New Wera 4:1 turbo screwdriver

[techieman33]

It's an interesting idea that I haven't seen before, though maybe others have something similar out there. It has an internal mechanism inside the standard shaped screwdriver handle. If it's engaged you get 4 turns of the big for every turn of the handle. And disengaged it's a normal screwdriver. It's something I wouldn't mind having, but I wouldn't use it enough to justify the hefty price tag.

and a quick video of the mechanism

So is this a 2 handed operation then? It sort of looks like it.

I've seen the Kobalt ones at Lowes. Not sure how well they work. I never paid much attention to it cause I rarely use ratcheting screwdrivers. Interested to know if it's gimmicky or not.

I'm struggling to wrap my brain around how the reduction works when there is little or no resistance on the actual screw.

My guess is that you'll have to hold the lower portion of the handle. In the video it's not moving while the upper portion of the handle and the bit both turn.

I picked up one of those Double Drive models at a pawn shop. It didn't like high torque when using the fast speed. Ended up damaging the internals somehow as it stopped working smoothly after about 20 minutes. I'm thinking the fast drive is for running in screws till they bottom out, then go to low speed for final tightening.

Ouch that’s pricey

It's one of those things that looks cool, but isn't worth the money like the Snap on ratcheting screwdriver. You can get a halfway decent cordless drill or impact driver for that kind of money.

If you have the space for it usually you have the space for a 1/4" impact with a bit holder.

Nice idea, but i'm not paying that for a screwdriver.

Yeah...for that money something like the Dewalt gyro seems more appropriate.

In fairness, Wiha SpeedE is even more overpriced I guess.

I have a mac overdriver and another brand. I like them. You hold the the bottom and turn the top to engage the gears. When engaged you have very little torque though.

I have had the Mac oerdriver for 25 years. I used to use it a lot, but do not use it anymore since cordless toolshave become available

Anybody that has not tried the Dewalt Gyro screwdriver... MUST buy one. You will not regret it. Superior to any ratcheting screwdriver.

I dunno. I have one - two actually, one in the workbench and one in an i-boxx portable kit - of the convertible straight-pistol ones. I still use ratcheting screwdrivers quite a bit.

But yes, the Dewalt Gyro is a great tool. I use it more then all my other power tools combined, 10x over. For repetitive screw removal or driving there’s nothing better. The cheap little Black & Decker Gyro pistol thingy was pretty great too, though it can lock up at moderate torque.
