Milwaukee 3-Piece SHOCKWAVE Impact Duty 3/8" Drive Extension Set 49-66-6714

UNYIELDING ACCESS FOR HIGH-TORQUE APPLICATIONS

When your fleet's productivity hinges on reaching recessed fasteners without sacrificing torque transfer, the Milwaukee 49-66-6714 3-Piece SHOCKWAVE Impact Duty™ Extension Set is the definitive mechanical solution. Engineered from forged impact-grade steel, these extensions are designed to withstand the violent rotational forces and repetitive anvil strikes of 3/8" cordless impact wrenches, ensuring that kinetic energy is delivered directly to the fastener rather than being dissipated through accessory flex. For shop managers looking to maximize tool utility and reduce downtime from fractured equipment, this set offers the fatigue-resistant construction required for heavy-duty industrial environments and high-cycle maintenance schedules.

• / SHOCKWAVE IMPACT DUTY™ GEOMETRY: Optimized for the high-torque output of modern cordless impact tools, reducing torsional stress on the drive end.
• / FORGED IMPACT STEEL: Provides the structural integrity and surface hardness needed for high-cycle use with professional 3/8" drive tools.
• / DUAL-HOLE RETENTION DESIGN: Features a dedicated ring groove for secure attachment to friction ring or pin-detent anvils, preventing hazardous accessory drops.
• / LASER-ETCHED MARKINGS: High-visibility size and length identification ensures technicians pull the correct extension from the drawer the first time, every time.
• / ASME COMPLIANT: Rigorously tested to meet and exceed industry-standard safety and performance specifications for impact-rated hand tools.
