What core cutter set for 40mm and 110m waste?

[bilabonic]

Hi all

Looking to purchase a core cutter set.

I will only be using it for 32/40mm waste.
Soil pipes amd 4" extractor fans.

This seems good for the price but has varying feedback?

I would also like to extend the arbour for longer reach.

I also have access to a proper 240v core drill but unsure if it's SDS or not?
