1. The chisels our factory manufactured are made by 40CrMo steel to fully ensure products' density and performance.
2. Using advanced CNC machining to make accurate size, and paying special attention to each machining detail, to ensure them being equipped with bushings right.
3. Using advanced heat treatment technology, heating them by sectional type, which makes inside machine part be HRC48, abrasion part be HRC55. Meanwhile ensuring having superior wear-resistance and being not easy to break down.
