I am in need of a core bit to cut through a tile floor and concrete foundation for a tub drain. Will this bit do the job? Will I need a hammer drill?

This bit will have trouble going through foundation concrete. You should get a wet core bit for that: https://www.amazon.com/dp/B017JO7K98 You can definitely use a hammer drill, but you must turn the hammering function off

I need to drill a hole through brick to accommodate a 4 inch vent pipe. Will the 4 inch bit do the job, or do I need something slightly larger?

We drilled through a 8 inch cinder block wall with this bit. We also needed a 4 inch vent pipe...in our case for a dryer. It was difficult to get a standard 4 inch vent through the hole we bored. To have it work we inserted a sleeve through the wall made from sheet metal that was probably a little smaller than 4 inches and attached a 4 inch vent pipe on the inside and an outdoor vent on the other. This solution was easy and worked out great.

Is the sds plus arbour available to purchase separately ? https://www.amazon.com/gp/product/b077r6tzny/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=utf8&th=1

I didn’t receive one with mine but the seller was great and sent one right out . I’m sorry I don’t know if you can buy separately
