Vearter 5PCS/Set M14 Thread Vacuum Brazed Diamond Core Drill Bit, Dia.25/35/40/50/68mm Angle Grinder Hole Saw For Marble Tile Ceramic Granite Concrete

• 5PCS/25/35/40/50/68mm Robust and durable material: the cutting blades of diamond hole saws are made of high quality diamond, providing more efficient performance than traditional carbide or bi-metal hole saws.
• Easy to mount. Diamond drill bits for ceramics should be mounted on an angle grinder. A pilot hole should be drilled at the beginning of the drilling process so that the saw does not deviate from the desired hole position.
• High performance: The ceramic drill bits for pots and pans have holes in the housing to ensure effective chip evacuation when the blade is rotating at high speed.
• The diamond drill comes with a compact carrying case for when the drill is not in use. You don’t have to worry about missing any of them.
• Wide range of applications. The bits produce clean and precise holes in the hardest and most abrasive materials, such as tiles, granite, marble, other stones and porcelain.
