Solution:

What should be the relationship between the hardness of a single-point cutting tool and the workpiece for effective cutting?

The hardness of the tool should be equal to the hardness of the workpiece.

The hardness of the tool should be less than the hardness of the workpiece.

The hardness of the tool should be at least 1.5 times greater than the hardness of the workpiece.

None of the above.
