Milwaukee M12 3/8" Cordless Ratchet vs ACDelco G12 Cordless Ratchet Wrench
Buy the Milwaukee 2457-20 if you already own M12 batteries and want the faster, more refined ratchet. It spins at 250 RPM versus 170 RPM for the ACDelco, and owners rate it higher. The ACDelco ARW1209P is the better pick for a first cordless ratchet or a second kit: it ships as a complete set with a battery and charger, and it claims more torque at 45 ft-lbs. Both are brushed 12V tools with 3/8-inch square drives, so expect similar long-term wear.
- Choose the Milwaukee 2457-20 if you are already in the M12 system and want the quicker, more compact ratchet for tight engine bays.
- Choose the ACDelco ARW1209P if you want a ready-to-run kit with battery and charger and slightly more rated torque.
