Powered screwdriver for precision bits and electronic work?

1/4" to 4mm adapter

or these

PH000 bit, 1/4" drive


They do make 4mm powered drivers. But depending on what you're working on, a powered driver can be too bulky to reach where it needs to go.

I had a 3/4" drill, that thing was a monster for torque. And, while standing on a ladder, a spade bit got stopped - drill didn't care, it kept going. And, when it spun around in my hand, the lock-on button got pushed by the side of my hand. I was incredibly lucky to escape serious injuries - and I won't tie extension cords together (to keep them from coming unplugged) ever again. I've always wondered what happened to it; it just disappeared one day. I presume one of my kids borrowed it & left it at a friend's house.

That happened to me one time. I was drilling with a spade bit and it got caught on something. My arm slammed into the floor joist, the spade bit twisted/warped and wrapped around itself, and then my drill broke.

A motorized precision screwdriver is asking for trouble. First, the appropriate amount of torque varies greatly from screw to screw and you likely be ruining them on a regular basis. Second, it's often hard enough to keep them on the tip until they start threading and any turning/spinning is just going to make you lose the screw.

It can't possibly help.

I disagree.

Using hand drivers over and over can mess up your hands and wrists pretty bad. I can post pics of my alien bumps and trigger finger as proof. If you use the right tools and use them in the right way, you will be fine. You don't just jab a drill with the biggest bit you can find and pull the trigger til something happens. There are some things that I need absolute control over, but those are in the minority. Motherboard screws are the only thing I can think of ATM.


Anyways OP: Check out my bits that finally came in. .25mm 1/4" hex shank phillips bits. Perfect for some really tight places I need to get into. They came from China (but were made in Japan?) so they took over a month to arrive. But I'm very glad I have them.

On the right is the standard #2 phillips and the middle is a 2" #1
