Yeah I opted for the 1/4” hex version in the kit with the 89mm bits. Then I got the KK 62 kit with all the security torx and security hex bits as I’m constantly using those type of bits. If I want to adapt to be a socket driver then I’ll take my hex to square adapter out of my tool check plus and adapt to 1/4” square. I also then have a few extensions to throw in the mix to help out. I think it’s a great setup!
Nice ratchet. I think your physics is spot on. Similar to using a cross-bar style lug wrench. If you pull on one side and push on the other, the torque is doubled.
A T handle also doesn’t require you to squeeze the handle to stop it slipping. Adding that squeezing force is going to weaken the amount of rotational torque that your hand can apply, I’m pretty sure.
I have the wera kraftform 400 RA 17 piece set with 16 long 89mm bits and the rapidaptor T handle in a very nice textile case. The set contains hex plus and torx bits very commonly used on bicycles. For sockets I use a little adapter and is working fine. For me is better than the square drive but both are very good tools. They are not cheap but for me is worth the price. On the other bicycle set from wera they are using stainless steel bits and you don't contaminate the screw heads on your bike. This T handle just provides the right amount of torque for this kind of work. 👍
Take the width of your hand (or the T-handle, if smaller) and divide it by the diameter of the screwdriver handle, and you will have a rough estimate of the increase in torque with the T-handle driver. I love the idea of a T-handle driver, as it would greatly decrease the chances of cam-out with Philips bits. Cool stuff.
The torque coming out of your twisting arm into the tool is the same regardless of tool, so the only difference here is less force your fingers might feel when applied towards the outer part of the handle instead of when gripping a thinner round handle. So, as far as screwing something with the forearm essentially straight on, the T handle should give more relief at the hand, but not an increase in torque. I think the improved sense of input loading he’s sensing is less force in the hand for the same torque applied.
As much as I love Wera and as nice as this tool is, you could buy three of the fixed version of this T handle from Wera for the same price as one ratcheting version. I have the fixed version in my tool box at work and it will do exactly what you need a T handle to do, personally I don’t feel the price difference is justified for the ratchet. You can almost stretch to a full on 1/4 drive Wera Zyklop socket set for not much more than this T on it’s own.

I think the same for most, if not all SNAP-ON tools. I don’t care for their antiquated designs and the price is stupid high. WERA, PB Swiss, KNIPEX, VESSEL are my main go-to’s. They, to me; are worth the price.
It appears that the ratcheting mechanism on these ratcheting T drive and their ratcheting screwdrivers are all plastic on the inside and the outside for that matter the levers plastic. So it's plastic in and out.

It looks like an awesome tool for working on dirt bikes and motorcycles. Thank you for the review! You did a great job!

I like all the black friday tool hauls that I missed out on the sale lol

Ahhhhhhhh!
One more thing to add to my EDC
This might be good for a tap driver, because they typically have a t-handle shape for balanced threading.
@3vil3vis
Thank you for the suggestion. I have been looking for something to do just that.
interesting. Not sure I would chose that bulkier design over the Fix it Sticks Ratcheting T Handle
It’s a different kind of twisting motion using the arm. I think for people with wrist pain this could help.
I’d like for the torque test channel test to see how much more torque you get from a t-handle driver over a standard screwdriver
You mean before it's destroyed?
At least 3 beans.
T-handle ratchets are great for running fasteners on or off. Breaking torqued bolts loose is for ratchets, etc....
“Material from my skin” doc do you mean your skin 😂
I want a shopping spree in Doc’s tool box
Have you seen or own a Wera Koloss?

I wish you would compare the Fix it Sticks Ratcheting T Handle as well. Thanks.

Wera stuff is nice and works.
Just really hard to pay what they ask.
In what capacity do you use your tools?
Check out the Felo Ergonic K Handle. Kind of a ratcheting transformer.

Felo looks perfect BUT has way too much play...
Indeed there is play in it but I still find it useful.

Easy way to check is to use a torque wrench, see how far you can get with the screwdriver untill you can't make it click, then try the T handle.
How come euro ratchets are labeled L and R and american ones On and Off???
👍
I don't think this Wera is worth it for the price. A few other ratcheting t-handles out there. I just don't think spending this much is a smart idea.
Wera has a hidden lifetime warranty on any ratcheting device, nobody know this because Americans don’t read the product info on the DE website ;)
Tbf most brands will replace a broken tool if you’re nice about it.

Its worth it cause im a tool rebel
You don’t have to buy a Mercedes. There are plenty of not so expensive cars out there with an engine and four wheels as well
Woof

Hazet 863Q is more compact and rugged.
Look
