Could HIRE one? Although to be fair, having used one it is a dangerous heavy tool, especially when cutting into a wall.

Agree 100% with the above, I used one once and would not touch one again.

Had you considered a 9 inch angle grinder? A lot easier to handle but still dangerous.

The last time I needed a door aperture the builder I employed chain drilled the hole, so much easier and a lot safer.

I hired one from Jewsons - it was very cheap to hire and worked well. We used it primarily to cut blocks when building a wall.

I too would urge caution Ian if using them to cut through a wall. They are heavy, the Gyroscope effect is very strong, kick back can rip it out of your hands and when cutting out a door sized hole you have to hold the thing above your head.

I was strongly advised by my builder mate not to do it myself and let him do it.

VERY glad I did.

Let a professional do it, and they may offer advise as to whether a lintel is required.

I created a plastic tent with a vacuum cleaner attached to extract the dust, donned a full set of clothes and overalls, face mask and goggles, and all I wanted to do was cut away a non-load bearing wall in a tiny en-suite using an angle grinder. Duh! holding that up in an unusual position, fought that torque, started the vertical cut and it burst into flames - now get out of that, deciding whether to run, drop it, or cut the power first. Luckily I cut the power, then dealt with the situation.

Get advise from a professional.

Cutting a hole in a wall with one of those things and no experience is a recipe for disaster, just try cutting something on the flat and you’ll see what I mean. Don’t hire one, get someone with experience to do it

I have to agree with all of the comments above (and I actually run a hire shop so have these on the shelf)

They are brilliant bits of kit, but are heavy, noisy and when you are cutting a doorway you will have more dust than you can think of! (even though they normally have water dust suppression)

You will have to cut from both sides as the blade isn't big enough to go through both the brick & blockwork, and also with them being 2-stroke, not recommended for use inside a building unless you have plenty of ventilation.

You can get 'concrete chainsaws' that will do the cutting in one go, but again get a professional in to do it.

I don't recommend using a 9" angle grinder to do it, as depending on the grinder, the blade won't cut through the brick or block completely and you will have a broken edge - this can be cleaned up, but lots more work and dust

macafee2 · 2nd January 2019, 08:47

Hence why I am not asking to borrow one.
I will use a lintel.
Angle grinder is an option, not sure if it is anymore or less dusty using one.

any ideas how much to cut the slots to form a new doorway? Only want the slots cut. nowt else.
