What it is

The Milwaukee 2457-20 M12 Cordless Ratchet is a staple tool for automotive technicians and DIY mechanics who frequently find themselves working in cramped quarters. Delivering 35 foot-pounds of torque, this tool is designed to replace manual ratcheting in areas where a standard impact driver simply won't fit. Its low-profile head and slim body profile allow it to reach deep into engine bays or under dashboards without sacrificing control, thanks to the responsive variable speed trigger. Built with durability in mind, the tool features a reinforced steel housing and a recessed forward-reverse switch to prevent accidental changes during heavy use. The integration of Redlink Intelligence protects both the motor and battery from overheating during high-stress applications. While it is not intended for breaking loose rusted suspension bolts, it significantly reduces the fatigue associated with long-winded fastening tasks in professional and home garages alike.

Ravvy AI insight

This tool is a productivity multiplier rather than a torque monster. To maximize its lifespan, users should break tight bolts manually first and then use the M12 motor to spin them out. The M12 platform is highly mature, making this an excellent entry point if you already own Milwaukee batteries, though the 'tool-only' price requires an existing charger setup.

How to get the most out of it

Initial Breaking

Use the tool as a manual wrench to break the initial tension of a bolt before engaging the motor. This saves the internal gears from excessive wear and prevents motor stalling on stuck fasteners.

Ownership tips

tip

Battery Pairing

Pair this with a compact 2.0Ah battery to keep the weight down and the profile slim. Larger XC batteries provide more runtime but can make the tool feel tail-heavy in tight gaps.

care

Cleaning the Head

Wipe down the ratchet head after every use in oily environments. Oil and grit can seep into the variable speed trigger mechanism or the forward-reverse switch, causing sticking over time.

Frequently asked questions

Can this tool remove lug nuts on a car?

No, this ratchet is not designed for high-torque applications like lug nuts. It produces 35 ft-lbs of torque, whereas most lug nuts require over 80 ft-lbs. Use an impact wrench for that specific task.

Does it come with a battery and charger?

This specific model number, 2457-20, is sold as a bare tool only. You will need to purchase a Milwaukee M12 battery and charger separately if you do not already own them.

Can I use this like a regular manual ratchet?

Yes, the internal mechanism is strong enough to allow for manual tightening or loosening. However, avoid putting your full body weight behind it to prevent damaging the motorized drive assembly.

How long does the battery last during a typical job?

With a standard 2.0Ah battery, you can typically expect several hours of intermittent use. Because it is used for spinning fasteners rather than continuous drilling, it is very efficient on the M12 platform.
