Kitchen sink waste advice

Couldn’t find a T with inspection hole at Screwfix but did manage to procure a space gun to drill for the waste pipe.
First I bought the core bit and sds adaptor.
Then went back and bought the pilot drill that didn’t come with the core bit.
Also had to get a comedy length 8mm masonry bit to pre drill from inside. Oh and it knocked off a big chunk of the brick.
Gave up core drilling after about ten minutes as I’d only gone through about half a brick and my arm was falling off.

You need a Tee and a Cleaning Eye. Fit Cleaning eye into unused socket of the Tee. https://www.bes.co.uk/polypipe-40-mm-white-swept-tees-91-1-2-solvent-11816/ and https://www.bes.co.uk/40-mm-screwed-access-plug-solvent-white-11861/
(Unless you're using Compression or Push Fit waste, in which case you can dismantle things if need be!)
Cant help with the drilling, a lot will depend on the hardness of the brickwork you're trying to get through!

Welcome to deaf'n'dumbing
As said, a swept tee and a cleaning eye.
Always drill from outside in with brickwork
Try a 6inch core 10feet up a ladder through wet bricks
No chance I’m going up a ladder to do the new shower waste pipe. Will have to get a man in. 
Back on the drilling this morning. Core bit stuck in the wall, creating its own tool holder. Going against all advice I’ve upped the speed and put my hip behind it, otherwise it’s a jittery mess that barely moves. Should be through next Tuesday.
Oh Lordy, I’m through! Giving it a bit of welly and riding the clutch proved successful. Will go inside now and hope it’s a tad easier to meet up in the middle.
