content: I'm looking for a quality, compact powered micro screwdriver. Is probably overkill for most people, but I have severe tendonitis, making it very painful to screw things.From looking around, this is what I've found so far:General tools Ultratech, and its rebranded variations. Power: 2xAAAPros: CheapCons: Very fragile, underpowered, slow.Wiha 75989System 4 Powered Micro Bit Set. Power: 3xAAAPros: Good bits.Cons: Driver itself is poor quality.Proxxon MIS1. Power: 12V power supply neededBig and heavy (8 inches long, weighs 1 lb)Corded and requires separate power supplySetup has the largest footprint; takes up a lot of desk space, and extra cords to manageSwitch is purely on/off; variable speed requires a variable power supplyOut of those, I'm liking the proxxon the most.Is anyone aware of other options or ideas?

content: There does seem to be a gap in the market for a small, light powered driver that will quickly spin most of the thread of a machine screw, leaving the final tighten to do by hand.My ideal would be something small and light, which could spin an M3x10mm screw in under a second, with a slipping clutch or cut-out, which would then lock the handle to allow manual tightening to however tight it needs to go, or initial release when undoing.This Panasonic is the closest I've found so far, but more heavy duty than needed for machine screws, and top speed could do with being about 2x faster.It has a torque shut-off which has a very wide range, which is good.The charger is ridiculously huge though.http://www.tool-net.co.uk/p-336391/panasonic-ey7410la2s.html?gclid=CP2P0tH2970CFYbMtAodw2oA8w

content: I have been using this Bosh driver for years, and very stisfied with it and can recommend. Only thing to note is that it does not come with any bits, you need to buy them seperately. I have couple of long nose screwdriver bits with different sizes, and is very useful.This is fairly light weight, but not sure how micro you are looking for;http://www.bunnings.com.au/bosch-professional-10-8v-li-ion-cordless-drill-driver-with-2-batteries_p6200230

content: I think what all the manufacturers have so far missed is that there is a potential need for a power screwdriver where smallness, lightness and speed are more important than torque.I terms of time, manually tightening (or releasing) machine screws is a small proportion of the time relative to spinning in/out the rest of the thread.As soon as you remove the need for a big chunky battery, motor and gearbox, you can save a ton of weight & size.

They are well built, have an external speed controller and have all the options like the suspended arm system for a production environment. The controller is usually good enough/has enough speed so that you can do some basic drilling with it. I haven't been able to destroy one with various abuse.HMC has most of these but they are probably a bit pricy for hobby use. Ebay may be the answer.

content: I own the Panasonic model mike linked, I use it daily at work, saves my hands/wrists a lot of strain compared to using a conventional cordless drill/driver while sitting at a bench, as well as in the field. I share the same sentiment about the speed, I never use the lower speed setting, and wish the higher setting was faster. The length can be an issue in tight spaces but the handle does pivot and if in doubt I use a right angle attachment.

I'll mainly be working with m2 or m3 bolts, and I don't think that requires much torque. Speed though, is a priority.The CL-3000 looks very promising. 1000 RPM, wow (vs the Proxxon @150 RPM). And it's lighter as well.

For a long threaded screw often I feel it is tedious, sure its much faster than by hand, but still slower than it should be.Heck, i'd sacrifice some of it's torque for speed, when i first got it i was very very very amazed by it's torque, first thing i did was try to hold the bit in it still with my hand (because if i can hold it with my hand, i can screw with a screwdriver tighter) and i was unable to do so.

content: Yes ! I agree with you, excuse me for omitting this, It might be important to evaluate.I have a "big" screwdriver can screw 60mm (2,5"?) in less than a second, but the usability of this small this means that I always use this.my little mad-zone, about 200 4x60mm concrete walls screws, with the big tool, surely could have ended an hour before but ... the tendonitis can also come by holding and managing a weight tool.I think it's a good recommendation, of course with your warning, if for example 60mm in +/-5 secs. is an acceptable term.I think he has the strength to not break anything and help a lot for teardown, bench operation and casual (patiente) walls & large.

