Overview: Heavy-Duty Power, Featherweight Handling

Stop fighting with heavy tools. The Lematec LE-IW1330 redefines what a 1-inch impact wrench can be. By utilizing advanced Magnesium Alloy construction, we have engineered a tool that weighs just 3.7 kg (8.14 lbs)—half the weight of conventional aluminum models—while delivering a staggering 2,600 ft-lb (3,526 Nm) of Nut-Busting Torque. Designed for professional truck technicians and heavy equipment operators, it offers the perfect power-to-weight ratio for continuous use without fatigue.

The Magnesium Advantage: Why Material Matters

Key Difference: Magnesium alloy construction delivers lighter handling, better vibration control, and long-term durability for professional heavy-duty work.

🏆 Magnesium Alloy (LE-IW1330)

  • Lighter Weight: Significantly reduces wrist strain.
  • Higher Stiffness: Better power transmission.
  • Vibration Damping: Protects user from long-term injury.
  • Corrosion Resistance: Built for harsh environments.

⚠️ Conventional Aluminum

  • Heavier: Causes rapid operator fatigue.
  • Less Absorption: More vibration transferred to the hand.
