Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking. See the How to Ask page for help clarifying this question. If this question can be reworded to fit the rules in the help center, please edit the question.
Well this is a very short question so I will try do give you an detailed answer :)
First you need to figure out how this map tiles need to be organized. There is the Tile map service standard that describes how to form URLs, but there is also the slippy map way how OSM organizes the world of tiles.
Next is about legal aspects. Google Maps map tiles are protected by copyright and the same for all other commercial map providers, so you need to buy them. OSM tiles at the opposite CAN be published under a free license, but they don't have to. Also there might be technical restrictions on such kind of bulk downloading. For example the osm.org tile servers have tile usage policies to protect the volunteered infrastructure. Otherwise your requests might get blocked.
If you keep this notes in mind, you might be happy with tools like (newest!) Mobile Atlas Creator or JTileDownloader.
As you like to transfer a huge amount of tiles, that will take very long due to this technical restrictions, you might consider to setup a complete local rendering stack, or use Maperitive as a Desktop solution (at least KOSMOS had the feature to create tiles)
