Overview
The Milwaukee M12 2551-22 combines a 4.8-star rating across 776 reviews with 300 monthly purchases, making it one of the most compelling active sellers in the 12V compact impact driver segment. Running at 3000 RPM with a 16-amp draw in a 2-pound package, it delivers a strong balance of speed and lightweight handling. At $130 as a kit with batteries and charger, it offers substantial value compared to building a kit from separate components.
The 12V platform limits peak torque relative to 18V and 20V competitors, but the 3000 RPM speed spec is competitive within the compact class. Based on specs and verified owner reviews, the M12 2551-22 is most valued for jobs where tool weight and access are more important than maximum fastening power. Electricians, finish carpenters, and HVAC technicians frequently favor compact 12V tools for exactly this reason.
Compared to the DEWALT DCF801B, the other 12V compact in this group, the M12 2551-22 runs at a higher speed of 3000 RPM versus 2850 RPM and includes a kit, though at a higher price of $130 versus $68.95 bare tool. The 776-review count and 300 monthly purchases put it among the top demand signals in the entire batch.
Pros
- 4.8-star rating from 776 reviews places it among the best-rated tools in the category
- 300 units bought last month is one of the strongest demand signals in this batch
- 3000 RPM delivers best-in-class speed for a 12V compact impact driver
- 2-pound weight makes it among the lightest kits available
- Kit includes batteries and charger at a reasonable $130 price
Cons
- 12V platform cannot match 18V or 20V tools for heavy fastener torque
- At $130, it is significantly more expensive than the DEWALT DCF801B bare tool for 12V buyers
- Milwaukee M12 batteries are not compatible with M18 tools, limiting cross-platform flexibility

Performance notes
Battery powered at 12 volts with a 16-amp draw and 3000 RPM output, weighing 2 pounds. The Milwaukee M12 2551-22 is optimized for compact, lightweight applications: overhead electrical, tight cabinet installs, finish work, and jobs where a smaller tool size provides genuine access advantages. The 3000 RPM rating is the highest in the 12V segment represented in this batch.
What buyers say
The 4.8-star average across 776 reviews reflects consistent high satisfaction. Owners regularly highlight the combination of light weight, reliable trigger feel, and the value of the included kit. Common concerns are limited to the inherent torque ceiling of any 12V tool and the platform lock-in to Milwaukee M12 batteries.
