Final answer:
Single-wheel cutters have a disadvantage in terms of limited depth control, which may impact the accuracy of cuts in precision work. Other options like increased precision, enhanced stability, and quick operation are likely advantages, but not the drawback in question.
Step-by-step explanation:
The disadvantage of single-wheel cutters is primarily related to their limited depth control. Unlike multi-wheel cutting systems or more advanced machinery, single-wheel cutters have less flexibility when it comes to adjusting the depth of the cut. This limitation can affect the precision with which the cut is made, potentially leading to less accurate results in workpieces that require strict tolerances.
Choosing between increased precision, enhanced stability, and quick operation as advantages highlights that the single-wheel cutters typically offer a compromise in the depth control for potential gains in other areas. However, in this context, the focus is on the disadvantage hence the correct answer is A. Limited depth control.
