STURDY & DURABLE MATERIALS: The cutting blade of the diamond hole saw is made from a premium grade of diamond which provides more effective performance than conventional carbide or bi-metal hole saw. Easy installation: the ceramic diamond drill bits should be connected to an angle grinder. Drill a pre-drilled hole to start drilling so that the saw does not move from the desired hole position. HIGH PERFORMANCE: The ceramic drill bits for pots have holes on the body to ensure chips can be effectively removed while the saw blades rotate at high speed. SMALL CARRY CASE - The 8-piece diamond drill bits come in a compact box that does not use the crown. You don't have to worry about one of them missing. Wide application: the core extractor ensures a clean and precise hole on most rigid and abrasive materials such as tiles, granite, marble, other stones and porcelain.
