All straight shank twist drills must be mounted or held in a _______________.
AI Explanation
The correct answer is C) drill chuck.
All straight shank twist drills must be mounted or held in a drill chuck. This is because a drill chuck provides a secure and accurate method of holding the straight shank of a twist drill, allowing it to be used in a drill press or other power tool. The other options, such as a tapered sleeve (A), morse sleeve (B), or drill socket (D), are not suitable for holding straight shank twist drills, as they are designed for different types of tooling or attachments.
