Thunder Zone Impact driver bits with an engineered spiral torsion zone, distribute the applied impact evenly throughout the torsion zone, allowing higher impact loads and greatly extended bit life.​

Among the millions of driver bits produced worldwide each year, only a small percentage reach the high quality standards of Alpha. Features include Premium quality S2 raw material, precision head manufacturing, full body hardness and magnetism. The result? Alpha driver bits show less wear, have a longer service life, experience less cam-out, and provide overall improved operational and economic benefits.​
