Special Features
【High-performance Drilling】Our diamond core drill bit feature a cobalt content 4.5 times that of standard drill bits (which only contain 10% cobalt). This elevates the hardness of the base material—achieving HRC 70, a hardness level close to that of carbide—while reducing wear, improving heat stability, and ultimately doubling the drill bit's lifespan compared to regular ones.
【Industrial-grade Segment】It enables high-speed cutting of reinforced concrete with a diameter of ≤25mm. Thanks to its robust structure and innovative laser welding technology, blade breakage is effectively prevented during operation.
【Professional Usage Instructions】For optimal service life, continuous water cooling is highly recommended. The water cooling system not only prevents overheating but also reduces dust and noise, extends the tool's service life, and enhances cutting performance.
【Parameters Diameter】4"/102mm; Drilling Depth: 15"/380mm; Thread Type: 1-1/4-7"; Total Length: 17.7"/450mm; Diamond Segment: 24 x 4.8 x 15mm.
【Wide Range of Application】This concrete core drill bit is specially designed for wet drilling in various materials, including concrete, reinforced concrete, exposed aggregate concrete, old concrete, fireclay brick, and masonry. It is particularly suitable for installation work such as air conditioning, piping systems, and range hoods.
