Description
Concrete core drilling is widely used in construction, renovation, and infrastructure projects to create precise holes in concrete, masonry, and stone structures. Common applications include installing openings for plumbing, electrical wiring, and HVAC systems, creating spaces for doors and windows, extracting concrete cores for quality testing, drilling holes for anchor bolts and fasteners, and making openings for ventilation and drainage systems. Core drilling is highly valued for its precision and its ability to maintain the integrity of surrounding structures.
For fast and accurate core drilling in concrete, a concrete diamond core bit is essential. This particular bit is customized with a 110mm diameter and 450mm length, featuring 9 roof segments and high-frequency welding. It’s designed for drilling through hard concrete, as well as other construction materials like brick, block, and masonry. It is specifically intended for wet drilling.
Concrete diamond core bits are highly customizable, as different customers have varying drilling projects and machines, leading to different requirements. We offer full OEM/ODM services for resellers and concrete drilling contractors, including options for diameter, length, connections, logo printing, paint color, and more, ensuring the perfect diamond core drill bit for your needs.
Welding Types
We offer two welding methods for our diamond core drill bits: high-frequency welding and laser welding. Laser welding provides superior strength, making it ideal for core drill bits used on reinforced concrete, as the segments endure significant force when cutting through rebar. High-frequency welding, on the other hand, is typically used for core drill bits designed for concrete, lightly reinforced concrete, stone, brick, and other construction materials.

3 specifications – concrete diamond core bits
When purchasing concrete diamond core bits, three key specifications need to be confirmed: diameter, length, and connection type. Once these are determined, we can manufacture the perfect tool for your needs.
Diameter
Since the barrel has thickness, there are two diameters: outside and inside. However, when we mention “diameter,” we generally refer to the outside diameter.
Length
A core drill bit consists of three parts: the segments, barrel body, and connection. Each part has a length, but when we refer to the length, we typically mean the length of the barrel body, excluding the connection and segments.
Connection
The connection is another critical specification, as it determines how the core drill bit attaches to your drilling machine. There are various connection types, with threaded connections being the most common, such as 1 1/4″ UNC, G 1/2″, M14, and 5/8″-11.
