Ingersoll grand IQV20 Series W8171/W8191 High-Torque Cordless Impact Wrench | 3/4" & 1" Industrial Heavy-Duty Wrench

The Ingersoll Rand IQV20 Series W8171/W8191 are among the most powerful pistol-grip cordless lithium impact wrenches on the market. Powered by a high-output brushless motor with optimized impact logic, they deliver 2710 Nm breakaway torque and 1765 Nm forward torque, achieving an outstanding torque-to-weight ratio in their class.
Equipped with the IQV® power control system, they support 4 torque level switching to precisely fit different fastening demands. Built with an IP6 protection rating engineered for harsh environments and a durable metal housing, they resist dust, fluid and impact damage. The patented 360° shadowless LED ring light, stepless variable speed trigger and comfortable overmolded grip balance operation efficiency and user comfort.
The full series offers 4 drive anvil options: 3/4" standard, 3/4"-6" extended, 1" standard and 1"-6" extended. Compatible with all Ingersoll Rand IQV20 lithium batteries, they are ideal tools for heavy-duty scenarios such as heavy machinery repair, infrastructure construction, commercial vehicle maintenance and steel structure installation

  •  Brushless High Power with 4-Mode Precision Torque Control

    Powered by a high-power brushless motor with optimized impact logic, it delivers an impressive 2710 Nm breakaway torque and 1765 Nm forward torque, with an outstanding torque-to-weight ratio in its class. The IQV® power control system supports 4 torque level switching, allowing flexible output adjustment according to bolt specifications and working conditions, covering all scenarios from light fastening to heavy-duty loosening with one tool.


  •  IP6 Industrial Protection for Harsh Working Environments

    With an IP6 protection rating engineered for harsh industrial environments, it effectively blocks dust ingress and high-pressure water jets, performing reliably in dusty, humid and oily conditions such as outdoor construction sites, mines and shipyards, maintaining stable and consistent performance even in severe working environments.


  •  4 Drive Anvil Options for Stronger Working Condition Adaptability

    Four drive anvil options are available: 3/4"standard square drive, 3/4"-6"extended square drive, 1" standard square drive and 1"-6" extended square drive. Standard models fit routine operations, while extended models can reach special workstations such as deep holes and recessed positions without extra adapters, greatly improving adaptability and work efficiency in complex working conditions.


  •  360° Shadowless Lighting + Stepless Speed for Efficient & Safe Operation

    Equipped with a patented 360° shadowless LED ring light, it provides full-area shadow-free illumination for dim workstations and tight-space operations. The stepless variable speed trigger enables precise output speed control with smooth start and stop. The comfortable overmolded grip offers a secure, non-slip hold, reducing fatigue during long heavy-duty work shifts and greatly improving operation comfort and safety.


  •  Full Metal Reinforced Housing for Heavy-Duty Durability

    Built with a durable metal housing for higher structural strength, it resists bumps, drops and hard object impacts on industrial sites. The overall structure is validated for heavy-duty working conditions, maintaining stable performance under long-term high-intensity operation with a service life far exceeding standard plastic-body impact wrenches.


  •  IQV20 Universal Lithium Platform for Cordless Operation Freedom

    The full series is compatible with all Ingersoll Rand IQV20 lithium batteries, allowing battery and charger sharing with other tools on the same platform to reduce enterprise inventory costs. The cordless design completely eliminates constraints from air sources, cables and hydraulic power, suitable for outdoor, high-altitude and mobile operation scenarios with flexible and efficient heavy-duty work deployment.
