TOOLPAK TCT SDS-Plus circular cutter for 77mm holes in brick & block. First step for installing electrical back boxes. For SDS+ rotary hammers.
The TOOLPAK TCT SDS-Plus Electricians Circular Back Box Cutter is an essential tool for electricians and installers, designed to create the perfect opening for back boxes in masonry. Featuring twin tungsten carbide-tipped (TCT) blades, this specialised cutter delivers clean, efficient, and durable performance in tough materials like brick, breeze block, and concrete block.
It produces a precise 77mm diameter flat-bottomed circular hole, which is the critical first step in preparing an installation site. This initial round core provides a guide for subsequent steps, such as using a square or rectangular box cutter to finalise the opening for an electrical back box, ensuring a neat and professional finish.
Engineered for compatibility, this cutter has an SDS-Plus shank and is intended for use with SDS-Plus rotary hammer drills (weighing approximately 2kg) that feature a 'roto-stop' function. It must be used in rotary hammer action only to ensure effective cutting and to preserve the life of the carbide blades. This accessory is perfect for creating openings for sockets, switches, and other electrical fittings in solid walls.
