Explain. 

Has a very high wear resistance and impact toughness of the alloy tooth, used in the production of various kinds of DTH Drill, auger, shield cutter, cutting coal tools, mining tools. Widely used in mining, oil exploration, tunnel mining industry. But the different grades of the plate in the strength, toughness and wear resistance of the focus on different. In order to make our products to achieve the best performance of it. Please refer to our grades table (or our engineers recommend) to select the product you want to.
