Thread Button Bits(mining drill bits)

Thread button drill bits(rock drill bits) are made by high quality alloy steel bar and tungsten carbides. Through heat treatment,our drilling tools are tough enough to meet rock drilling demands and have the least loss of energy while drilling the rocks. 


Retract Thread Button Bits is a commonly used type of thread drill bit. It is characterized by the advantages of easy disassembly and maintenance during drilling. It is an upgraded version of the traditional T-shaped thread drill bit. T38 in the Retract Thread Button BitsT38-76 model represents its thread specification, and 76 represents the drill diameter.
Unlike traditional drill bits, Retract Thread Button Bits use a special thread structure that makes removal and installation easier and faster. During the drilling process, the Retract Thread Button Bits can be easily disassembled from the drill pipe, which improves the production efficiency and reduces the labor intensity of the workers.
In addition, Retract Thread Button Bits have compact structure, high processing precision, good chip removal and wear resistance, and are suitable for various types of rock drilling. The material can be selected from special materials such as high-quality alloy steel and tungsten-cobalt. Steel has high physical hardness, wear resistance, and can withstand high-intensity vibration loads. The cutting teeth of the Retract Thread Button Bits also adopt an organized arrangement and a relatively open field, which improves the mining efficiency and working life of the drill bit.
In summary, the Retract Thread Button Bits T38-76 model is a thread drill bit with high efficiency, easy disassembly, excellent wear resistance and high productivity. Because of its practicality and reliability in actual operation, it is widely welcomed by miners and prospectors.
