Description
This concrete hole drill bit has a 32mm diameter and a length of 45mm, featuring crown segments. At Xpert Diamond Tools, crown segments are used for small concrete hole drill bits ranging from 14mm to 50mm in diameter, while bar-type segments are used for concrete hole drill bits with diameters over 32mm.
One of the key advantages of crown segments is their ability to be welded more securely and to match the exact diameter of the barrel, ensuring a perfect fit. In contrast, bar-type segments are available in fixed sizes, which can accommodate a range of barrel diameters but may not provide the same level of precision and alignment as crown segments.
Premium quality concrete hole drill bits ensure smooth and precise drilling. The crown segment system minimizes the risk of segment loss during operation and requires wet drilling.
As a leading manufacturer, Xpert Diamond Tools offers a range of diamond crown core drills, primarily designed for smaller, clean-cut holes, ideal for rebar installation. Our professional diamond crown core bits range from 14mm to 50mm and are suitable for drilling reinforced concrete, hard brick walls, and asphalt. They are widely compatible with angle grinders and drilling machines. Both OEM and ODM services are available.
Welding Types
We offer two welding methods for our diamond core bits for concrete: high-frequency welding and laser welding. Laser welding provides superior strength, making it ideal for core bits used on reinforced concrete, where segments endure heavy stress when cutting through rebar. On the other hand, high-frequency welding is typically used for core bits designed for materials such as concrete, lightly reinforced concrete, stone, brick, and other construction materials.
For more details on the differences between high-frequency welding and laser welding, please refer to our article: 2 Diamond Tools Welding Methods: High-Frequency VS Laser.
3 specifications
When purchasing concrete diamond core bits, it is essential to confirm three key specifications: diameter, length, and connection type. Once these are determined, we can manufacture a tool precisely tailored to your needs.
Diameter
Core bits have two diameters due to the thickness of the barrel: the outside and inside diameters. However, “diameter” typically refers to the outside diameter.
Length
A core drill bit consists of three main parts: the segments, barrel body, and connection. While each part has its own length, “length” generally refers to the barrel body alone, excluding the connection and segments.
Connection
The connection type is another critical specification, as it determines how the core bit attaches to your drilling machine. Threaded connections are the most common, including 1 1/4″ UNC, G 1/2″, M14, and 5/8″-11.
Packaging – concrete hole drill bits
We use specialized packaging methods for our short and long diamond core drill bits to ensure they are well-protected during transit.
For short core bits, we pack them in a durable green hard box with foam cushioning, offering maximum impact protection. For longer core bits, we wrap the body in a protective net to prevent scratches, then place it securely in a white box. This customized packaging guarantees both types of drill bits arrive safely and in pristine condition, ready for use.
