Vevor Core Drill Bit, 4" Wet/Dry Diamond Core Drill Bits for Brick and Block, Concrete Core Drill Bit with Pilot Bit Adapter and Saw Blade, 9.5" Drilling Depth, 5/8"-11 Inner Thread, Laser Welding.
Our core drill bit is crafted from high-quality carbon steel with diamond-grit teeth. Diamond is one of the hardest materials on Earth, ensuring outstanding wear resistance. The diamond-grit core drill bit remains sharp and extends its lifespan when cutting and grinding tough materials. Laser welding technology ensures exceptional wear resistance and high-temperature stability for the diamond core drill bit, making it ideal for various drilling conditions, even in high-temperature environments. It's less prone to tooth loss and weld detachment, resulting in increased durability. In dry-cutting mode, you'll experience unmatched cutting and debris removal speeds, boosting work efficiency. In wet-cutting mode, water cooling and lubrication reduce drill bit wear, prolonging its lifespan and minimizing dust. Insert the pilot bit into the adapter, ensuring the drill's tilt angle matches the adapter bolt hole angle, and tighten. Be sure to insert the adapter into the core drill bit and secure it. The pilot bit must be centered on the drill bit, with a center deviation of no more than 1 millimeter. The wet/dry drill core bit ensures clean and precise holes in tough materials like red bricks, concrete, foam bricks, and more. It comes with a diamond saw blade, allowing you to cut various materials with precision, smoothness, and efficiency.
