About this product
This Faithfull SDS Plus square box cutter is designed to form recesses for single electrical back boxes in masonry and concrete. It is used together with a Faithfull tungsten carbide tipped circular cutter (FAISDSBOXCUT) to complete the recess. The cutter produces a 77 x 77mm square recess, suitable for standard single back box installations, making it useful for electricians and contractors carrying out first fix work or flush-mounted electrical accessories. It is intended for use with small 2kg SDS Plus machines fitted with a Roto Stop feature, operated in hammer action only with the rotation stop engaged. It is not suitable for use with larger 5kg machines.
