Wera - 5052502001 889/4/1 K Rapidaptor Universal Bit Holder for 1/4" Hex Drives, 2" Long

In a nutshell: Best all around quality, Best design, Best features, Best quick release bit holder. I use quick load bit holders on my 12v Milwaulkee Impact drivers. The small quick release on the impact drivers are small, difficult to grasp, and have to pull collar out in order to push the bit in. Awkward!! But this Wera quick release loader eliminates binding & makes rapidly changing bits an absolute breeze! This Wera tool is phenomenal & not only easily handles 1/4 shanks, but also the short 1 inch long straight shank bits (e.g. phillips, blade, star, square, etc.) with ease. Previously I used the DEWALT DW2505 Rapid Load Holder but I found it was too long (3inches) and awkward. This Wera is easier to grasp & eject, more precise holding bit alignment and 33% closer to the work for better accuracy, top quality, and smother operation all the way around than the China made Dewalt DW2505. It ejects everything very smoothly. And the magnet is designed to not over power the bit so that the bit slips out perfectly when released. No 'back holding' or tugging to remove the bit. This bit does it all and in a much more convenient, less bulky shorter 2in length vs 3in for the Dewalt. The Dewalt wobbles more and encourages bit walk due to it's longer length & looser tolerances. The Dewalt is also harder to control vs the shorter compact length of the Wera. Precise, under control, and easier to pop off the bit for the next one this Wera has increased my drilling speed, comfort & efficiency. It has eliminated a hassle and made things fun again. Wera is German made and the quality shows. It's an easy one handed operation,...Push in a new bit to automatically lock,... Pull back the collar to release and eject. I have an injury to my thumb and find the Wera collar is much easier on my joints to load /eject vs the Dewalt collar. I will be purchasing more of the Wera K Rapidaptors'. Hands down, this Quick Release Wera is in a class by itself. All of the 5 star reviews were correct. It's a pleasure to recommend a great product that deserves 5 stars with the good feeling that my purchase is helping support a free, democratic country.

I seem to have accumulated quite a few of the very short bits. Don't know how, actually, because I usually buy at least 1" long, and 3" and 8", etc. Also it seems I am running into more times that I need different bits on one project because for some reason they used different screw heads. I like the general quality of these bit holders and especially that you can insert/remove a bit with one hand because when you slide to open it stays open. Then you have to close it. Most others I have used it is spring loaded so you have to use one hand to open it and the other hand to insert or remove the bit.

Perfect bit holder for quick swap of bits. Lock and unlock feature prevents dropped bits. Very happy with this purchase.

Great bit holder. I use one at work almost daily for the last 8 months. I personally have one as well. Never had an issue. It is magnetic despite some reviews claiming otherwise. Other negative reviews claims "it wobbles", well duh, it's not meant to be a precision drill bit holder. It's not meant for a CNC machine or a drill press...lol! People should change there expectations when it comes to "bit holders" for drilling. None of them are perfect for drilling, and they all wobble to some extent. Want less wobble and more precision? Use a drill chuck. Your ignorance should not be blaming the tool for it's unintentional purpose, which is not precision. This is a fantastic bit holder, made by man with flaws. But it far exceeds other brands by a long shot.

I love this but holder. It locks the bits in nice and tight, its magnetic and changing bits is a breeze.

