The type with injectors/splitters should be regarded as "poor man's PoE" (no slight intended; I use a lot of it) and is not standardised (unlike 'true' PoE). It does have the benefit of enabling non-PoE devices to be powered (over Ethernet) though.
Makita do Nemesis bits that will also go through rebar and they’ve got sizes up to 32x450mm.
I’ve got a 25mm x 300mm one and its a beast but goes through engineering bricks like butter. It was £30 from memory though ..!!