content: I really think there's a market for something like this - more like a "power assisted" manual driver than fully powered unit :Similar shape/size to a traditional medium-sized screwdriver - for smaller stuff, this is easier to "aim" than a pistol grip form factor.You grip it and it locks the shaft, like a normal screwdriver. For tightening you need to grip anyway so why not use this force to avoid the need for a mechanical clutch.An alternative may be a ring at the end that's pulled up/down to engage - must be able to do it without changing how you hold it.You press a button (or maybe a ring at the end and the shaft spins fairly rapidly, but with only enough torque to do/undo a machine screw. e.g. fast enough to fully spin a 12mm M3 screw in under half a second.Torque cutout, probably using motor current. The high speed also dictates that you want the rotating mass to be fairly small to avoid over-torquing.As power won't need to be very high, battery should be smaller than 18650 to reduce size/weight- maybe AA sort of size.Maybe an oval handle with battery/motor either side of shaft and a single gear to couple to the shaftReplaceable shafts preferable to using a bit holder near the end, to improve stability and maximise access (e.g. down recessed holes) If there is a bit holder, it would be the smaller 4mm type, preferably with some sort of locking mechanism.Maybe a set of long shafts for standard sizes, and a 4mm bit holder for less common stuff.Almost tempted to try designing something myself....

content: I've been using the Milwaukee battery powered screwdriver on my bench for more than thirty years. First iteration (circa 1983) battery was a bit weak, but so were most NiCd batteries of that time. Still the batteries lasted a year or so each if properly charged and cared for. I still have my 1983 version of this tool and it still works, but the last battery died years ago and it was a better deal just to replace the whole thing with a newer version with better batteries. The latest version of this driver with Lithium-Ion batteries is hard to beat. It's fast and the clutch system works great. For most screws, it does all the work for you. For tight or stubborn screws, the shaft automatically locks and you use your own wrist to start and finish torqueing screws. Weight is only about a pound and about one inch wide, you never get tired of holding and using it. The kit with two batteries is in my opinion the smart buy. This tool is not the go-to construction or machinist driver, but certainly a welcome addition to most work benches.http://www.milwaukeetool.com/power-tools/cordless/2101-22Single battery kit on eBay...http://www.ebay.com/itm/390706838886Two battery kit on eBay...http://www.ebay.com/itm/291072953197

I can guarantee that it's not intelligent enough and will quickly just be in the way and become annoying.New BMWs have intelligent braking to prevent you from rear-ending "things". But those "things" include bugs that splat on the sensor. Ooops. Maybe in the fine print the BMW manual states "No bugs were harmed in the making of this vehicle."Hopefully that screwdriver has a "Disable gyro" button.BTW this the same gyro in the other post?

content: I own the Wiha from the original post. It's fine with a nice set of tips. Not particularly strong, which is good for inserting screws and not so good for removing them. I like having a small kit with a very nice assortment of bits. The driver itself is okay; although, not really up to Wiha standards. The switch in particular gives little confidence that it will last. I bought this because of elbow tendinitis and because I'm a fan, in general, of Wiha tools.I also purchased a cheap Black & Decker lithium ion driver (LI2000:http://www.amazon.com/Black-Decker-Li2000-Rechargeable-Screwdriver/dp/B005LTNLDS/ref=cm_cr_pr_product_top). I find myself using this far more than the Wiha on my bench. It cost $20, the batteries last a really long time, and it has enough torque to remove any electronics screws. You do have to be careful when using it to insert screws though due to the torque.I don't regret buying the Wiha, but I'm not sure I would make the same purchase over again. I also agree there is a need for something a little more robust than the Wiha with better control than the LI2000 (or the other general purpose drivers suggested here).I'm not sure that I see the need for any of the higher price models suggested in this thread outside of a production environment where you need accurate torque control or extremely high speeds for quick and repeatable assembly.

