Diamond Drill Bit 20-68MM Hole Saw Core Drill Bits Cutting Tool Kit for Tile/Ceramic/Marble/Porcelain Cutting | EU

Robust construction: The cutting blade of the diamond hole saw is made of a premium diamond that provides more efficient performance than traditional carbide or bimetal hole saws.
Easy installation: The diamond drill bits for ceramics should be connected to an angle grinder. Drill a pilot hole to start drilling to prevent the saw from wandering from the desired hole.
High Performance: The ceramic pot drill bits have holes on the body to ensure that felt can be removed effectively while the blades rotate at high speed.
Nice Portable Case: The 8-piece diamond core bits come with a compact case where the bits are not in use. You don't have to worry about them being missing.
Wide Use: The core extractor ensures a clean and precise hole on most rigid and abrasive materials such as tile, granite, marble, other stone and porcelain.
