Bauer 1882E-B 20V Cordless Impact Wrench
The Bauer Tools Impact Wrench 1882E-B is built for professionals and serious DIYers who need reliable torque on the job site. This 20V cordless impact wrench delivers 300 ft-lbs of maximum torque and 3,200 impacts per minute, making it ideal for automotive work, equipment maintenance, and heavy assembly tasks.
We designed the 1882E-B with a compact brushless motor that extends runtime and tool life while reducing heat buildup during extended use. The ergonomic grip and balanced weight distribution help reduce fatigue during overhead work or all-day fastening applications. An integrated LED work light illuminates dark engine bays and tight spaces where you need precision.
The variable speed trigger gives you complete control from gentle starts to full power, while the forward/reverse selector allows quick direction changes without repositioning your grip. Our tool-free socket retention system accepts standard ½-inch drive sockets and keeps them secure during high-torque applications.
- 300 ft-lbs maximum torque for tough fastening applications
- 3,200 IPM (impacts per minute) for rapid driving speed
- Brushless motor technology for longer runtime and tool life
- ½-inch square drive anvil with detent pin socket retention
- Integrated LED work light with 20-second delay after trigger release
Brushless motor technology & runtime
The 1882E-B features a high-efficiency brushless motor that eliminates carbon brush friction and wear. This design delivers approximately 30% longer runtime per battery charge compared to traditional brushed motors, allowing you to complete more fastening tasks between charges.
Brushless technology also reduces internal heat generation during sustained use, which protects motor windings and electronic components from thermal damage. Our testing shows the motor maintains consistent torque output even after extended operation, unlike brushed alternatives that experience performance degradation as brushes wear down.
Torque settings & application range
The Bauer 1882E-B delivers 300 ft-lbs of breakaway torque, making it suitable for automotive lug nuts, suspension bolts, and structural fasteners up to ¾-inch diameter. The variable speed trigger allows you to modulate power delivery from 0 to 3,200 impacts per minute based on fastener requirements.
Recommended applications
This impact wrench excels at tire changes, brake service, engine repair, and general equipment maintenance where high torque is essential. The compact 7.2-inch head length provides access to recessed fasteners in engine compartments and undercarriage locations where longer tools cannot fit.
Ergonomics & user comfort features
We engineered the 1882E-B with a rubberized grip that provides secure control even when wearing work gloves. The grip diameter measures 1.8 inches, which fits comfortably in most hand sizes without requiring excessive gripping force during operation.
The tool weighs 3.4 pounds with a 2.0Ah battery installed, creating a balanced weight distribution that reduces wrist strain during overhead fastening. An integrated belt hook on the tool body allows convenient storage when moving between tasks without setting the wrench down.

What people are saying
Common questions about the 1882E-B impact wrench
The 1882E-B features a ½-inch square drive anvil with a detent pin retention system. It accepts all standard ½-inch drive impact-rated sockets, which are the industry standard size for automotive and heavy-duty fastening applications.
We recommend using impact-rated sockets rather than chrome hand-tool sockets, as impact sockets are heat-treated to withstand the repeated striking forces generated by impact wrenches. Regular chrome sockets can crack or shatter under impact loads.
Battery runtime depends on the capacity of your battery pack and the torque demands of your application. With a 4.0Ah battery, you can typically complete 200-250 lug nut removals during automotive wheel service before requiring a recharge.
For lighter-duty fastening tasks that don’t require full torque output, runtime extends significantly. Heavy structural bolts that demand sustained maximum torque will reduce the number of fasteners you can drive per charge. We recommend having a spare charged battery available for all-day professional use.
Yes, the 1882E-B delivers 300 ft-lbs of breakaway torque, which is sufficient for most rusted automotive and equipment fasteners. The impact mechanism applies sudden rotational force that can break through corrosion more effectively than continuous torque from a drill or ratchet.
For severely corroded fasteners, we recommend applying penetrating oil and allowing it to soak before attempting removal. In extreme cases where fasteners are seized beyond the tool’s capacity, heating the fastener with a torch before impact wrench application often provides the additional help needed for removal.
Yes, we designed the 1882E-B for professional tradespeople who need reliable performance in demanding work environments. The brushless motor provides the durability and runtime required for all-day use, and the three-year warranty covers commercial applications.
Many professional mechanics, equipment technicians, and mobile service providers use the 1882E-B as their primary impact wrench. The tool’s compact size and power output make it particularly well-suited for automotive repair shops and maintenance operations where technicians work on multiple vehicles daily.
Impact wrenches like the 1882E-B use a ½-inch square drive designed for sockets and deliver high torque for loosening and tightening nuts and bolts. Impact drivers use a ¼-inch hex chuck for screwdriver bits and are optimized for driving screws and smaller fasteners.
Impact wrenches generate significantly more torque than impact drivers—the 1882E-B produces 300 ft-lbs compared to typical impact driver outputs of 100-150 ft-lbs. If you primarily work on automotive fasteners, equipment bolts, or structural connections, an impact wrench is the correct tool choice.
No, the Bauer 1882E-B ships as a bare tool without battery or charger included. This pricing approach allows you to use batteries and chargers you already own from our 20V cordless platform, avoiding duplicate purchases if you have other Bauer 20V tools.
If this is your first Bauer 20V tool, we offer combo kits that include the impact wrench with batteries and a charger at a discounted bundle price. You can also purchase batteries and chargers separately to build the power system configuration that matches your specific needs.
Impact wrenches are designed for rapid fastener installation and removal, but they don’t provide precise torque control for final tightening. For critical applications requiring specific torque values—such as cylinder head bolts, wheel lug nuts, or structural connections—you should use a calibrated torque wrench for the final tightening stage.
Many professional technicians use the 1882E-B to quickly run fasteners down until snug, then switch to a torque wrench to apply the manufacturer-specified torque value. This workflow combines the speed advantage of an impact wrench with the precision required for proper assembly.
