VEVOR diamond core drill bit for dry drilling, diameter 25 mm, drilling depth 241 mm, M16 internal thread, set includes 3 adapters, a center drill, and a hex key for reinforced concrete, bricks, and masonry

Features and Details

High compatibility: The set includes a 25-mm-diameter crown bit, three adapters, and one center drill, ensuring compatibility with most standard drills and hammer drills. It combines versatility and ease of use for a variety of tasks.

Precise positioning: The diamond core bit for dry drilling is equipped with a center drill, so no pilot hole is required. The sharp tip quickly penetrates the material, ensuring faster and more precise positioning without having to switch modes.

Durable and stable construction: Made of high-quality carbon steel with high-precision welding; the core bit has a hardness of 95 HRB. This reduces overheating during high-load or dry drilling, prevents segment breakage, and extends 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 vibration and deflection 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 air conditioning systems, plumbing, stair railings, roads, airports, and various construction projects.

Made of high-quality carbon steel with diamond-tipped teeth, this core drill bit maintains its sharpness while cutting and grinding hard materials, ensuring excellent wear resistance and a long service life.

Our diamond core drill bit for dry drilling comes with three adapters, ensuring easy compatibility with SDS Plus, SDS Max, and 12.7 mm hex shank drill bits. No additional purchases are necessary—one set covers all your drilling needs.

Manufactured using high-precision welding, this concrete core drill bit offers outstanding wear resistance and stability at high temperatures, keeping the diamond teeth firmly secured even under challenging drilling conditions and minimizing loss or detachment for long-term use.

This diamond core bit is easy to use. First, insert the center bit into the adapter, making sure that the angle of the bit aligns with the screw hole in the adapter. Tighten the screws securely. For precise drilling, the center drill must be centered, and the deviation must not exceed 1 mm.

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.
