Vacuum Brazed Diamond Core Drill Bit For Porcelain Marble Granite Tile Ceramic
Vacuum brazed diamond core drill bits, designed for drilling large-diameter circular holes in hard and brittle materials such as stone, tiles, and glass. It adopts an advanced vacuum brazing process to firmly weld diamond abrasives onto the steel matrix, forming a sharp cutting edge for efficient and precise dry or wet drilling.
Vacuum brazed diamond core drill bits of different diameters, featuring a uniform golden appearance and a unique serrated cutting edge. The bottom of each drill bit is marked with its specification size (e.g., 25MM, 32MM, 35MM, etc.) and has a standard M14 threaded interface, which can be directly installed on power tools such as angle grinders and electric drills. The evenly distributed diamond particles on the cutting edge, which is the key to its high wear resistance and cutting efficiency.

Key Characteristics
🔹High-Efficiency Cutting: Utilizing vacuum brazing technology, the diamond particles have a strong bond with the matrix, providing sharp cutting, fast drilling speed, and high efficiency.
🔹Dry Operation: Designed specifically for "dry drilling", it does not require additional water cooling, making it particularly suitable for indoor use or places where water is inconvenient, thus reducing on-site contamination.
🔹Durability: Diamond is the hardest substance in nature, endowing the drill bit with extremely strong wear resistance, long service life, and reusability.
🔹Wide Material Compatibility: Designed for high-hardness and high-brittleness materials, such as marble, granite, tiles, glass, and concrete.
🔹Easy Operation: The standard M14 interface allows for easy installation and removal, compatible with mainstream angle grinders and electric drills on the market.
Usage Scenarios
🔹Home Decoration Projects: Drilling holes in marble or tile countertops in kitchens and bathrooms for installing faucets, soap dispensers, drain pipes, etc.
🔹Construction: Drilling holes in wall or floor tiles or stone for running conduit, water pipes, or installing fixtures.
🔹Glass Processing: Drilling circular holes in glass curtain walls, glass partitions, or glass furniture.
🔹Stone Fabrication: Drilling holes in granite, quartz, and other stone slabs for making sinks, cooktops, etc.
🔹Maintenance and Renovation: Drilling holes in existing tile or stone surfaces for wiring modifications or equipment upgrades.
