"Drill down" is a phrase used when you want to examine something more closely or in detail. It's often used in computer programs or data analysis when you want to focus in on a specific piece of information. For example, if you are looking at a chart of sales data and want to see which products sold the most, you would "drill down" into that data to get more specific information about those products. Essentially, it means to dig deeper and uncover more details.
