Tool selection comes down to three things: fit, bond and grit. If you are starting in concrete and stone work, buy three diamond tooling first: (1) a 125 mm diamond saw blade for angle-grinder sawing, (2) a 125 mm diamond abrading cup wheel for surface smoothing and edge work, and (3) a 1–1/4 in wet diamond core bit for pipe and conduit holes. Together they cover 80% of residential and light commercial projects.
