Though a lot of people we’ve talked to don’t like the PS10 form factor — many seem happier with the drill-like PS20 pistol-grip style — I’ve always been a huge fan. The Bosch PS10 is hands down the best tool I’ve found for general light assembly and disassembly around the house and shop. For example, I used mine to quickly remove and re-drive about 30 machine screws to re-organize some 19″ rack mount gear in my studio. What makes the PS10 so great, IMO, is that the combination of its straight/90-degree shape and a trustworthy electronic clutch with soft-start — the trifecta for tasks like the ones I described above.

Admittedly, I’ve never really desired a drill-type chuck on the PS10, even though it does bear a strong physical resemblance to any number of small right-angle drills. But adding a chuck to the PS20 did wonders for its general usefulness. Does the same hold true of the PS11?

The specs seem to confirm that the PS11 is pretty much a PS10 + chuck. You get trigger-controlled variable speed (0-1,300 RPM) and torque maxes out at 101 in-lbs. — right in PS10 territory. But you also get a longer (and probably more comfortable) trigger on the PS11, a couple of small LED worklights, as well as a battery gauge and (most critically) a 3/8″ auto-lock chuck.

While I haven’t seen one of these in person yet, I suspect that (like the PS10) it’ll fall into a pretty narrow niche market — but will be the tool for that niche. If you’re constantly drilling small holes in relatively soft material in tight spaces, the PS11 would make a lot of sense. Now the big question: Who’s in that market? Maybe cable runners? Electricians? Help me out here. Is this something you’d use? How?

Expect to pay around $130-$150 for the -2A kit, which includes the tool, charger, two batteries, and a soft case — pretty much the same price as most of the PS-line of drivers.

    I actually really like the idea of the PS10 in general. I have the PS20 and I’ve lived without a chuck by purchasing a decent set of quick-connect drill bits. So I use it all of the time for drilling pilot holes, etc. Obviously if I need to drill larger holes, I just use a big old drill with a proper chuck. But I haven’t found this to be a deal breaker.

    Now, with a PS10, I’ve been wanting one for use in assembling cabinets. I suppose the same could be said here. Buy some quick-connect bits and drill your pilot holes for drawer guides, or hinge screws. Then switch and be on your way. I think for this use case it’s preferable this way, because you can easily switch to a driver to drive the screws. The only situation I can think of where it could be an issue is that the quick connect component to the drill bits I mentioned typically add some length over a standard bit of equivalent size. That could be a factor for REALLY tight spaces. There the PS11 could come in handy.

    Honestly, I see this more as a matter of Bosch covering more of the market by addressing personal preferences. (i.e. someone may not like the quick connects – or they may have a heavy investment in standard bits and don’t want to purchase new drill bits). May also open up the market for those who desire a standard right angle drill, but who don’t have a need to a really heavy duty version and will value the light weight and portability of this cordless version.

    I have one of these, since I figured it would be a companion for the PS10 I already have. Like the PS 10, it is not something I would use often, but it is a lifesaver then the need arises. I’ve used both in custom auto work, plumbing, electrical and home theater installations. There are times that no other tool can work its way into an odd spot like these two can because of the adjustable heads/chucks. As much as I liked the PS10 for this sort of duty, I was disappointed in the PS 11 after living with it for a while. The PS11 body is quite a bit more bulky than the PS10, so getting into the tightest spots is not quite as easy. There is plenty of power, but no clutch. The PS10 has an electronic “pseudo-clutch” the stops the motor at a set torque limit. This is not too big of a deal, since the primary function of the PS11 is drilling. There’s plenty of power to be had.

    The PS11 suffers from a design flaw as I soon discovered. I began to have problems locking the chuck head in the 0 degree (axially to the body) position. I would have to force the chuck into position. This only got worse, so I opened up the drill to find out why this was going on. Turns out there is a small ribbon cable the supplies power to the (very convenient) LED above the chuck. In the 0 degree position, this cable was being pinched by the internal structures of the chuck head and the transmission. There is really no room for this little cable to move about, and only the tendency for it to hopefully bend in a particular direction as these two parts move is the only thing keeping it from being pinched inside the mechanism. Unfortunately, the cable in mine had a tendency to move into the wrong area when flexed by the movement of the pieces inside. I tried my best to reroute the now damaged cable in the lacking space, and might have to forgo using the 0 degree position if it should creep back into the space. Either that, or remove it entirely and lose the LED lighting as a result.

    I hope Bosch comes up with a production fix for this rather silly decision, it will make this unique tool much more reliable.

    I have been using my PS10 for about 6 years now, and it is hands down the best cordless driver on the market for mechanical tasks such as the one mentioned in the post. I do a lot of work w/ appliances, and it is a lifesaver when working in tight places, especially when you need good control of the action. I have said many times that it could use an on board LED, but he addition of a chuck is a waste, IMHO. There isn’t anywhere near enough RPM or torque for drilling operations w/ this tool, it wasn’t designed for that. The added weight and length is a step in the wrong direction. My cordless drills (the ones that have chucks) always have quick release adapters chucked and ready for the use of hex shank bits. Only when I need to use a hole-saw or a larger bit do I remove the adapters. The PS11 would need the same adapter for most jobs, and there goes the compact size, along with some of the capability.

    I have one bought it for tight angle drilling KMS tools had them for super cheep it was under a $100 for tool only
    I have the ps41-a which is a sweet little impact gun
    and the multi ocilating tool

    it is a pretty good little drill but not enough torque to do much drilling but for the odd thing I need a right angle drill for it works anything else I will reach for my 18v stuff

    I have the PS11 and it is worth getting if you already have batteries and can spring for the bare tool. It is a little bulky compared to the PS21 or PS31 but comes in handy for tight spaces and cabinet assembly. I have not noticed the flaw that Phil discovered but maybe my wiring fold the opposite way by luck alone. Altogether the PS line of tools is worth every penny and I have become a Bosch fanboy because of them.
