Our take on the Milwaukee M12 FUEL 1/4 in. High Speed Ratchet – 2566-20, Cordless Brushless (Bare Tool)

The 2566-20 is Milwaukee's cordless 1/4-inch ratchet built for speed: its brushless motor spins the anvil fast enough to run nuts and bolts down quickly, then you finish the torque by hand. The head is compact for tight engine bays and under-dash work, and the steel yoke housing and rubber overmold are made to survive shop life. It is a bare tool, so you need an M12 battery and charger you likely already own. Against air ratchets and slower cordless ratchets, it trades ultimate torque for speed and portability; against Milwaukee's own standard-speed M12 ratchet, it is quicker but costs more and gives up some breakaway torque.

What reviewers say

  • 4.6 / 514 ratings

Owners rate it highly, with 4.6 out of 5 from 14 ratings. Technicians praise the speed and compact head for engine and interior work, and several note it has replaced their air ratchet for most jobs. The main complaints are the bare-tool packaging and the need to switch direction at the anvil rather than on the body.

What people mention
  • SpeedPraisedOwners say it runs fasteners down much faster than a hand ratchet and keeps up with air tools.
  • SizePraisedThe compact head is repeatedly called out for reaching tight engine-bay and under-dash spots.
  • BatteryMixedBuyers like the M12 platform but note the tool arrives bare, so a battery and charger are an extra purchase.
  • TorqueMixedReviewers say it is quick but will not break loose tight bolts, so hand torque is still needed.
  • Direction controlCriticisedChanging direction means flipping the anvil rather than pressing a switch, which some find slower.
  • BuildPraisedThe steel housing and rubber grip are described as durable and comfortable in daily shop use.

Questions and answers

Does the 2566-20 come with a battery?
No. It is a bare tool, so you need a separate M12 battery and charger. Any M12 pack works, and the compact 2.0 or 4.0 Ah packs keep it light.
How is it different from Milwaukee's standard M12 ratchet?
The High Speed version spins faster for quicker rundown but has lower maximum torque. The standard M12 ratchet is slower and stronger, better for breaking loose stubborn fasteners.
Can I use it like a normal hand ratchet?
Yes. With the motor off it works as a manual ratchet, so you can break a bolt loose by hand and then let the tool run it out.
What size sockets does it take?
It has a 1/4-inch square anvil, so it uses standard 1/4-inch drive sockets. For heavier work, step up to the 3/8-inch version.
How do I change direction?
You flip the anvil by hand. There is no forward/reverse switch on the body, which is the most common complaint from owners.
Is it good for a home garage?
Yes if you already own M12 batteries. For occasional use, a hand ratchet plus a breaker bar covers most jobs, and this tool earns its place on repeated fasteners.
