Wera 889/4/1 Universal Rapidadptor Bit Holder, 1/4" Drive x 75 mm, 05052503001

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.

Good addition to the collection

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.

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.
