The PRO Impact Mixed Set is a great choice for interior fitters and installers who need reliable screwdriver bits and drill bits. The screwdriver bits feature a torsion zone, which absorbs the torque stress at the bits’ tip, making sure they won’t break. The bits have colour-coded rings indicating the head type and laser markings helping you pick out the bit you need. The EXPERT HEX-9 Multi Construction drill bits have hardwearing cutting edges and carbide tips for additional hardness. Their flutes remove chips efficiently, extending the drill bits' lifetime. The set is housed in a sturdy case and arranged in holders you can use to build your own toolbox.
