Milwaukee 2457-20 M12 Cordless 3/8″ Lithium-Ion Ratchet (Bare Tool)

Where this cordless ratchet fits

The Milwaukee 2457-20 combines a 3/8-inch square drive with cordless operation. It may be useful for running accessible nuts and bolts where repeated hand-ratchet movement is slow or where an air hose would be inconvenient.

Checks before ordering

• Battery system: This is identified as an M12 lithium-ion bare tool. Confirm that your battery and charger are compatible with the exact 2457-20 model.
• Drive size: Match 3/8-inch-drive sockets to the fasteners you expect to encounter.
• Package contents: Bare-tool listings commonly exclude a battery and charger; verify everything included with the seller.
• Performance: Check the current manufacturer documentation for torque, speed, dimensions and weight if these affect your work.

Use and care

A powered ratchet is primarily useful for turning fasteners efficiently, not automatically for final tightening or loosening heavily seized hardware. Follow the fastener specification and use a calibrated torque wrench when an exact final torque is required. Wear eye protection, use sound sockets in the correct size and keep hands clear of pinch points. Remove the battery before changing sockets, cleaning the tool or addressing a jam.
