As part of a newly renovated bathroom and utility room I need to create a hole for a tumble dryer vent through the external wall which is plaster-brick-brick-render from inside to outside. Its seems my two options are:
(1) Buy a core drill piece (circa £50) and get busy
(2) Drill a series of smaller holes with the (lengthy) masonry bit I already own and chisel out the gaps to create the hole.
I feel like the second option is going to give a shoddy finish at best given that it is an old victorian property and the walls are prone to a bit crumbling around any significant drilling. Should I just bite the bullet and buy the core drill bit?
Will my current drill be man enough for the job?
Option 1 for a better finish.
You can hire the drill bit.
Your current drill will not be man enough, although it does depend on the brickwork you are drilling out. What will happen is that you will place the drill bit on the wall surface and the drill bit will not go round but the drill in you hand will (snatch), it will hurt, it will make you wish you had a bigger beefer drill, you will probably not complete the job because of it.
You might be able to hire a 5kg+ SDS at the same time as the drill bit.
