Unboxing: 14.4V Impactor


The 14.4V Impactor ships in a Bosch-blue hard case that’ll seem familiar to anyone who’s purchase a large Bosch power tool in the last few years.  Inside you’ll find the tool, two batteries, a charger, and a manual.

Looking at the tool itself, it’s easy to see the PS40’s heritage.  The direction control and trigger are identical — selecting 0-2,800 RPM and 0-3,200 BPM — and while the exact pattern of composite and TPR varies a bit, it’s clearly designed to accomplish the same task.  The shape of the tool just behind the chuck is identical.  The chuck itself is also a 1/4″ quick-release type.

A small clasp molded into the handle just above the battery holds a single driver bit (included — one side Phillips, one side slotted) for easy constant access.  Also at the bottom of the handle, Bosch added a sliding “tool hook” to help you hang the 14.4V Impactor on a tool belt.  The hook’s plastic cover also extends down to protect the battery’s latch mechanism.  The batteries are 2.0 Ah, 14.4V, NiCds and are standard in the Bosch 14.4V line.

    Great review guys.. very informative. Looks like I have another tool to save up for. 😀

  2. Stephen says:

    When can I buy it! Hopefully a they will develop a dedicated drill that will fit in the lineup.

    I have the 12v impactor… I don’t think I will be buying this, but it would be a REALLY nice tool for the electrician

  4. Michael says:

    Nice review. I bought the PS20 after your earlier review and use it most every work day. Does about 75% of the work I need a drill/driver for (right now). I could see how an impact driver similar in size would be handy to have around.

    Hmm, better show this review to my wife, less than a month to go until my birthday….

  5. bc says:

    Great review! I think it is a solid tool… but feels too big for my hands. Nothing has beat the 14.4V Ion Panasonic in terms of ergonomics. This thing is perfect. Now if Bosch made a mini recip and run on the 10.8s I would purchase this…

  6. Phillip says:

    I agree with what’s been stated so far. Most of my fastening needs are not the abnormal-sized screws so I think this would be a great addition to my tool box. I would like to see Bosch really (market) the heck out of these 10.8volt tools with a combo set and maybe add a true drill and a flashlight for real cheap.

    Great review! Thanks!

    Now I have yet another tool to add to my want list. Any idea when we will start to see these on shelves (or better yet online)?

  8. Eric Corson says:

    Thanks for great review. I think these would be great for home woodshop or a locksmith. I have used same makita 12v impact for about eight years mostly for sheet metal screws at work but also must have for wood deck screws. Gone through about 3 pairs of batteries, though, and the NMH batteries no better than NiCad in my opinion. The LiIons seem like the way to go and I suspect reason this new COOL driver did so well against its big brother. I must soon replace my makita, but hopefully with a brand with a SYSTEM that includes the flourescent light and blower I cant live without-so I hope at least Makita-(hint,hint)-is listening!

    I discovered this review while looking for something completely different. A happy mistake. I have a PS-20 and use it constantly. I was thinking of getting a second one to keep on the truck, but one thing stopped me, and that is the torque limits of this unit- it does a fantastic job on all but the longest screws, when it seems to simply poop out.

    I still find my ancient Makita 9.8v will beat it every time, but can’t compare to the portability. Now I can investigate the new Impactor and make a move. I heartily agree with posts calling for more uses for the 10.8 battery- for one job I adapted it to fit a Black & Decker electric caulking gun (don’t ask!) and it worked great.

    The annular light is a small but brilliant development, even though I made fun of the PS-20’s wonky one-eye LED, it still is pretty useful I can’t wait to see how much trouble the new one will save.

  10. Al says:

    As someone who had first hand knowledge of this and all of the Bosch tools, I can tell you that this tool will be a HOT seller. As a Bosch rep, I sold a ton of the PS20 to HVAC contractors who loved not having to lug their 18V up into the tight spaces. However, I could never get them to get rid of their makita impact drivers. This tool will handle that little issue.

  11. clueless says:

    I got to play around with the PS40 this weekend at a sidewalk sale. The Bosch rep told me that it was 179.95. Impressive power for its size. I think that it would be great for removing panels . I hope they are going to sell it in a “tool only” option because I already have the PS20.

    Now if they made a Litheon 10.8 small recip saw that uses jigsaw blades like the old B4050 and 3294EVS inline jigsaw, I would buy one in an instant! I’m still looking for an inline jigsaw with no success.

  12. Random West says:

    Ran a little demo today, 2 fresh batteries and 2 pilot holes. Simple but effective. Check it out:

    Awesome review of the 10.8V Impactor against its bigger brother. I was quite amazed that someone had taken the time to do such a practical video review on such a new tool. I have been studying the Impactor at Lowe’s for a couple of weeks, and this helped me make up my mind on the purchase.

    Great job and congratulations!


  14. Thanks for great review.

    ith the help of Bosch appliances, the things you do every day are easier and more enjoyable. Whether its the industry-leading silence of our dishwashers, the ingenious engineering and time-saving features of our cooking products, or the unmatched efficiency and gentle care of our front-loading washers and dryers, youll find that life with Bosch is an exciting and liberating experience, giving you the time and opportunity to focus on what matters to you most

  15. Bobby Joe says:

    Great review. I will add my two cents to the guys who requested an in line jigsaw. I almost bought the Black and Decker series for this one reason. I hope Bosch will consider adding one to the 10.8 Litheon line.

  16. Lane Smith says:

    These are great service tools. I wish that Bosch would make a 30 min charger for 12 volt automotive use. I have one for my Dewalt tools and it is a great addition to my service truck.

  17. Jeff says:

    On my SP 20 when you depressed the trigger all the way it seems to stop and nothing happens batteries seem to be charged what could be the problem
