Wiha’s MaxxTor® Bits are impact rated for power tools and rigorously heat-treated to produce a bit lasting up to 120 times the service life compared to standard bits. Wiha’s specially designed torsion zone absorbs up to 30 times the impact energy compared to standard bits, allowing a maximum torsion flex that goes unmatched. All MaxxTor® Impact Bits have the standard 1/4" hex drive for universal application and are available in 1" and 2" lengths for versatile utility. With MaxxTor® Impact Bits you get the tightest-fit precision-machined driver tips from the company that sets the standard for quality and performance. Wiha’s exact-fit tips eliminate excessive bit-wobble for increased driver accuracy. The result is a highly stable engagement with the screw head and a reduction in fastener cam-out that can lead to injury or damage to finished materials.
