Who is it made for?

In most cases, buying tools from a manufacturer as reputable as Milwaukee is usually your best bet. For instance, tools from Ingersoll Rand, Blue Point, Craftsman, and Milwaukee indeed are usually no-brainers. They cover all the bases, producing quality reliable tools, making them suitable for applications that range from amateur users to professional workshops.

However, professional-grade tools like the Milwaukee 2457 cordless ratchet are usually a bit more expensive than other models with similar performance. Of course, you get what you pay for but the higher price tag may be a bit much for auto mechanic apprentices. As a result, only those who will really put this tool to use may justify the price difference.

On the other hand, if you are a professional mechanic and work your cordless ratchet 40 hours a week in the shop, don’t even think twice; this is the one you need!

That being said, I gotta admit I might be a bit biased here. I’m a sucker for Milwaukee’s cordless tool. Heck, I like this ratchet so much that I bought two—one for the shop and one for my home garage.

Features of the Milwaukee 2457-21 3/8 Cordless M12 Ratchet Kit

Milwaukee 2457’s heart is a strong and rugged 12-volt motor that can deliver up to 35 ft-lbs of torque. Having enough power for automotive applications, this battery-powered ratchet will be capable of dealing with even the most demanding tasks.

However, you gotta keep in mind that it’s still just a ratchet and not an impact wrench. Some large and very tight bolts might still require to be started with a breaker bar.

The variable output speed reaching up to 250 RPM is easy to control, thanks to the sensitive trigger. Although some competitors offer models that spin much faster, 250 RPM is still more than sufficient for all car repairs. Of course, this also depends on your preference. Some mechanics like fast tools—I prefer precision.

But to each his own, right?

Fast Charger and Outstanding Battery

The Milwaukee cordless ratchet comes as part of a kit including one battery and a fast charger. The ability to power up dead batteries in only 30 minutes or less will be helpful during extensive usage.

The M12 battery uses an advanced lithium-ion structure to deliver more power, extended life, and faster charging times, ensuring less downtime on the job and boosts productivity.

However, as with any other cordless tool, your best bet is always to have more than one battery if you intend to use it all day. I personally also own the Milwaukee 2457-21 M12 3/8″ Stubby impact and torque wrench and they each came with their own batteries and chargers so I can now use them interchangeably.

That being said, working as a mechanic, it’s not like you’d use your cordless ratchet uninterruptedly for hours. You’ll most likely use it for 5-10 min to remove an oil pan, then another 5-10 min to reinstall it. If you see that the battery starts to get low on the gauge, you can always put it back on the charger between jobs.

Integrated Light for Better Visibility

The Milwaukee 2457 electric ratchet has an integrated LED work light that really helps illuminate the work area. If you ever wrenched before, you know how having a light straight in front of where the bolt needs to go is always a good thing.

Ergonomic Handle and Robust Housing

Both the shape and overall size of the Milwaukee 2457 go in favor of professional and amateur mechanics. It is especially true for the upper part, whose low profile will be a strong point when working in thigh spaces. The shape of the middle section is quite ergonomic, with non-slip padding, providing extra grip, especially useful when the ratchet gets greasy. Moreover, the robust housing is made from strong aluminum alloy, ensuring longevity, and durability.

Weighing slightly over 4.5 lbs, Milwaukee’s cordless ratchet is not among the lightest on the market. It can be a downside in scenarios that include a lot of work in awkward positions, increasing fatigue. Mechanics who will use the electric ratchet extensively should consider this when making the final decision.

FAQs

Yes!

There is more than one feature that makes this device an ideal tool for car repairs. With 35 ft-lbs of torque and up to 250 RPM, it has enough power to undo any bolt or nut.

Does the Milwaukee 2457 Cordless Ratchet come with a battery?

This particular model comes in a kit that, besides the ratchet itself, includes one battery, a fast charger, and a handy carrying case, helping keep everything organized and making transportation easier.

Watch out though. The “Milwaukee 2457-21” moniker is the whole kit. Just know that the ratchet itself is also sold individually, without the battery, and would then be referred to as “Milwaukee 2457” only.
