DescriptionAfter repeated forging of the air hammer, the grain carbide in the structure is refined, so as to improve the effect of the strong metal red hardness and wear resistance. At high speed, high steel can be used to resist fatigue fracture. Thus it can prolong its service life and finally achieve the goal of saving time and saving energy for customers.Feature- Color: As shown. - Material: High-speed steel. - Size: 15x10x5cm(LxWxH). - This is a set of 11pcs drilling grinder milling cutter carving locator drills wood milling burrs for rotary tools. - After repeated forging of the air hammer, the grain carbide in the structure is refined, so as to improve the effect of the strong metal red hardness and wear resistance. - At high speed, high steel can be used to resist fatigue fracture. - Thus it can prolong its service life and finally achieve the goal of saving time and saving energy for customers.
