About this item
Product details
Product Description
KFFKFF Wet/Dry Diamond Core Drill Bit
This specialized diamond core drill bit includes a directional drill and a saw blade. It utilizes high-frequency laser welding technology, providing fast and clean drilling. The 5/8"-11 universal thread makes it an ideal choice for versatile machines used on hard concrete and bricks.
Efficient and Durable Materials
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
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.
Dual-Use Wet and Dry
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.
Easy Operation
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.
Wide Applications
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.
Universal Design
Our diamond core drill is compatible with most types of machines available in the market. You can effortlessly mount the drill bit on your existing equipment.