(Update 7Jan22) I only use the non magnetic model, (889/4/1). I lost it for a short while, and immediately bought a second one. After a year I found it. Now the non magnetic one is on both my impact drivers. (Original review) The SD label on the item listing refers to the packaging. It is the same as this item. (added 2APR2020) This is a good tool. Swapping bits is pleasantly easy compared to the other options out there. You have to fight with the ones from other brands, and then use this item to understand that opinion. The ease of use is so nice, I'm benching all my 2 inch bits and I'm going to use this with bit inserts going forward. I will continue to try to find something that does a little more. This Wera bit holder is extremely easy to use with Milwaukee bits. They pop in and out with ease. This holder is much better at inserting and releasing the bits compared to the Makita version. The Makita is just plain irritating to use, because it doesn't release the bits. The Wera retaining system is very good, and easy to manipulate. The bits do not fall out when the screw is done, like they do in my other magnetic bit holders, (Ryobi, Milwaukee, Makita, Stanley...). I have both Milwaukee and Wiha 2 inch bits, and they are both fantastic. I would like to have a simple solution to make them better at holding the fastener in both downward and horizontal pointing angles. I also have a large collection of Milwaukee bit inserts, and a small collection of the Makita inserts. I have the Makita B-35097 Impact Gold Ultra-Magnetic Torsion Insert Bit Holder. It does hold the screws at weird angles, with the insert bits. However, it is clunky to use. The bits fall out in use and the bits are frustrating to change in and out. I want this part to also hold the screw in position. That would be perfection. I thought the metal ring around the bit might be a rare earth magnet, and slide down to hold a screw in both downward and horizontal pointing angles, but it does not. Dewalt makes a part that comes in a 3 pack, that slides up and down the normal 2 inch bits from most brands, and magnetically holds a screw in place. I will try them out, but I would prefer to use something like this item, that makes bit changes ridiculously easy. The built in impact driver bit holders on both of my tools (Ridgid and Makita) are okay, but this tool is so much smoother, that I will just leave it installed. The search continues. (Updated) It appears Wera offers another version, in line with what I want. It is the 887/4 RR. It has the magnet built into it. I just ordered that one. You will also find the 887/4 RR SB. They are the same product. The "SB" refers to the packaging. I will post a review for that as well, once I have my hands on it. I'm keeping both, if the 887/4 works just as smooth. I have two impact drivers, and it gives me options for both. (Update 24Mar20) I like them both. I recommend both. If you are pulling and installing screws, use this tool. If you are just installing a bunch, use the 887/4/1. I included a picture of all the ones I have for reference. The 889/4/1 is the smaller one of the two with green accents. See my review of the 887/4/1 if you want to learn more there. It has the same picture. (Update 2Apr2020) I've been working on a project lately. I found this, and its friend, the 887/4/1, are very good at holding all brands of bits, even ones that sometimes slide out of magnetic holders. And they hold them tightly. I really appreciated this, as I have one set of nut driver bits that keeps falling out of the other four bit holders I own. Problem solved!

Im a handyman and this bit makes my life easier.. top quality great value.. defintely buy again if i need to. Must have for any tradesman

Great tool

très bien , fonctionne comme il le doit.

very good product

Portainserti a dir poco fantastico!!!! Nel mio lavoro utilizzo l’avvitatore con portainserti tutto il giorno sostituendo l’inserto in uso anche 40/50 volte in un’ora.Ho provato svariate marche di portainserti ma tutte con scarsi risultati,l’inserto si sgancia da solo o rimane bloccato e nn si toglie più..All’inizio ero indeciso se prenderlo o meno visto il costo elevato rispetto alla concorrenza e avevo paura di buttare altri soldi trovandomi con l’ennesimo portainserti deludente..ma devo dire,con estremo piacere,che mi sono ricreduto alla grande non appena l’ho provato.Il sistema di aggancio/sgancio dell’inserto è impeccabile,una volta agganciato l’inserto rimane ben saldo e per toglierlo basta una sola mano.Fantastico!!!Seppur con un costo elevato sono più che contendo di averlo preso,i soldi li vale tutto fino all’ultimo centesimo secondo me,per uno come me che lo utilizza nel quaotidiano non può esserci di meglio!!!Super super soddisfatto!!!

Been using wera products for a long time, from screw drivers, to bits, to allen keys. This attachment was affordable, small, compact, built well and works well with other brands of screw drivers too.

Le meilleur porte-embout à verrouillage mécanique pour embout long. Après avoir testé presque toutes les marques de porte-embouts, celui-ci est mon préféré avec le DEWALT DWA3HLDFT/ DT7524. Le Dewalt est parfait pour les embouts courts, car il est fin, et le système de verrouillage est à l'arrière. Le Wera est parfait pour tous les autres cas, avec une facilité à insérer les embouts, et une facilité à les retirer également, uniquement quand on enclenche la bague de déverouillage (en la poussant vers l'avant). Le verouillage mécanique de l'embout est parfait, avec très peu de jeu.
