cordless drill -- portable drill -- the terms seem to be interchangeable.

A portable drill and a cordless drill are similar, but not exactly the same. Let me explain the differences so you can better understand.

1. Portability: Both types of drills are designed to be portable, meaning you can easily move them around. However, a portable drill can refer to any drill that is not permanently affixed to a workbench or a specific location. This includes both corded and cordless drills. On the other hand, a cordless drill specifically refers to a drill that operates without a cord.

2. Power Source: The main difference between a portable drill and a cordless drill is the power source. A portable drill can be either corded or cordless. A corded drill needs to be plugged into an electrical outlet to operate, providing a continuous power supply. In contrast, a cordless drill is powered by a rechargeable battery, which means it can work without being plugged in.

3. Mobility: Since a cordless drill doesn't need to be plugged into an outlet, it offers greater mobility and flexibility. You can use it in spaces without access to electricity or work more freely without the limitation of a power cord. However, you need to recharge the battery periodically, so it might have a limited run time depending on the battery capacity.

In summary, a portable drill is a general term that encompasses both corded and cordless drills, while a cordless drill specifically refers to a drill that operates without a cord, using a rechargeable battery as its power source.
