Drag bits have short blades, each forged to a cutting edge and faced with tungsten carbide tips. Litian is one of the experienced drill bit manufacturers in China and we have many face designs of drill button bits suitable for different rock formations, which can meet the drilling requirements of different hardness rocks, improve drilling efficiency and reduce costs.Īll button drill bits for rock drilling have implemented strict quality control to ensure that each button drill bit is of high quality. Three general types of bits are used when drilling with the LS-100: the drag (blade or fishtail) bit, the roller (or tricone) bit and reamer bits (see Figure 7 ). In actual use, many of our thread button bits, such as R32 button bit, T38 drill bits, T45 drill bits, T51 bits are all have good performance. Its main functions are maintaining the borehole gage, improving drill rods stability and protecting lower part of drill rod from excessive wear. Threads manufactured with precise tolerances enable the drill bit and the drill rod to be connected more tightly, and can transmit impact energy more effectively, while greatly reducing the risk of dents and fractures at the thread end, and improving overall production efficiency. Our drill button bits are with advanced thread manufacturing technology. It is used for cutting softer metals and other low strength materials. High helix drills: This drill has a high helix angle, which improves cutting efficiency but weakens the drill body. Within the general class of twist drills there are a number of drill types made for different kinds of operations. At the same time, it can ensure the verticality of the drilling hole, so that the impact energy can be concentrated on the rock. The twist drill is the most important class. The fixation force is uniform and it is not easy to lose buttons. The drilling rig drill bit adopts advanced button fixation technology. After a special heat treatment process, the drilling rig drill bit has a long service life and can minimize the loss of impact energy during transmission. Our button rock drill bits are made of high-quality steel and cemented carbide as raw materials. What's more, custom design of hard rock drilling bits is supported. We offer different threaded Button Bit Types including standard button bit, retrac button bit, pilot reamer bit, spherical button drill bit, ballistic button bit, flat face drill bit, drop center drill bit etc. Recommended Feeds of Various Diameter Drills Diameter of Drill - Inches, Feed Inches per Revolution Under 1/8, 001 to.
