I bought a 4V cordless screwdriver and a 3/16ths drill bit with a hex shank. It's the perfect combination for making technic axle holes in solid bricks or plates, and it's small and lightweight enough to easily fix in your toolbox.

I found other models that are more powerful, charge faster, and have better features, but I like this one because it's small, cheap, and does the one thing I occasionally need. Sometimes a simple basic tool is better. :)

I do the same with an old  3.6V NiCad drill.  I had to replace the worn out  NiCad cells with a Li-Ion cell + BMS. Still its slow rotation speed is perfect for reaming holes in 3D printed parts to 4.8mm for Technic pins and axles.
