Sinking back boxes by hand can be a slow and tedious process, but with the Armeg EBS Square Set Box Sinker, you can kiss that old-fashioned chisel-and-hammer method goodbye. This convenient attachment makes drilling square holes for single socket boxes easier than ever before.

First, create a pilot hole with a 6mm Masonry Concrete Drill Bit (like the T3066 06 from CK Tools), then clear the majority of the material away with the EBS Tri-Cut Cutter (EBS.ROUND.SET), and finally square off the opening with the Square Box Sinker. Talk about quick and easy!

This Box Sinker is ideally-suited to cutting holes in softer masonry materials, including medium density concrete block, softer brick, and Thermalite block. For harder materials, such as Engineering Brick, please use the 80mm Hard Material Box Sinker Chisel (EBS.BSC.HM).
