My wiha tips fit into it, but I broke a gear (metal actually) playing games with it (it should be more then good enough for most screws, but its slow, but I still prefer it to turning something I find the motion uncomfortable.) By playing games I mean twisting it back and forth while its on holding on it really tight. If I used it more often I would make a special reel for it, since it has a disconnect feature (screw thread cord) As far as miniature non torque controlled ones, I actually really liked the 20$ unit i bought from Lowes. For some reason plugging it into a control box with dials on it irritates me much less then plugging it into the mains. It's not terrible if you have the controller on a work bench next to the soldering iron controller. The one I have is mains powered with brushes but that one runs on a controller. If you can step on a sturdy table or chair to plug it in its not so bad to use one. real weak one but you need a 24vdc psu for it The secret to using this shit is to put a power strip on the ceiling next to a hook. 800$ or so new, but you can get em on ebay cheaper. You set the torque with a special key and it rotates real fast when you push down. I've tried Dremel's li ion driver and a cheap electric screwdriver they're too slow for me.Ī nice production screw driver is an ingresol rand unit. I have a more expensive drill with a really good variable speed trigger and instant auto-brake, and it takes much more attention and time to use that to insert tiny screws without overtorquing/stripping. The torque limiter is insufficient to insert really small screws, but with a tac switch and FET in place of the clunky trigger, it is easy to feather the power in tiny amounts with a light touch on the handle (pressing downward but not holding the handle too tight) to get it to coast into a light stop and finish manually. But it spins at ~2k rpm for fast screw removal. The inertia carries to a gradual stop, but once stopped it is locked so you can torque the screws, manually, like the Wowstick. It happens to have an auto brake that doesn't stop instantly and a pretty light mass. My favorite cordless power screwdriver for electronics is a small cordless drill, 2 cell lithium, 2 speeds, no electronic speed control. If I had to open and close laptops, I'd buy this in a heartbeat. 1000 RPM and slip clutch down to half an inch lb, plus or minus 5%. ![]() These are fantastic, but I have never been tempted to buy one for home use, due to the cord. Downside is these hi speed production electric screwdrivers all seem to run off mains, only. For high volume work, you would want something probably 500+ rpm with an adjustable torque limiter that goes down to nothing. Or you can use the long hex bits in a handle to break loose or torque down screws, and take the hex bit out and use it, loose, for all the mindless spinning. +1 A manual jewelers screwdriver is a heck of a lot faster than the 200-380 rpm you can get with one of these electric screwdrivers. Too little the contact heats up and you have a problem, too high and the contact, case and wire deforms too much, and compromises reliability. In the mid point it could be an useful tool, with a controlled torque screw driver for a few N.m capability for general purpose and working in electrical panels where torque is specified for different terminals (usually in the order of 1Nm to a few) and the force applied is quite critical for such applications. Having a impact driver for someone who deals with much tighter and bigger screws makes a lot more sense than this tiny ones. Mobile phones have a lot of screws but they are quite short and doesn't take much force, using a thin, small screw driver makes a lot of sense as it's lighter and you can spin it fast with your fingers. ![]() and yes, it's a screw driver which has a gyroscope to measure the rotation you give to it and starts rotating in that direction with a torque or speed (don't know which, maybe both) proportional to the amount of rotation you apply to it. ES121 are cousins with the TS100 we all know. ![]()
