This new generation of impact driver technology has embraced the very latest in metallurgy research. The metal composition has been designed to Handle the most demanding impact driving applications, optimum durability and unbeatable break resistance. The Torsion zone has been specifically designed to withstand the sudden rotational and downward forces. Newly developed heat treatment process increases longevity and performance. Bit hardness is Reduced at the body to withstand high loads. In a Black phosphate finish for enhanced corrosion resistance.
