Drilling Machine One Word /Slotted Drill

In-line drill bit: In-line drill bit. It is suitable for light rock drills to drill rock formations with low hardness, which is convenient for grinding. The in-line series drills have a simple manufacturing process, convenient regrinding, reliable operation, and strong adaptability to rock mass performance. It is often used with light internal combustion, electric, pneumatic, and hydraulic rock drills to drill rock holes with a diameter of less than D50mm in various types of rocks. Due to its low price and other characteristics, it is still the main variety of drill bits used in the drilling of medium and small-diameter rock holes in my country's mining industry. The specifications of the in-line drill bits produced by our factory are 28, 30, 32, 36, 38, 40, 42, 50, 60, etc., which are suitable for mining coal, iron, gold, copper, lead, and zinc mines, etc. Construction of railways, tunnels, railways, highways, etc. 1. Complete specifications and varieties from diameter 20-diameter 30, diameter 32-diameter 43, diameter 45-60, and so on. 2. Reasonable material selection and sophisticated manufacturing, not only focusing on the internal quality of the product but also the surface treatment of the product are very fine. 3. The product structure is reasonable. High, medium, and low-grade products can meet the needs of different customers. The alloy classification is suitable for rocks with different hardness coefficients. Scope of application: It is used with various fully mechanized mining machines, fully mechanized excavators, and continuous mining machines, suitable for coal mining, roadway excavation, etc.
