Hi all,
Does anyone use electrical box sinkers for sds drills, or know if they are any good ??
I need to chase out for approx 20 double sockets in old plaster/brickwork, and wondered if it is worth investing in one of these, rather than drill and bolster them all out.
Any feedback would be much appreciated, before i go and waste £75.

I bought one from screw fix and it,s a pile of crap , it is useless on tough brick , only any good on thermal block but that stuff is easy by hand , your better off by hand or using a small grinder (lots of dust) if you can IMO.



I second what stevie h says. You just can't beat the tooth tool in front of the hammer.

If you ever think of using a box sinker in an old vicky house, then forget about it .... unless you want half the render of the wall to come down ad well. Just something I unfortunatley experienced whilst on a job.

They just don't warrant the price you pay for them IMO.


I use the Armeg sinkers.
Again best used on thermalite/breeze blocks & they do save time when sinking multiple boxes. The chase bit is fine on same blocks & does work well on most bricks.
In older buildings with sand/lime mortar you'll have problems with the brick work moving when using the sds sinkers/chase tools.
Engineering bricks, dont even bother getting the sinkers out the van.

Scutch chisle & lump hammer. ;)


Have only ever had good results with thermalite/breeze blocks. Stays in the back of the van now.

junk ! and i still laugh at the quality of tools been sold by so called Trade places.

"Silverline" etc !!!!!


If you want to destroy lots of wall, knoxk the plaster off the other side of the wall and cause lots of rubble to fly in all directions they can't be beat!

Scutch and lump for me. If you have the chaser out, then that will do a good job of getting the box mostly cut out. It's an art that requires practice, and you do have to plaster afterwards, but because of the extractor it's minimal dust.

Only work well in breeze block walls. Take too long to cut out in brick. Quicker with SDS drill and chisel. Total waste of money.


Total agreement with what's gone before.

Bought one, tried it, gave up with it, got shot of it (or was that the first wife?)

Seriously a lump hammer and boulster or my old faithful Makita hammer drill chisel (getting good with it now)


eye dont bother with em meself either, i use a brick hammer for chopping out in thermalite and cordless chissler drill on the more stubborn.


There you go, just send half the cost of what you were going to buy to the "Buy the Forum a Drink Fund" c/o either Bane or me (to go with the recipes: we will then be able to recommend the right aperatif to drink with them) ;):D:cool:


Buy you a drink any day, but you can keep your so-called recipes! Fish? Urgh! lol :)
