Like any professional with enough years behind them there are probably over 10 drills in my possession, from old/worn cordless drills to corded drills handed down from previous generations, to a cheap SDS chisel I've never used since the project I bought it for...
The drills I use these days are:
BHC - Delighted every time I use it as to how great it is (power vs size). Makes me glad I spent the $ every time!
TID - Just got it, don't use impacts much but glad to have one for those times they're the ideal tool.
T18 Compact - My fave drill ever! Once upon a time I had a T18+PDC+CXS, but after some consideration (and buying the BHC) I sold the PDC & CXS for a second T18 compact set.
In my professional setting, drills are used so often I have no issue spending a bit of extra cash to spoil myself with a tool(s) that is a real pleasure to use.
Centrotec is key too! I love having a quick change system but hugely appreciate the tighter tolerance runout of centrotec vs the std ball detent hex bits widely used.
