Re: Running all cordless power tools from Mains adapter ??
Well there are not a lot of options available for corded stuffs now a days. For example combi drill or impact drill most of them are cordless. Also from cost point of view if we can buy cordless body only then it would be much cheaper than corded one. And buy no batteries, just use that one adapter to run all cordless body only tools. That was my idea!

Re: Running all cordless power tools from Mains adapter ??
There are many mitigating factors.
Safety - many sites demand lower voltage equipment (110V) which necessitates a heavy transformer. Then there's dragging cables around - particularly when the area of work is away from source of supply.
Need - most basic power tool requirements involve little demand on 'power' i.e. you're not always using tools to dig holes through walls or break concrete so simple hole drilling, wood cutting (2nd fix) and planing etc doesn't need a heavy power connection.
Those tasks that DO require lots of power still have their dedicated cabled-devices but as battery energy density increases even these will turn to cordless.
Security - a backward step IMHO as your portable tools are much easier to filch than a corded version! Can't be long before they are 'coded' to the owner though.... easily achieved using modern technology and surprisingly not already available (I'll take my usual 10% for the copyright from anyone who's contemplating introducing it though
)
Practicality - the use of a mains power unit is just one more added complication to go wrong. Cables will be necessarily 'heavier' due to higher current requirement of low voltage tools especially if any 'length' is considered. Such cables also increase cost considerably.
Cost - as already mentioned with cables plus a power supply that can deliver such high currents at short intervals is relatively complicated and prone to stress failure if improperly designed/built (at additional cost).
As a 'get by' option for someone with a load of battery-powered equipment that has NO batteries left then yes, purchasing a power pack may indeed be cheaper than getting a few new batteries - but not by much.
A low-weight lithium battery 'belt' (and I've been told they do exist) would be more useful. Short curly cord, universal connection, and extreme longevity would just about cover all areas.

they dont have inbuilt obsolecence so last say 20 years + where as battery are more like 3-5 years hard graft
they also tend to be more powerful although battery is catching up a bit but not in your senario
