Review on Diablo SDS Plus 4 Cutter Carbide Hammer Cutting Tools in Industrial Drill Bits by Jordan Ford

broke at third hole of brick wall leaving shank in hole making it impossible to use mounting hole. Material - soft brick. The shaft did not overheat and did not touch the fittings or other obstacles. I drilled to the full depth the drill bit allows for 5" screws. The chisel is not strong enough to drill the deep holes it was designed for, even in soft brick.
