Tool storage chest &amp; tool bag

Good set of spanners, good set of screwdrivers. 

Impact driver, screwdriver, jigsaw. 

Set of bits for the impact driver, mixed set of drill bits / screwdriver bits for the screwdriver, mixed set of blades for the jigsaw. 

Hammer, tape measures x2 (because you can never find one when you want it). 

Voltage pen, electrical tape, duct tape. 

Couple different size wrenches and a couple adjustable spanners, also a socket set. Pipe cutter is also useful (the kind that tightens itself not the cheap ones)

2x folding workbenches. 

Don’t go super high end on things. I use Bosch pro for my electrical tools and as a DIYer doing a full home renovation they have done exceptionally well. I aim for buying higher quality tools, but buy it for life for me doesn’t need to be the same quality as someone working with the tools daily or even weekly. 

You can get all the above for probably under 2k and be able to do most any job in your home. 

Aside from that a compound mitre saw or / and circular saw aren’t bad investments. 

It really depends what do they want to do with the tools?
