【HIGH QUALITY】 These diamond drill bits are made of industrial-grade carbon steel and have a nickel-plated coating to resist corrosion. Coated with high-quality diamond, the diamond hole saw creates a smooth, high-precision cut without chipped edges. Reduced drilling speeds, lower drilling pressure, and increased use of water lubrication will significantly extend the life of the drill bit. Drill bit.

【WIDE APPLICATION】 This diamond core drill bit can be used to remove rings from glass, marble, tile, ceramic, PVC, or other materials. When using the diamond core drill bit, please continuously add water to reduce the drilling speed, lower the drilling pressure, and increase the lubricating power of the water, which will significantly extend the drill bit's lifespan.

【ERGONOMIC DESIGN】 Large clearance holes along the drill bit facilitate the entry of cooling water and the evacuation of chips and other particles from the drill hole, ensuring smooth drilling and simplifying the drilling process. Small holes – When debris gets stuck in the core drill bit, we can use our screwdriver to remove it.
