Which of the following operations can typically be performed by a drill press?

A drill press is primarily designed for creating round holes in a workpiece through the process of drilling, which is its main function. Additionally, it can perform boring, which is used to enlarge existing holes to achieve precise dimensions and ensure better surface finish. Tapping, another operation that can be executed on a drill press, involves creating internal threads in a hole to accommodate screws or bolts.

These capabilities are due to the drill press's ability to securely hold the workpiece in place while the rotating drill bit penetrates the material, allowing for accurate and consistent operations. This versatility in performing drilling, boring, and tapping makes answer B the most fitting choice.

The other options listed, such as turning, welding, and grinding/polishing, are not operations suited for a drill press. Turning is typically performed on a lathe, welding requires specific equipment and techniques, and grinding and polishing are done using grinding machines or polishers. Hence, they do not align with the primary functions of a drill press.