I prefer the black and white color scheme over the red Milwaukee driver, but I cannot find the Panasonic driver in any local stores to check out. It is of course available on eBay, but at a premium price over the Milwaukee driver. That fact alone makes me like the Milwaukee a whole lot better, and I can live with the color. Torque is listed as a little bit higher on the Milwaukee driver, and I bet that is mostly due to its higher voltage battery.

content: We got one of those DeWalt gyro drivers to try out at work recently (along with a bunch of other cheaper drivers not worth mentioning), and I put it through its paces assembling a batch of 25 pendant boxes. With eight terminal screws and four housing screws each, I'd say 300 screws is enough to get a good idea of its usability.Thoughts in no particular order:Overall it takes some getting used to, but the gyro action is fairly intuitive. If I hadn't spent so much time using traditional variable speed trigger tools, honestly the adjustment probably would have been easier.The gyro control is actually rather nice for things like screw terminals where you constantly need to reverse direction. It's nice to be able to turn the tool one way to back off a terminal screw, stick the wire in, then just turn the tool the other way to tighten.You do have to make sure that you position the tool such that you can actually rotate your hand enough to activate it, which is sometimes tricky when trying to hold a terminal block and a wire in one hand while fastening the terminal screw.There's no apparent battery cutoff to prevent you from discharging the battery into the ground, so that doesn't inspire confidence as far as battery lifecycle. I'm sure there's a safety cutoff built into the pack, but better rechargeable tools have a built-in cutoff somewhere before that point to improve battery life.It's very good at rejecting pitch and yaw motions and only responding to roll. When the battery gets low it occasionally gets a little squirelly, but that's right at the point that torque drops off to useless levels, so not a big deal. I tried pulling the trigger and shaking the whole thing very vigorously in all directions, and even then it's very difficult to confuse it.Battery life is decent. I did about 2/3 of the job with the initial half-charge the batteries came out of the box with.The handle swivels to a straight screwdriver type configuration, but I didn't find that configuration nearly as ergonomic as the pistol config.I didn't try any terribly big screws, but torque seems to be plenty adequate for most general electronics purposes.I think I'd rather have something like a variable speed rocker trigger (squeeze in one direction for forward and the other for reverse), but the gyro isn't bad, and with variable speed, a variable clutch, and removable rechargeable battery pack for $90US, I'd give it 4/5.

content: I lovemy HitachiExcellent torque for its size. Easy to control speed and direction. Really comfy grip. Battery seems to go on and on before needing recharge.Dave really needs one of these. Watching him take out screws by hand on teardowns, even sped up, is painfull....

content: spec wise it looks very similar to the first makita I mentioned, 200 and 600rpm, no variable speed, 21 clutch/moment settings.Not so big selection it seems here in Norway, but so far I have found the panasonic and these makita's.

Only thing that gives me pause on the linked screwdrivers is the side rocker switch. It's hard to say how ergonomic that would be without holding it.

content: I bought one of the Hitachi drivers and am quite happy with it, bizarrely the rocker switch works quite well, although I have been used to a 'pistol grip' position for drill/driving for quite a few years!The rocker switch works quite well as an extra torque release mechanism as if you hold the drill like a pencil, when the screw tightens up then drill handle starts to twist away and this then pulls your finger off the rocker switch. When it first happened I was a bit surprised and the initial response was to then hold the handle more firmly but now I let it happen quite readily. I still use the torque settings as well though.It has been great for some chassis access, when I finally get in I am not so exasperated!

content: The side switch on these screwdrivers (Panasonic, Milwaukee, Hitachi) works perfectly. A well thought out design for use both in the angled pistol style position, as well as for straight-on screwdriver style use. You operate with your thumb (at least most would), and you quickly get used to the operation of the screwdriver.A pistol style grip would limit the design of these, and there are already many other screwdrivers available with pistol grips.The biggest limitation IMO with these screwdrivers is speed, which is not really an issue for its intended market. These type units would not be fast enough for repetitive production on an assembly line, but just fine for most professional and hobby bench use.

content: yes, It seems like most of them have 200 and 600 rpm, but the last makita I listed, have also 0-2000 rpm, I think one of the panasonics also have that speed range, if I reads the specs correct...

content: ah, good to know, removing those from my list then.To bad it seems like the two-speed ones doesnt have any variable speed, but at 200 and 600, maybe that is not a problem.I found that makita priced locally for approx $177, including two batteries, charger, tax, delivery and all,, which seems to be an good price for it.
