• Surveying

Our company handles diamond construction necessary for building demolition sites, water and sewage systems, river improvement projects, etc., in the diamond division. Using diamond core bits, we primarily perform drilling by rotating while cooling with water to extract cores (test pieces) for seismic diagnosis, and when conducting investigations of structural strength or plumbing work for electricity and gas, we carry out drilling work with diamond cores. [Classification] ■ Diamond core bits are generally classified into single-piece and three-point bits, and also categorized into A lot, C lot, and M27 lot based on the shape of the machine motor part. *For more details, please feel free to contact us.
