Hey everyone! I've got a question about three types of screwdrivers: the M4, the M12, and the Installation Driver. They all seem to serve similar functions, mainly for driving screws without damaging them. I find the M4 interesting because it looks like it can fit in tight spaces, while the M12 seems simple and possibly less useful. The Installation Driver, on the other hand, seems to cover the same ground but might have some extra features. Can someone help me understand the differences and why I might choose one over the others? Am I wrong about their purposes?

It really depends on what you're working on. For instance, the M4 might not have enough power for wood screws or tough materials, but it’s great for small fasteners. The M12 is versatile for driving screws into wood and has a clutch for delicate tasks, but it’s bulkier and can’t fit in tight spots like the M4. The Installation Driver acts like a drill, so it’s better for high RPM tasks. My only gripe is its reverse switch placement – it’s in a weird spot! Pro tip: use it with a drill bit and driver to switch tasks without uninstalling between uses!
If you’re picking just one, the Installation Driver is the way to go! It does everything the other two can, plus more. The M4 is nice for niche tasks but isn’t essential to have as your only tool. I have both the M12 and the Installation Driver, and honestly, I can’t recall the last time I grabbed the regular M12.
Yeah, the M4 is pretty handy for quick jobs, though!
I use the M4 mostly for delicate work, like HVAC repairs, and it helps reduce fatigue during repetitive tasks. The M12 is great for DIY stuff at home, especially when climbing ladders. They all have their unique uses, and I've learned which tool to grab based on the job at hand. The M4 is quirky but its clutch feature is super useful for fine work. As for portability, the M12 is compact enough to carry around when I'm on scaffolding or ladders.
By the way, I tried the vessel screwdriver once, and it was amazing for smaller tasks!
The M4 is like a portable screwdriver for tight spaces, while the Installation Driver is a bit beefier for carpentry tasks. I love that the Installation Driver has magnetic attachments and can stand up on its own while I’m working! But yeah, the M12 has its place too – I guess it depends on what projects you’re tackling.
Why not just use a drill at the lowest settings or stick to a hand screwdriver? Those electric ones don’t seem to pack much torque!

Totally agree with you there!
