Answer
A left-hand offset toolholder is used for turning on the backside of the workpiece.
Solution
A left‐hand offset toolholder is arranged so that its cutting edge is offset to the left relative to the tool’s mounting face. This configuration is specifically used when machining the backside of a workpiece—that is, when you’re turning on the side opposite the conventional (headstock) side. In these situations, a standard tool might not clear or achieve the proper geometry. By mounting the tool in a left‐hand offset orientation, you ensure that the cutting edge is correctly positioned for turning on the backside of the workpiece.
So, the correct answer is:
Turning on the backside of the workpiece.

Simplify this solution Beyond the Answer
A left-hand offset standard toolholder is primarily designed to facilitate turning operations that occur from the tailstock to the headstock. This unique orientation allows for improved cutting angles, ensuring smoother and more efficient machining when approaching the workpiece from this direction. In practice, using a left-hand offset toolholder can significantly enhance productivity in operations like finishing or detail work, as it can help minimize chatter and improve surface finish. However, it's essential to double-check the setup before starting to avoid any mishaps that could stem from improper alignment or tool choice!
