Wet Diamond Core Drill Bit for Granite Marble Stone Premium Quality Wet Use Hole Saw Cutter
Wet Diamond Core Drill Bits, specifically designed for high-precision, large-diameter circular drilling on hard and brittle materials such as granite, marble, stone, and tiles. Featuring a hollow cylindrical structure, it efficiently drills large-diameter circular holes with smooth edges in hard and brittle materials such as granite and marble. It must be used with a continuous water supply for cooling, which not only prevents the drill bit from overheating and burning out but also flushes away stone dust, thereby ensuring high-quality hole walls and extending the tool's service life.

Key Characteristics
🔹 Diamond Segments: High-quality diamond-impregnated rim ensures superior hardness and wear resistance for cutting tough concrete and reinforced materials
🔹Laser Welding: Segments are securely attached to the steel core via laser welding, providing exceptional strength and safety under high loads.
🔹Cooling Holes: The body features multiple circular holes that improve airflow to dissipate heat effectively and reduce noise/vibration.
🔹Turbo Rim Design: The segmented edge allows for rapid slurry removal (chip ejection), preventing clogging and ensuring faster cutting speeds.
Application Scenarios
🔹Stone Fabrication: Drilling holes in marble or granite kitchen countertops, bathroom vanities, floors, or wall panels for installing sinks, faucets, and pipelines.
🔹Tile Installation: Creating holes for water pipes, electrical conduits, and outlet boxes in wall and floor tiles.
🔹Construction: Core sampling (taking core samples) in concrete walls or floors for testing, or drilling holes for installing anchors and pipes.
👉Important Note: Please ensure a continuous water supply for cooling during drilling. Never dry drill, as this will rapidly damage the drill bit and may cause safety hazards.
