Sharpened carbide drill bits are inlaid with sharpened alloy that can be sharpened; as the drill drills, the alloy wears and becomes dull, and the drilling speed gradually decreases.
The sharpened carbide drill bit is a carbide cutting tool with an edge angle. During the drilling process, it is continuously blunted by the rock formation and the contact surface increases. The drill bit needs to be re-sharpened when used again. It is mainly used for coring drilling in medium-hard to hard formations, with high footage speed and drilling efficiency.
Sharpened carbide drill bits are mainly composed of drill bit bodies, cutting tools, carbide columns, etc. The cutting tool is embedded in the drill bit body and is firmly connected to the drill bit body through a carbide column. During use, the edge angle of the cutting tool is constantly blunted by the rock formation, resulting in an increase in the contact surface. Therefore, it needs to be sharpened regularly to make it sharp again so that drilling can continue.
Sharpened carbide drill bits are suitable for core drilling in medium-hard to hard formations, and are especially suitable for complex formations with high abrasiveness, water dripping, and crack development. Due to its simple structure and easy operation, it has high footage speed and drilling efficiency. At the same time, because it uses cemented carbide columns as cutting tools, it has good wear resistance and can coring drill multiple times on the same diameter, improving coring efficiency.
Sharpened carbide drill bits need to avoid core clogging during use to ensure core quality. At the same time, in order to extend the service life of the drill bit, regular maintenance is required. The sharpened carbide drill bit is a drill bit suitable for coring drilling in medium-hard to hard formations. It has high footage speed and drilling efficiency, but it needs to pay attention to the problem of core clogging and perform regular maintenance.
