Audited Supplier *Back Box Cutters are a labour and time saving system designed to cut sockets in blockwork and brick walls for the siting of electrical back boxes.
*Used in conjunction with lightweight 2kg SDS fixing hammers with a rotation stop function.
*The system requires the use of a TCT circular cutter and either a 77x77mm single square box cutter or 77x154 double square box cutter depending on the box size to be cut.
*Only recommended for use in blockwork and soft brick, when cutting into hard brickwork use the SDS chisel provided with square box cutter to clean out remaining brickwork.
*Make a centre mark at the point where the box is to be set. Use the 8mm SDS drill bit as supplied with the circular cutter to drill a pilot hole at this point. The bit is then removed and the circular 77mm cutter fitted into the drill, insert the guide rod into the pilot hole. Engage the rotary and hammer action and cut a 77mm hole to the required depth.
*The circular cutter should then be removed and the box cutter fitted into the drill. Insert the guide rod of the box cutter into the pilot hole and aligned the box at 90 degrees to the wall, with the rotary action disengaged hammer out a square hole to the required depth. The supplied SDS chisel can be used to clean out any remaining material and clean up the hole if necessary.
*When using the double square box cutter, three pilot holes are required . Using the two outer holes cut two 77mm holes to the required depth and follow the instructions above to finish the installation.
