content: I need help finding a precision electric screwdriver that won't strip small screws. (If it's versatile for larger projects even better).This will be mostly for things like laptops, phones, and small electronics projects.So I believe I need something with reasonably high RPM, some way of limiting torque, and a clutch, right?I saw there's the ES120 and ES121, which look neat, but not sure how useful in real life.For industrial grade - it seems I'm looking for brands like Kolver, HIOS, Ingersoll Rand and Delta Regis. I foundthis page, which lists some models - but I'm not sure how to pick one from another?They all seem to be plug-in, which is annoying, but it doesn't seem anybody makes a cordless one at this level (I assume there's technical reasons for this).An American company called Mountz also offers quite a few models - the E series and VZ series are their basic ones. I think the VZ series is a rebranded HIOS. The clutch adjustment on their basic models is apparently quite fiddly according to the person I spoke to on the phone.The German company HS-Technik also offers the TorqBee range, but I can't seem to find it for sale anywhere online.What have people used, and can recommend?

content: I can give my opinion on ES120 and ES121.Resume: They are a bit useless.The ES120 have more torque but less speed, also it seen the magnetic force to hold the bit is lower.The ES121 have less torque but more speed, it hold the bit better.For laptops you will need to loose the screw first with manual screwdriver, the force required for the first turns will stuck ES12x. Even with some smartphones you will need to use a manual screwdriver to give the first and/or last torque.But we can't ask much from a 4.2v motor...So if you do lot of dis/assembly you will want go a more capable screwdriver, something that plugs to power directly, with that you go use a handy pencil format and lightweight.For me, i use the ifixit small screwdriver, the top rotate free, so i press it down and with same hand or the other i turn the screw driver fast. It defeat ES12x when you need to use a second screwdriver to do the work.

content: I've got one of the "800" type commonly sold in China, and find it works reasonably well, although in my case this is for occasional use. They come in 3 sizes, 800, 801, 802, according to how big the screws are you want to deal with.For example, seehttps://www.aliexpress.com/item/EU-Plug-DC-Powered-Electric-Screwdriver-800-Small-Power-Supply-220V-801-802-3C-4C-6C/32247338812.htmlThey take special bits, but you can find all kinds, including unusual types like Y, etc. Note that the different size drivers also take different size bits.There is also a cordless version now available, although I haven't seen them outside China.https://item.taobao.com/item.htm?id=589311318607
