Firstly, some references for you:
The obvious difference between BB30 and BB86, is that with BB30 the bearings are pressed directly into the frame; with BB86 the bearings are pressed into cups and the cups are pressed into the frame.
Also BB30 is natively for 30mm diameter spindles and BB86 for 24mm spindles.
The X-Tools tool will install both as it has adaptors to cope with the different internal diameters of the bearings and the cups.
But you will need both the other tools to remove them: not only are the diameters different, but with BB86 the shell guides the tool; with BB30 there is no guide for the tool.
Personally, I find Park Tool overpriced for what they are: Cyclus are my "nice but pricey" choice.

Thanks so much for the resources, much appreciated!
To complicate matters, I took a look at the bb30 frame today. The token bottom bracket in it that came from the factory looks to basically be a reducer made of aluminium that is pressed into the frame, that then holds smaller bearing that allow the use of Shimano cranks. I've attached a photo of the bottom bracket with crank removed.
Should I a) punch the bearings out of the reducer and replace them with the same bearing type, or b) remove the whole unit and replace with a larger bb30 bearing kit like this and then a adapter like this?
Or does it not really matter? Neither seems like a great solution tbh
Right, I'm driving myself mad with modern road bike BB standards!
I've bought a few new road bikes over the last year, most of which have different press-fit bottom brackets. I want to be able to service and replace them all in the future myself, rather than having to take them to a bike shop every time. I also need to service or repair the BB on my winter bike imminently as it is creaking badly.
I've got the following bikes:
To remove and re-install bottom brackets across all 3 bikes, I think I'll need http://www.wiggle.co.uk/x-tools-press-fit-bottom-bracket-installer/ and https://www.amazon.co.uk/gp/product/B00426BAGQ/ref=ox_sc_act_title_1?smid=A3P5ROKL5A1OLE&psc=1 . Is that correct, or do I also need https://www.amazon.co.uk/gp/product/B00426ENBU/ref=ox_sc_act_title_2?smid=A3P5ROKL5A1OLE&psc=1 to remove the BB30 on bike #1?
Then the bottom bracket that was on bike #1 from the factory appears to be out of stock everywhere I look. What are my options for replacement bottom brackets? Can I just use any BB30 bottom bracket?
