VEVOR Diamond Hole Saw with M14 Thread, Vacuum Brazed Diamante 20/25/32/35/40/50/60/68mm, 2 Discs, 1 Box, Tool for Ceramic Stoneware and Granite Tiles

Robust and durable materials: The cutting blade of the diamond hole saw is made by premium diamond which offers more efficient performance than traditional carbide or bimetal hole saw. Ease of installation: Diamond drill bits for ceramics must be connected to an angle grinder. Drill a pilot hole to begin your drilling to prevent the saw from moving away from the desired hole location. High Performance: Ceramic drill bits for pots feature enlarged holes on the body to ensure that the filing can be removed effectively while the blades rotate at high speed. Lightweight portable case: The 10 diamond drill bits come with a compact box where the drill bits are not used. You do not need to worry about the absence of any of them. Wide application: The core extractor ensures a clean and accurate hole on the hardest and most abrasive materials such as tiles, granite, marble, other stones and porcelain.
