Milwaukee M12 3/8 in Cordless Ratchet 2457-20 - Subcompact Power

In this review the Milwaukee M12 3/8 in Cordless Ratchet (model 2457-20) is assessed as a compact, jobsite-ready ratchet for technicians who need cordless convenience without an air hose. The bottom line: it is best suited to mechanics and maintenance pros who work in tight spaces and value speed and ease of use over maximum torque. The reviewer found the subcompact design, 12V motor and 250 RPM to deliver noticeable time savings on small tasks while offering the build quality expected of a professional hand tool.

Key Features

• Subcompact design: The small head and short body let users reach fasteners in cramped engine bays and other confined spaces.
• 12V motor performance: A powerful M12 motor produces up to 35 ft./lbs. of torque and 250 RPM to replicate the feel and speed of an air ratchet on many tasks.
• Cordless convenience: Being a battery-powered tool removes the need for an air hose, improving mobility and reducing setup time on site.
• Durability for professionals: Built for auto mechanics and maintenance technicians, it stands up to repeated use in workshop environments.
• Body only configuration: Supplied without a battery, it integrates with existing M12 Lithium-Ion batteries for fleets that already use the platform.

Who It's For

This ratchet is ideal for auto mechanics, motorcycle technicians and maintenance professionals who frequently perform small fastener work in tight spaces and already own M12 batteries. It suits users who prioritize tool ergonomics, quick operation and portability over raw torque for the largest fasteners.

Those who regularly remove large, heavily seized bolts or need high continuous torque should look elsewhere for a heavier-duty cordless impact or pneumatic ratchet, since several users note the torque is modest compared with larger drive tools.

Pros & Cons

Pros

• Compact form factor makes access in tight engine bays and assemblies much easier.
• Delivers the feel and speed of an air ratchet at up to 250 RPM, saving time on small jobs.
• Good build quality and value for money, with a professional fit and finish.
• Works with the M12 Lithium-Ion platform, so teams can reuse batteries and chargers.

Cons

• Torque is modest at up to 35 ft./lbs., so it is not the best choice for heavily rusted or very large fasteners.
• Sold as a body only, so users without M12 batteries must purchase a battery separately.

Our Verdict

The Milwaukee M12 3/8 in cordless ratchet is a sensible purchase for technicians who need a compact, reliable tool to speed up small fastener work in confined areas. It offers strong build quality and cordless convenience as good value for money, but buyers should accept its modest torque and plan to use existing M12 batteries or buy them separately.

Frequently Asked Questions

Does this ratchet come with a battery?
No, the 2457-20 is sold as a body only and requires an M12 Lithium-Ion battery purchased separately or from an existing toolkit.

Is the torque enough for automotive work?
For most light automotive tasks and fastener removal in tight spaces the 35 ft./lbs. torque is adequate, but it may struggle with large or heavily corroded bolts.

How does it compare to an air ratchet?
It delivers similar speed and convenience without an air hose, providing the portability of cordless power though with lower peak torque than many pneumatic units.
