| A font, cross type drill bit has the advantages of simple manufacturing process, convenient grinding, reliable work, strong adaptability on the properties of rock mass. Often with light diesel, electric, pneumatic and hydraulic rock drill, the drilling of D50mm below diameter hole in all kinds of rocks. Because of its cheap price, at present in China is still in the mining industry, in small diameter hole drilling, rock drill bit using the main varieties of cut engineering. My company produces the word bit specifications are: 28, 30, 32, 36, 38, 40, 42, 50, 60, and use of Tianshui, Shenyang pneumatic rock drilling machine, suitable for coal, iron ore, gold, copper, lead and zinc ore mining, railway, tunnel, railway, highway engineering construction. 1, complete specifications From the diameter 20- diameter 30 32- in diameter, the diameter of 43 45-60 diameter, etc.. 2, reasonable material selection, manufacture excellent In strict accordance with the ISO9001 quality management system for quality control, quality not only focus on product, and the product surface treatment of very fine. 3, scientific design, beautiful appearance, unique packaging and very eye-catching traceable markings. 4, reasonable product structure High, medium and low-grade products, to meet the needs of different customers, different hardness alloy classification for coefficient of rock Scope of application: and Tianshui, Shenyang pneumatic rock drill, hydraulic drill carriage supporting the use, is suitable for the coal mine, iron ore, gold, copper, lead and zinc ore mining, railway, tunnel, railway, highway engineering construction Bit size: 28, 30, 32, 36, 38, 40, 42, 64, 76, 89 etc. |
