Calidad Diamond 20mm Hole Saw


This core bit is specially engineered for the purpose of high-speed drilling and a long lifespan. The vacuum brazed diamond side protection offers a smooth and clean cut with minimal chipping. This is a more economic version of the tool, but it still delivers great performance. 

Calidad high-speed dry/wet diamond core bits are the most effective solution for drilling holes in kitchen countertops, bath /shower walls for faucets, handles, soap dispensers, and others.
