In-Store Exclusive

This one's worth the trip to the store.

Brands like Weber, Milwaukee, Yeti, and DeWalt restrict where their products can be sold online — and for good reason. In-store buyers get authentic products, full manufacturer warranty, and access to pricing that simply isn't allowed to be advertised on the web.

  • Authorized dealer network · Full manufacturer warranty & support
  • Guaranteed authentic · No counterfeits, no gray-market resellers
  • The brands set these standards · Be wary of sellers who don't follow them

Every order helps keep your local hardware store on the corner.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

Meet the DeWalt 20V MAX XR Cordless High Torque Impact Wrench — a purpose-built solution for automotive, construction, and fleet service pros who demand power, precision, and portability on every job. This is the tool-only version, designed to pair with your existing 20V MAX XR battery system for a seamless, cord-free workflow.

Power and performance you can trust. The 1 in. square drive drives heavy fastereners with confidence, while a robust torque output (800 units as specified) and 1,900 impacts per minute deliver rapid bolt breakaway and efficient fastener driving. The brushless motor aims for higher efficiency and longer life, helping you get more done on a single charge with less heat buildup during demanding tasks.

Designed for real-world tasks, this wrench shines in scenarios where cords get in the way or a traditional pneumatic tool isn’t practical. Think lug-nut removal on trucks and trailers, industrial equipment maintenance, heavy equipment assembly, and rusted or seized fasteners that demand real torque and repeatable performance. The built-in LED work light illuminates dark, tight spaces so you can stay productive from start to finish.

Key features that set it apart

  • 1 in. square drive for compatibility with a wide range of heavy-duty sockets and adapters.
  • Brushless motor for improved efficiency, cooler operation, and extended tool life.
  • 20V MAX XR platform — part of DeWalt’s trusted cordless ecosystem so you can mix and match batteries and chargers with other tools you already own.
  • Forward and reverse switch for quick bolt removal and fast assembly work.
  • LED light to illuminate work surfaces in low-light environments.
  • UL Listed for added safety and reliability on the job site.
  • Tool Only — battery and charger sold separately, giving you the flexibility to upgrade gradually or expand your existing 20V system.
  • Warranty — 3-year limited parts and labor for peace of mind with extended use.

What’s included and how to use it

This listing is for the tool only. You’ll need a compatible 20V MAX XR battery and charger (not included) to power this cordless high-torque wrench. Pair it with a selection of 1 in. sockets and your favorite impact-rated sockets to tackle everything from lug nuts to heavy bolts. Because it’s cordless, you gain mobility across jobsites, auto shops, and field service locations—no cords to manage or trip over.

Who should consider this DeWalt high-torque wrench

  • Professional automotive technicians and tow-truck operators needing rapid bolt breakaway without air hoses.
  • Fleet maintenance crews performing frequent wheel removals, suspension work, or large-bolt installations.
  • Construction pros working on heavy equipment assembly or disassembly where cords aren’t practical.
  • DIY enthusiasts pursuing a capable, professional-grade tool that grows with their 20V MAX XR collection.

Practical tips for best results

  • Use a properly rated 1 in. impact-rated socket to maximize grip and minimize wear on both the fastener and tool.
  • For extended runtimes, pair with a high-capacity 20V MAX XR battery and give the motor brief rests during consecutive heavy tasks.
  • Keep the tool clean and dry to maintain the LED light brightness and overall performance.
  • Always confirm fastener thread engagement and torque requirements before tightening to avoid over-torquing or snap-offs.

Whether you’re upgrading from a corded model or expanding your cordless toolkit, this DeWalt 20V MAX XR High Torque Impact Wrench delivers the rugged capability, efficiency, and reliability professionals rely on — now in a convenient tool-only package that integrates with your existing DeWalt ecosystem.
