Looking to buy a non-professional (occasional home DIY use) multi-purpose power-drill like the 'Skil' range by Bosche (although I am open to other brand / makes that fit my budget). I have an option of buying 300W, 450W and 650W. I rarely (if ever) need to drill metal -- but do need to drill wood and masonry (including concrete). I am almost convinced that the 300W would perhaps be too underpowered, though I am not sure by any measure. The model 450W and 650W models seem to have only 2 differences, i.e.:
- 650W model claims to be able to drill 13mm in steel, while 450W claims 10mm
- 650W model has an extra side handle, I guess to get a better grip while using 2 hands
The price difference between 450W and 650W is significant enough to consider saving the money for other necessary tools for my tool box, unless the additional power is justified.
