Core Drill Bit Structure
Steel Body: The main structural component is the cylindrical body, typically made of high-strength steel, providing support and the overall shape of the drill bit. In the image, this part is colored blue.
Diamond Segments: The cutting face consists of several individual segments, clearly visible in silver, embedded with diamonds or other hard abrasive materials. These segments are strategically placed to cut through the material.
Diamond Matrix: Within each segment, the small dark points represent the diamonds held in a metallic matrix. This matrix bonds the diamonds and wears away gradually, exposing new cutting edges as drilling progresses.
Waterways (Not Clearly Visible): Although not distinctly visible, the gaps between the segments likely serve as waterways, allowing drilling fluid to flow to the cutting face for cooling and removal of cuttings.
Threaded Connection (Visible in Smallest Bit): The interior of the smallest bit shows threading at the top, which is used to connect the core drill bit to the drill rod or barrel.
