The Unifit countersink core bit by Prado is the stone-working companion to the Unifit Outlet Single. A one-step diamond bit, it drills the 1-3/8 inch hole and the 1-1/2 inch countersink in a single pass, so the outlet sits perfectly flush in natural and engineered stone backsplashes. Use it wet at around 500 RPM. For wood and MDF, choose the Unifit Forstner bits instead.
