Overview
A mechanic loosening a line of bolts gets a brushless cordless ratchet from the ATOMIC line, with a socket end and a brushed yellow nylon body. The tool is listed as ratcheting and as tool only.
Spinning fasteners off by motor saves a lot of time over hand cranking. The listing gives torque but no speed or battery detail, and its voltage entry looks like an error, so confirm the compatible pack.
Who it's for
Brake jobs, suspension work and anything with a long run of tightened bolts reward a powered ratchet. A buyer who does an oil change twice a year can stay with a hand ratchet.
Pros and cons
- Compact ratchet form
- Ratcheting action listed
- Light for its length
- Battery and charger not included
- Voltage entry looks wrong
- Speed not listed
- Not rated non-sparking
Performance notes
A powered ratchet spins the drive until the fastener seats, then the operator finishes with a hand pull, so torque at the end is limited by the tool rating. The battery fitted sets run time, and a brushless motor wastes less energy as heat.

No. The included components list only the DCF512 ratchet, and the name says tool only.
Is the DEWALT DCF512B an impact wrench?
