2 ) Genuine M2 high speed steel with the black coating ensures durability and sharpness, reduces the friction, runs cooler, performs well in heat, corrosion and rust resistance, for longer cutting edge life even at extreme temperatures.
3 ) The unique 1/2 Square Drive design, suitable for Impact Wrench, 19 size multiple hole stepped up bits, have many steps which contain multiple diameters, convenient to drill different hole size by using a step drill rather than many drills, ideal for DIY projects at home, garden, workshop etc.
