There are three types of rock-breaking tools that are indispensable for drilling when drilling. There are three types of roller drills, diamond drills and scraper drills: ¢ÙThe roller drill is composed of the drill body, tooth claw, cone, bearing, water eye and so on. According to the roller structure, it can be divided into two types: milling tooth type and insert tooth type. According to the bearing structure, it can be divided into sealed (or unsealed) rolling bearing and sealed (or unsealed) sliding bearing. The roller cone bit is suitable for drilling various formations. Most extensive. ¢ÚDiamond drills were initially limited to hard formations, and their varieties and scope of use are expanding. Although the price of the drill is high, it has a long working life. If it is used reasonably, it can achieve good economic results. ¢ÛScraper bit has simple structure, convenient manufacturing, and fast drilling speed in soft formations, but the torque is large when drilling, which easily damages the drilling tools and equipment. In recent years, a new type of cutting bit is being developed, which is embedded with a new type of wear-resistant material of different geometries on the bit base, which can adapt to various lithologic formations and can be drilled at high speeds, and its economic effect is increasingly significant.
