are a few ratchets that just feel indestructible. SK's round heads make the grade. I'm a big fan; I just enjoy using them.

The great thing about these new ratchets is they're fine tooth, low-profile and I'd buy one if I didn't already have an F80 (it'd be a redundant purchase); one ratchet really can't handle everything and the round heads do have some shortcomings. Nevertheless, SK really covered their bases with this ratchet in conjunction WITH the round heads. Keep it made in the USA and keep the round heads alive! Great job, SK.

To answer a couple of questions above: yes we will continue to make the round head, as well as a dual-pawl insert for round heads for a narrower arc-swing, and yes, we will be rolling out other configurations, including flex head models. There is talk internally of making a knurled example, but that's not confirmed.
