Cutting door frame into breeze block wall - how?

[garycat]

I have an internal breeze-block wall, non-load supporting, that I need to cut a doorframe-like hole from top to bottom.

Should I use my SDS drill and stitch drill loads of holes and then chisel out the remainder, or buy an angle grinder with 230mm disk. I reckon this will be neater but will create far more dust.

Something like this

I've done it a couple of times using the drill method, it's dusty and messy but prob not as bad as a saw. Doesn't take too long with a 20mm drill once you get going.

Hire shop. Stihl/Partner and ask for thr 14" blade version.

When you say 'breeze block' do you mean dense concrete blocks or celcon? If it's celcon I think I'd stitch drill enough to get an old hardpoint saw in and do it by hand. Less dust, fairly quick.

cut it with the disc cutter and have someone standing by squirting water on the cut and there will be very little dust, if you stitch drill it and you want to fit a door frame it will be awkward fit

Errr, I dunno - the house was built in the 1970's if that helps, so probably more of the cinder block type rather than the concrete Aero chocolate type thing.

You'll still need a lintel in it, even if it's not load bearing.

Give the width of the opening, thickness of the existing blockwork to the builders merchant or check online.

I seem to remember that the circular saw was the most professional approach.

Yep, I was going to suggest that as well having seen one in action , no matter what the material, thats the baby for the job.

P.S. Its brick / concrete chainsaw

This is the difference!

I think the standard response in such cases is 'and video it for out amusement'.

Stitch drill and finish with a cheap concrete hand saw, or hammer and bolster in a mostly downwards direction (to join the stitched holes). A sturdy door frame will suffice if you can't be bothered with a metal/concrete lintel.
