Milwaukee 49-66-4567 6PC SHOCKWAVE Impact Duty 6" Magnetic Nut Driver Set

The SHOCKWAVE Impact Duty Magnetic Nut Drivers are built with the Most Durable Magnet to stand up to heavy-duty applications over the full life of the nut driver. The magnetic nut driver holds screws securely during setup for unyielding bit engagement. They are made from heat-treated CUSTOM ALLOY76 steel, which controls hardness for extended bit life. The optimized SHOCK ZONE absorbs peak torque and prevents bit breakage. A chamfered edge gives maximum screw-head engagement, while the improved hex geometry provides the best fit and reduces stripping during use. Color-coded bands on the nut drivers help you pick the right diameter. Designed for use with bit holders in impact drivers and drill drivers.
