Yes for a diamond core and ideally an sds drill if it’s breeze

Hello again Shaun , I have fitted a underground junction & running pipe to the left for w.c.
I'm unsure which connections to use, first the one coming up from ground at that position also the one that goes through the wall , or can I justify use the 87.5 socket bends that I've been using .

here is an update of job finished , i ran a new drainage pipe to existing soil pipe ,job done . works well with no problems ,
