Don't know if it's the same in USA, but we use either single or double 35mm deep metal back boxes for most standard domestic outlets here, which need to be recessed, in this instance, 25mm deep into a solid concrete block wall.Not sure what you are doing, but if you are cutting block walls have you tried an angle grinder with the proper blade?
Thanks, but that sounds pretty dusty and time consuming, especially in concrete.First I cut out the square outline with a 4" angle grinder with a diamond blade, like Brian said. I make an "X" in the center to help break out the pieces without chipping the outside edges. Then I drill two or four (depending on 1 or 2 gang) 1.5" holes with an SDS 1.5" core drill, to the proper depth, with a rotary hammer. This removes most of the material. You can go 2" if you have a pretty hefty rotary hammer. Then I chuck up the 1" and 1.5" SDS chisel bits to clean up the opening.
I don't use a pilot on the 1.5" core bit, I just hold the shaft in one hand while pressing that hand against the wall till it gets started.
Been using Milwaukee coring bits, they last many years.
Neat looking tool.but the pilot bit breaks and is not too easy to rapidly track down a replacement. Just wondered if there were any similar, fairly dust free and fast products that anyone could recommend.Thanks
Good advice, but was also just seeing if anyone knew of any potentially better products as well.My advice would be to call the manufacturer and order direct. If they won't do it, get one of their distributors to order a bunch for you. If this tool is really one you use a lot, call them and place a big order for a bunch of pilot bits. Quit buying 2 or 3 at a time and purchase in bulk so you won't run out!
I enjoy hearing these odd to us Yanks terms for things and appreciate the efforts you make to offer translations for them. Once in a while tho......Fair Faced concrete...
how about if it is a block wall, the wall gets fished? The manufactures page does seem to show CMU wall.I enjoy hearing these odd to us Yanks terms for things and appreciate the efforts you make to offer translations for them. Once in a while tho...
re the 'back box' I am thinking another item gets attached to these with the actual device mounting to it but as 220/221 asked where/how the F do you run the wire?
is. I have never heard anything close to this or what it references to.pi!!ock
