Tool category: a twist drill is classified as which type of cutting tool? Consider the direction of material removal relative to the tool lip edges during drilling. Choose the correct classification.

Q: Tool category: a twist drill is classified as which type of cutting tool? Consider the direction of material removal relative to the tool lip edges during drilling. Choose the correct classification.

Concept In drilling, cutting occurs primarily at the lips at the end of the tool; hence a twist drill is an end cutting tool (though the margins guide along the hole). Final Answer End cutting tool

Difficulty: Easy

Side cutting tool
Front cutting tool
End cutting tool
None of these

Correct Answer: End cutting tool

Explanation:

Concept
In drilling, cutting occurs primarily at the lips at the end of the tool; hence a twist drill is an end cutting tool (though the margins guide along the hole).

Final Answer
