About this item
Precision Engineered Design: Our core drill bit is designed with universal 5/8"-11 thread, making it easy to quickly assemble onto standard core drilling equipment or handheld drill machines, providing versatility and convenience.
Dual-Use Wet and Dry: Our diamond core drill bit is suitable for both dry and wet cutting conditions. Dry cutting provides faster speeds, while wet cutting reduces dust, catering to various project needs. It's simple to operate with high flexibility.
Wide Applications: Our wet/dry drill core bit is ideal for drilling into hard concrete, bricks, stone, and other tough materials. It is widely used in installations for air conditioning, pipelines, stair railings, highways, airports, and various construction scenarios.
Perfect Kit: Our concrete core drill bit comes with a pilot bit for precise alignment, preventing the drill bit from deviating from the target location. An additional 3.15 in / 80 mm diamond saw blade is included for cutting tasks, eliminating the need for separate purchases.
Stable and Efficient: Our masonry core drill bit is crafted with high-quality carbon steel components and a diamond-grit head, ensuring it boasts excellent wear resistance and an extended lifespan. Laser welding technology ensures no tooth loss or weld detachment, maintaining cutting efficiency.

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.
Worked better then some high end bits I have used. Drilled a 5 in core with no issue or hiccups including 2 -1/2 rebars definitely shocked how good it worked for the price I didn't have the best expectations. But I was wrong
It is well made, ate up the concrete slab using a wet core drill. We went with a handheld model, which works great if you have a lot of experience with large drills.
