The Milwaukee 2457-21 is a popular cordless 3/8-inch ratchet kit that is part of the brand's M12 12V Lithium-Ion tool system. It's a go-to tool for mechanics, maintenance professionals, and DIY enthusiasts who need a powerful and compact solution for fastening and unfastening nuts and bolts in tight spaces.
Key Features and Specifications
Powerful Motor: The ratchet is equipped with a 12V motor that delivers up to 35 ft-lbs of torque and a no-load speed of 250 RPM. This provides the power and speed of a pneumatic ratchet without the need for an air hose and compressor.
Compact and Lightweight: At just 10-3/4 inches long and 1.9 lbs (without the battery), it's highly portable and can easily fit into tight spaces like engine bays. The low-profile head (3/4 inch) further enhances its accessibility.
Durable Construction: The tool features a variable-speed metal trigger and reinforced steel housing, making it durable enough to withstand demanding job site conditions.
M12 REDLITHIUM™ Battery: The kit includes an M12 REDLITHIUM™ battery, which is known for its long-lasting power and durability. The on-board fuel gauge on the tool allows you to monitor the battery's charge precisely.
REDLINK™ Intelligence: This technology provides optimized performance and overload protection, ensuring a long life for both the tool and the battery.
Convenience Features: It comes with a built-in LED light to illuminate dark work areas and a variable-speed trigger for greater control.

Intended Use and Performance
This ratchet is not designed for breaking loose heavily torqued or rusted bolts; for those, you should use a manual ratchet or an impact wrench. Its strength lies in its ability to quickly and efficiently run fasteners in and out after they have been initially broken or before they are finally torqued down. Its compact size and cordless convenience make it a time-saver for repetitive tasks.
