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.

This thing seldom leaves my drill. I’ve had it so long that I don’t remember how long it’s been. I used it every day in my job for several years and often for the three years since I “retired”. It works just as well today as it did when I bought it. The bits are held snugly in place with no wobble and they “pop” right out when released. It does exactly what it’s supposed to do exactly how it’s supposed to do it, every day.

As Bruce in the other review said, look no further for a bit holder. I too, have been looking for the ideal power bit holder (the longer bits, not the short insert bits). I do believe that this can hold insert bits as well. The requirements for an ideal bit holder for me was 1) small form factor (at most 1.5" of protrusion and not fat), 2) built in magnet, 3) locks bits securely, and 4) tight tolerances (less slop in bit movement), 5) free spinning outer sleeve, 6) one handed bit changes (pull on the sleeve and out comes the bit) and easy insertion of bits. Is there another bit holder out there that fits this description? Believe me, if there was, I would have bought it, especially if it was available on amazon. So far I have 5 bit holders and that's not counting the regular, non-locking, magnetic holders. If you count those I have about a dozen. The price isn't too bad either. One minor con is that the magnet isn't as strong as I'd like, it holds insert bits pretty well but that may have more to do with the locking mechanism. It does pick up screws but barely. I've tried the ring magnet version of this bit holder but that model requires you to have the screw in contact with the ring in order to securely hold it. I do love the fact that when you pull on the sleeve the bit pops out. I no longer have to use one hand to hold back the retention ring and then use my other hand to pull the bit out. Or vice versa to load bits. No more "holding back" the ring to put in a bit. What a great feature. This along with my Ridgid palm nailer (see my other reviews) is a must have for your tool collection. Leave this baby in your cordless drill/driver chuck and you wont be sorry! Now if I can just find a good drill bit set with quick change bases...

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.

(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!

I wish I had found this years ago. When screwing projects together, every 3rd or 4th screw would pull the bit out of the magnetic bit holder. If I was lucky, it would stay in the screw and I could pop it back in. But often, the bit would come out, fall to the floor and end up under the workbench and I'd have to grab another one. This holds the bit very securely while still being easy to swap out tips. Saves me a lot of time and lost tips.

Great help for anyone who uses a drill to drive screws.

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.

Goede kwaliteit. Super handig in gebruik. Wisselen van een bitje gaat moeiteloos met 1 hand. Eindelijk geen bitjes meer die aan een schroef vast blijven zitten. De houder is licht magnetisch.
