* Battery Power: Cordless drills are powered by batteries, not directly by a power outlet. The amperage draw depends on the battery's capacity and the drill's motor.
* Variable Usage: The amperage a drill draws varies depending on how much power you're using. Drilling into hard materials requires more power (and amperage) than drilling into soft wood.
* Battery Types: Different battery chemistries (like Ni-Cd, Ni-MH, or Lithium-ion) have different voltage and capacity ratings. This directly affects the amperage draw.
What You Need to Know:
* Battery Amp-Hours (Ah): This indicates the battery's capacity. A higher Ah rating means the battery can deliver more power for longer.
* Voltage (V): The battery's voltage dictates the drill's power. Higher voltage means more power.
* Amperage Draw (A): The actual amperage draw varies depending on the load and the battery's voltage.
To Find the Amperage Draw:
1. Check the Drill's Specifications: Look for the battery's amp-hour rating and voltage in the user manual or online.
2. Consider Load: Understand that the amperage draw will increase when the drill is under heavy load (e.g., drilling into concrete).
Example:
A cordless drill with a 12V, 2Ah battery could draw around 2A under light load. But under heavy load, the amperage draw could be significantly higher, potentially exceeding 5A.
Remember: The actual amperage draw will vary depending on the specific drill model and the load.
