This Genius seems a good idea for more torque:

Not sure if anyone other than Genius is making something similar.
The F50CSA does have the drive at the end, but I don't think it's available any more.

Thanks for posting!Here's a photo of the CAT 9S-1722, Snap-On TM4CSA and Snap-On SGT4B.
The Instinct handle on the SGT4B is much bigger which is probably why they didn't put a female end on it. You can definitely get a lot of torque with that big handle.
Regarding the alignment of the ball detent with the logo that someone mentioned previously... I don't think Snap-On is trying to align them. As you can see in my photo, the CAT is actually more aligned than both of the Snap-On branded ones. It's probably just coincidence.

Thanks for posting!
I placed an order for 2. The quality looks too good for the price.
The reality is I do not need another spinner,but with the pics you posted comparing the Cat with the snap on,I couldn't resist.
The Cat does look to compare very much with the Williams versus snap on hard handles. The snap on versions seem slightly more sleek/ slimmer.

That cat site got expensive for me.
Are there any other High quality Cat branded tools that I need to be on the look out for ?

*** Now I know why the all metal knurled M110 Williams get so much money. The small hole you see on the knurling, its for a ball lock to keep the handle from spinning when using as a driver. When using it as an extension you unlock it and the handle spins freely as you turn the shaft with ratchet, pretty slick.

LOL, and I thought I was the only one that liked socket spinners... Nice to know I’m not the only one that uses these!
Yeah, must be the angle I took the picture from - the 3/8" handle is about 1/2" longer than the 1/4" and definitely thicker.I'm curious on the SO Instinct handles - they look about the same size. My 3/8 handle is about 1" longer and a little fatter than the 1/4. Is the photo just deceiving?
I also have the TM4CSA and a 3/8 and 1/4 hard handle, but both with short ~1" shanks, and both short and long instinct and hard handle ratcheting so, no, you're not the only one.
Yes, that's my picture actually from a thread that I couldn't seem to find. I got 3 of them a few years back very cheaply on ebay, sold one and kept two. That extra feature is very handy to allow you to hold it steady with the shaft freely rotating inside the grip or locked in place and used as a standard driver.
Raising the handle frees it but no, the handle sleeve does not interfere with an extension or even universal joint. There would not really be a need to attach a ratchet directly to it. If using a rarchet/extension/universal/williams arrangement, the spinning handle helps keep it all aligned or at a desired angle. It's not a miracle tool or even necessary...just cool and well made.Logical,
Hope you don't mind that I used your photo? It's the only one I can find with the handle raised.
Question, I assume when it's in locked handle, hand turning mode, the handle is raised and when you have the handle spin freely while using the ratchet, it is lowered? I would thought it would be the opposite but reason asking is that if the handle is raised, wouldn't it get in the way of the ratchet fitting inside the female socket?
I found the orig. patent drawings for this spinner by Willard C. Kress

Re: The Green Tools ****
I already have the black set of these, but saw in the catalog that Snap-on makes a green version of the 1/4” (TM4CSAG) and had my dealer order me one. I love these spinner handles with the female square drive in the end - I find them handy in so many situations. This also extends my 3 week streak of ordering stuff my dealer didn’t even know Snap-on made...

Still listed. Don't buy it. Not all are the same. I exploded one like this where the female wasn't one-piece with the rest of the shaft. Mine was solid so I didn't know until it exploded. USA Craftsman, year unknown.There is one that appears to be in good condition on eBay right now for $12.00 plus $4.70 shipping (pics below):

Oh nice, that definitely wasn’t the case when I got mine.Their site currently lists red and orange in addition to the black and green.
The longer one is listed on their site in black currently.
No.Did Williams make a 3/8" drive version of the m-110?

Does anyone still make one? I know I've seen old C'man and S-K but I seem to have lost mine. Current S-K does not appear to have one. Has come in awful handy in a few situations. I mean a screwdriver style spinner handle with a recess for a ratchet or breaker in the back of the handle. Thanks!
Yes, they’re out there!Ones that can also act like an extension with a female on the handle end? We know Snap-On (TM9csa), Williams (M-106A), Craftsman (43393) and SK (40953) makes them.
Can anyone else provide another with a part # that hasn't been mentioned ?? Harder than you think finding one while doing a search.
Haven't seen any made by Germans/Old World or Japanese, not that they don't exist but no joy while doing a search or finding descriptions that describe it. Found none on KC Tools.
I wished Heyco made one with an extension option, they make nice small simple profile handles; like the one on their regular 1/4" spinner.

So, I just found out that an extension I bought a few months back is actually a Williams M110 with the locking sleeve. Didn't notice the two holes for the ball bearings to pop thru. Is there some magic to get this thing to disengage? I sprayed some lube in the holes, both bearings seem to move independently, but I can't see an easy way to get them both unlocked. Seems like pulling should do it, but it seems more stuck than that.Yes, that's my picture actually from a thread that I couldn't seem to find.

Appears to be a history of rust? Vinegar soak. Tap with soft mallet at M square, handle supported.
Actually, I was surprised at how shiny it was. It almost seemed unused. Except for the crud in the two ball holes.Appears to be a history of rust? Vinegar soak. Tap with soft mallet at M square, handle supported.
Never mind. Tapping the female end did do it. It was just cruddy lubricant dried in place that was the problem. Once I got it free I put the square end in a tap handle so I could spin it. Sprayed WD-40 in it. Crud is slowly breaking down, then we'll put some real lube in it when I'm done.Actually, I was surprised at how shiny it was. It almost seemed unused.

Did you mean to say the female end? Because the male end is already bottomed out against the shoulder of the spinner bit.
