I decided that it's a good time to give myself the luxury of (dis)assembling furniture with an electric screwdriver. For the odd table or chair it's not a big deal, but for painting a room and moving the furniture out then in, it is.
So far I figured that two features are essential in an electric screwdriver:
- A clutch. Without a clutch I can too easily strip the wood when I am reassembling.
- Gradual speed. Until I know that I've chosen the correct size of the tool, it's wise to first go slowly. Hence a trigger that starts slowly is important.
These two constraints basically eliminate the cheaper tools I see on the market.
But I also see some very serious models. Are there any features I'm missing besides the two just mentioned?
It would have been nice to get a tool that also helps with bike work ("use torque of 5 N.m"), but it seems one cannot rely on the precision of the torque on the electric models and a manual torque bike wrench will still be needed as a separate tool.
Whoever closed the question has almost surely read it inattentively. I am well aware of the obsolescence issue, and I phrased the question very carefully to be sure it'd apply 20 years down the road. But anyhow, happy to delete.
