Industrial quality and craftsmanship-EXTRA TOUGH
These are my personal favorite locking bit holders because the locking mechanism is easier to use than any other. Bits easily insert and it’s automatically locked and it stays unlocked when you pull it forward. True one handed operation. Wera makes very high quality products and this is no different. I own several of these in different lengths and have used them for years without any problems. I even use them in my most powerful impact drivers and they’ve held up perfectly well. The collar is steel with hard plastic rings (black and green) on the center portion of the exterior. The black and green rings on the outside are not fixed so you can hold them safely to steady the bit holder and they wont spin in your fingers as the bit holder spins while driving fasteners. Works with 1”(25mm) insert bits and power bits. To insert a bit you can simply insert the bit easily and it will be locked regardless of where the locking collar is positioned but if it is open in the forward position the action of inserting a bit will also slide it back into locked position. To release the bit you pull the collar forward and the bit will pop out part of the way while still being held from shooting onto the floor by the magnet. When the collar is forward the bit is loose and held only by the magnet and can easily be removed with little effort. The magnet is in full contact with bits when the collar is locked and is very strong. Enough to hold 2.5” (70mm) long screws onto a bit easily. The steel collar is tapered and in the locked position is far enough away from the end of the holder that it doesn’t get in the way for most driving applications. Toe-nail style screwdriving or driving screws at an angle to the surface of the material is not a problem with this bit holder. I hope this is helpful.

Solid 1/4" hex bit extension
Using this as an extension in conjunction with Wera Zyklop 8784 A1 Adaptor between a 1/4" torque wrench and 1/4" hex bits for tightening breaker screws when added depth is needed. Provides an excellent/stable connection to the adapter and the hex bit, and that won't come apart accidentally -- very good in a live panel. If using a torque wrench, determine how the extension affects the measured torque.

Excellent Screwdriver Bit Holder / Extension
Wera Rapidaptors are the best locking screwdriver bit holders I’ve found. Compatible with all 1/4” (6.3 mm) DIN 3126-C / ISO 1173-C (standard 1” bits) and 3126-E / ISO 1173-E bits (power bits, typically 2” and longer) as well as other non standard 1/4” hex bits. Works with Megapro double ended locking bits, but has to be manually locked, other Megapro double ended bits also fit but are only held magnetically.

Decent quality, not great value
I like buying high end tools, but this one is not that much better than the cheaper Chinese/Taiwanese version. I think they can make a better connector. It is more balanced and spins "true" compared to the cheaper ones, but still not perfect.

Sherman Quality
High quality! They sent me a pack of 5. Not sure if that was a mistake or how they come!

Holds tight, no fuss
This quick change adapter is worth every penny. Makes changing bits way faster than dealing with the chuck and it holds different style bits tight, with no fuss!

Super chuck
Used it for everything from door and lock installation to wiring and electrical. Working fantastic so far! I thought the magnetic pull would be stronger for screws sticking to the bit but I think it’s mainly to hold a bit in place- having said that it still really grips a screw very well, even up to 4” deck screws. I tried it as a test, you have to shake it to get it to fall off. The collet design and how it holds a bit in place is perfect 👌 a+++++. Extremely happy with this purchase. Haven’t used it but a few days so we’ll see about longevity. Wouldn’t hesitate to buy again if I broke it though.

See the title. The way this holds bits and makes they release a simple single movement is terrific.

Si adatta perfettamente al porta inserti 817 R SB. Funziona perfettamente anche con altri inserti. Tempi di consegna ok.

Great locking bit holder, length is in between the two other Rapid Adapter bits Wera offers

Best bit adapter I've used, easy one hand action. You can insert a bit in the locked position also which is awesome. Bought this longer version as a complement to the short one as I'm so satisfied with it.
