We have brazed diamond core drill bits. This type of core drill is copper brazed, it can be widely used in drilling concrete, reinforced concrete, and masonry with superior efficiency. The segment sharp is great wall segments. It can be installed on Stand Core Driller and Hand-Held Drillers. Vacuum brazed tools are exceptionally aggressive as the tight bond allows highly exposed diamond grit.
Brazed Diamond Core Drill Bits – High-Speed Drilling for Stone, Concrete & Tile
Brazed diamond core drill bits are professional drilling tools designed for fast, accurate, and clean hole drilling in extremely hard and brittle materials. Manufactured using advanced vacuum brazing technology, industrial diamond particles are permanently bonded to a high-strength steel body, delivering exceptional cutting efficiency, long service life, and stable performance.
Compared with conventional electroplated or sintered core bits, brazed diamond core drill bits provide higher diamond exposure, allowing faster penetration, reduced heat buildup, and smoother hole edges.
Key Features & Advantages
Vacuum Brazed Diamond Technology
Diamonds are metallurgically bonded to the core using high-temperature vacuum brazing
Strong diamond retention prevents premature grit loss
Maintains sharp cutting edges throughout the drilling process
