VEVOR diamond core drill bit for wet drilling, diameter 76 mm, drilling depth 356 mm, 1-1/4″-7 internal thread, high-precision drill bit for reinforced concrete, brick, and masonry

Features and Details

High compatibility: The 76 mm diameter wet core drill bit features a universal 1-1/4″–7 internal thread, which allows for quick and easy attachment to standard hand-held or drill press drills, offering versatility and ease of use.

Wet drilling: This diamond core bit is designed for wet cutting conditions. It reduces heat buildup, which can affect performance, extends service life, reduces friction, and increases drilling speed for more efficient operation.

Durable and stable construction: Made of high-quality carbon steel with high-precision welding; the core drill has a hardness of 95 HRB. This prevents overheating during heavy-duty drilling, reduces the risk of segment breakage, and improves service life.

High-Performance Drilling: Concrete core bits are equipped with precision-ground teeth that ensure smooth, burr-free edges and fast, precise cuts. The center of the teeth is aligned with the mounting axis, reducing wobble and misalignment at high rotational speeds.

Wide range of applications: Suitable for drilling in reinforced concrete, red brick, concrete, and aerated concrete. Widely used in the installation of HVAC systems, plumbing, stair railings, roads, airports, and various construction projects.

Made of high-quality carbon steel with diamond-coated teeth, this core bit retains its sharpness when cutting and grinding hard materials, ensuring excellent wear resistance and durability.

Our diamond core bit for wet drilling ensures fast cutting in wet conditions, which cools and lubricates the drilling area, reduces wear, extends the drill bit’s service life, and minimizes dust for a cleaner work environment.

Manufactured using high-precision welding, this concrete core drill bit offers outstanding wear resistance and stability at high temperatures, keeping the diamond teeth firmly and securely anchored even under challenging drilling conditions, reducing tooth loss or breakage and ensuring a long service life.

These concrete core bits are easy to install and use, even for beginners. When using them, make sure the drill bit is straight and precisely aligned with the wall of the hole to ensure optimal performance and high-quality results.

The crown drill bit ensures clean and precise holes in hard materials such as red brick, concrete, and aerated concrete blocks. Suitable for all drilling needs in construction and renovation projects.
