A core bit, a specialised drilling tool, creates cylindrical holes or “cores” in various materials like concrete, masonry, stone, and asphalt. It consists of a hollow, cylindrical tube with diamond-embedded segments at its cutting edge. As the core bit rotates and applies downward pressure, it grinds away the material, creating a clean and precise hole. Core bits are used in construction industries, requiring accurate and efficient hole drilling. With over two decades of manufacturing experience, Syntec designs core bits for light and heavy-duty drilling, offering premium quality laser-welded diamond segments that provide optimal drilling speeds and maximum performance. Wet cutting methods are recommended to increase cutting speed and tool life and eliminate hazardous dust, such as silicosis.
1. HUB/FITTING
The hub also know as fitting serves as the connection point between the core barrel and the drill rig. The hub is crucial in transmitting rotational force from the drill rig to the core barrel for effective drilling.
2. CORE BARREL
The barrel also known as ‘body’ of the core bit is responsible for the width and length of the overall cut. In operation, the segments attached to the bottom of the barrel grind the material while the barrel houses the material within.
3. SEGMENT/BOND:
Segments positioned on the bottom of the barrel they are responsible for the cut; these are a compilation of metals known as ‘bond’ that wear away and release diamond crystals.
4. DIAMOND
Diamonds embedded in the core bits segments are the primary cutting elements. Diamonds’ hardness and abrasive properties make them practical for drilling through various materials—the quality and type of diamonds and segment type influence the cutting speed and performance.
5. WELD
Welding is affixing the segments onto the core barrel. Proper welding is crucial for establishing a secure adhesive between the segments and the core barrel. Most of our segments are laser-welded onto the core bits, forming an exceptionally robust core bit capable of withstanding high temperatures and speed. Furthermore, laser-welded segments are reputed to have a lifespan of approximately 35% longer than that of sintered core bits.
