Why is it important to wipe the taper and bore when installing a drill?

To make it shiny
To ensure proper alignment
To increase friction
To decrease wear

The correct answer is: To ensure proper alignment

Wiping the taper and bore when installing a drill is crucial for ensuring proper alignment. When these surfaces are clean and free of debris, it helps achieve a precise fit, which is necessary for the drill to operate efficiently and effectively. Proper alignment minimizes any potential wobbling or misalignment during drilling, which can lead to inaccurate holes or even damage to the workpiece or the tool itself. A well-aligned drill allows for smoother operation and maximizes both the life of the tool and the quality of the work being performed. While keeping the taper and bore clean does not necessarily make them shiny or significantly change friction, it does play a role in reducing wear over time, but alignment is the primary concern during installation. The cleanliness of these surfaces is what ensures that the drill is properly centered and firmly held in place, ultimately contributing to successful machining operations.
