Which power tool works well for driving (or loosening) a large number of fasteners? impact drive hammer dril rotary hammer oscillating multi-tool

## Step 1<br />The question is asking us to identify the power tool that is best suited for driving or loosening a large number of fasteners. Fasteners are typically used in construction or home improvement projects, and the tool that is best suited for this task is the one that can deliver high torque.<br /><br />## Step 2<br />Let's examine each of the given options:<br /><br />1. Impact Drive: This tool is known for its high torque and is specifically designed for driving and loosening fasteners. It delivers a strong, sudden rotational force, which makes it ideal for this task.<br /><br />2. Hammer Drill: This tool is primarily used for drilling into hard materials like concrete or masonry. It combines the hammering action with the drilling, which makes it suitable for these types of materials but not specifically for fasteners.<br /><br />3. Rotary Hammer: This tool is similar to the hammer drill but has a more powerful hammering action. It's also more suited for drilling into hard materials rather than driving or loosening fasteners.<br /><br />4. Oscillating Multi-tool: This tool is a versatile tool that can perform a variety of tasks, including cutting, sanding, and scraping. However, it's not specifically designed for driving or loosening fasteners.<br /><br />## Step 3<br />Based on the above analysis, the Impact Drive is the tool that is best suited for driving or loosening a large number of fasteners.
