Which cutting tool is used in shapers and is similar to turning tools of a specific machine?

The correct answer is the planer. In the context of shaping operations, a planer is designed to produce flat surfaces by moving a cutting tool across a workpiece, much like turning tools are used in lathes to shape cylindrical forms. Both planers and shapers utilize similar cutting mechanisms, where the cutting tool is applied against the workpiece to remove material.

Additionally, planers can handle larger workpieces than shapers, allowing them to produce flat surfaces efficiently. The similarity to turning tools lies in the fact that both types of tools involve a linear cutting motion rather than a rotary motion, which is crucial for achieving precise dimensional control in machining operations. This characteristic makes planers distinct yet comparable to lathe operations, establishing their role in shaping operations effectively.
