Milwaukee SHOCKWAVE Impact Duty 1/2" Magnetic Nut Driver 49-66-4737

ENGINEERED FOR HIGH-TORQUE FASTENING AND MAXIMUM BIT LONGEVITY

When you're driving heavy-duty fasteners with high-torque impact tools, the mechanical stress on your accessories is immense. The Milwaukee SHOCKWAVE Impact Duty 1/2" Magnetic Nut Driver is purpose-built to survive these extreme cycles. Utilizing CUSTOM ALLOY76 steel, this driver undergoes a precision heat-treatment process that balances hardness and ductility, ensuring the bit doesn't shatter under load or wear down prematurely. The integrated SHOCK ZONE geometry is the critical failure-prevention feature, absorbing peak torque spikes that would otherwise snap a standard nut setter at the shank. For professionals managing high-volume installations, the industrial-strength magnet and chamfered internal edges provide a secure, non-slip engagement that virtually eliminates fastener drops and head stripping.

• / Optimized SHOCK ZONE™ geometry absorbs 3X more torque compared to standard impact bits, significantly reducing shank breakage.
• / CUSTOM ALLOY76™ Steel construction provides maximum resistance to wear and shock for up to 30X longer life.
• / High-strength internal magnet is engineered to stay seated over the life of the tool, ensuring consistent fastener retention in all orientations.
• / Precision-machined hex geometry and chamfered edges allow for a superior fit on fastener heads, preventing rounding during high-speed applications.
• / Color-coded identification rings provide quick, at-a-glance size selection in the tool bag or on the jobsite.
