Electrical Box Cutting

[atownsend]

Hi,

I'm planning to fit quite a few extra double sockets around the house and bought a double box cutter and tri-cut cutter. I just checked though and it says they're not suitable for 5kg SDS drills which I have.

Just wondering if anyone knows why they're not suitable and also if there's a better method of cutting out for the back boxes. I've got about 30 to fit around the house in total and it's all into red brick.

Cheers,
Andy

The socket sinkers are not too good on brick, On red brick I find the best method is to stitch drill the hole and knock out with masonry chisel, a little time consuming but most methods are with brick.

Cheers, I'd read that actually so I'll probably send them back I think.

They have there uses, I carried an armeg kit around with until the shafts snapped, ok on clinker/breeze blocks, soft stone and low density concrete blocks, but brick, quality stone and medium-high density concrete they don't cut it (excuse the pun) So I am now happy carrying masonry bits, and various SDS and hand chisels, the scutch comb chisel is a useful addition.

Draw around the back box you want to knock out and the I use a 10mm drill bit with masking tape around to the depth(say 25mm) then drill as many holes as you can inside the outline of the back box. Then just tap the masonry away with a chisel.
