How to choose a motor for a rechargeable electric drill / screwdriver:

1. Confirm your motor model is RS550 or motor diameter(about 37.2mm), and motor body length(about 57mm), and total length(about 75.1mm).

2. Confirm the voltage of your motor (DC10.8V-25V) and choose a motor with the same or similar voltage.

3. Confirm the number of teeth of your motor (9-15 teeth), make sure to choose the motor with the same number of teeth, and verify that the outer diameter and thickness of the gears are the same or similar.

Note:

- The RS550 motor has multi voltage and multi gear teeth combinations, which can be adapted to many electric power drills on the market, but there are too many brands and models of power tools, which makes it impossible for us to identify them all, so please compare them carefully before an order.

- If you want to buy RS550 14 teeth motor, there are two sizes of 14 teeth, which are used for different tools, please pay attention to it before order.
