Overview
The Milwaukee 2658-20 brings two standout attributes to the Impact Wrenches category: 18V cordless operation and a 2.9-pound weight that makes it one of the lightest tools in this batch. For mechanics and DIYers already invested in the Milwaukee M18 platform, the 2658-20 slots in as a highly portable, no-air-hose-needed option for wheel work, brake jobs, and general fastening tasks.
At $158.46 in a tool-only configuration and 4.7 stars from 254 reviews, the Milwaukee 2658-20 has earned strong early satisfaction scores. The 254-review count is modest compared to the Ingersoll air tool veterans in this batch, but the 50 units sold last month and the consistently high rating suggest real buyer confidence. Milwaukee's M18 platform is one of the most widely used cordless ecosystems in the professional trades, which adds practical value for anyone already running M18 batteries across multiple tools.
The 18V platform and 2.9-pound weight are the two facts that separate this tool from the pneumatic options. Where air-powered wrenches require a compressor, hose, and fixed location, the 2658-20 operates untethered. That portability advantage makes it a practical choice for mobile mechanics, field service technicians, or homeowners working in spaces where an air setup is not available.
Pros
- 4.7-star rating tied with the top-rated tools in the batch despite a modest review count
- At 2.9 lbs, one of the lightest impact wrenches in this batch for low-fatigue extended use
- 18V cordless operation eliminates the need for an air compressor or power cord
- Milwaukee M18 platform compatibility means batteries are interchangeable across dozens of tools
- $158.46 is competitive for a brushless 18V cordless impact from a professional-grade brand
Cons
- Tool-only listing: battery and charger not included, adding cost for new M18 platform adopters
- Only 254 reviews, the second-lowest in the Impact Wrenches group, limits long-term reliability data
- Cordless 18V tools generally produce less torque than equivalent-class pneumatic models
