- Is the Milwaukee 2559-21 a 3/8-inch or 1/4-inch ratchet?
- It is the 3/8-inch drive M12 cordless ratchet. That makes it the larger of Milwaukee's two standard M12 ratchet sizes and the one that takes common automotive sockets.
- Does it come with a battery and charger?
- Yes. The 2559-21 is a kit, so it includes one M12 battery and a charger along with the tool. Milwaukee also sells bare-tool versions for people who already own M12 packs.
- Can it replace a torque wrench?
- No. It is for running nuts on and off and for breaking them loose. Final tightening to a specified torque still needs a torque wrench.
- How does it compare with Milwaukee's Fuel high-speed ratchet?
- The Fuel high-speed ratchet spins faster and is aimed at production work. This model has a slimmer, lighter feel and is the simpler entry into the M12 ratchet line.
- Will it fit where a hand ratchet won't?
- Often, yes. The powered head needs less swing room than a hand ratchet, which is why owners use it under dashes and on tightly packed engine components.
- What sockets does it use?
- Standard 3/8-inch drive sockets. No adapter is needed for 3/8-inch sockets, and an adapter is required for 1/4-inch or 1/2-inch ones.
- Where is the Milwaukee 2559-21 cheapest?
- At JB Tools, for $366.69, as of our latest check.
