Overview
The M12 2551-22 is a 12 volt cordless impact tool weighing about 2 pounds, spinning up to 3000 RPM with a 16 amp rating. Its compact weight puts it in the category of tools meant for one-handed use in tight spots.
At 2 pounds, the 2551-22 is light enough to run one-handed for extended periods, which matters more in an impact tool than raw torque figures alone. The 12 volt platform trades maximum power for size and weight, so it fits jobs where access matters as much as force. Speed tops out at 3000 RPM per the listing.
- 12 volt battery powered platform
- Speed up to 3000 RPM

Who it's for
Good for users who value a light, compact impact tool for jobs in cramped spaces over one built for maximum torque. Less suited to heavy fastening work better handled by an 18 volt or corded tool.
Strengths and trade-offs
Drawn from this product's published specifications.
- Light at 2 pounds for one-handed use
- Compact 12 volt platform
- 4.8 rating from 776 reviews
- Lower torque ceiling than 18 volt impacts
- Battery capacity not detailed in the listing
Performance notes
The 12 volt platform and 2 pound weight keep the tool maneuverable in tight spots, at a top speed of 3000 RPM per the spec sheet. The 16 amp rating reflects peak draw from the battery system rather than sustained output, and actual runtime depends on the battery paired with it, which is not detailed in the listing.
