Which type of tool is commonly used for turning operations?

1. A left-hand tool

2. A right-hand tool

3. A boring tool

4. A threading tool

The correct answer is: A right-hand tool

Turning operations typically involve shaping material by rotating it against a stationary cutting tool. Right-hand cutting tools are designed to cut on the leading edge when viewed from the front, allowing for effective material removal during a right-hand cutting motion, which is the most common approach in lathe machining. Such tools are engineered to engage the workpiece in a way that optimizes cutting efficiency and chip removal. While left-hand tools can also be used in certain scenarios, they are less commonly employed for general turning operations compared to right-hand tools. Boring tools specifically serve the function of enlarging existing holes rather than performing turning operations. Threading tools are specialized for creating screw threads, which involves a specific cutting motion distinct from typical turning tasks. Therefore, the right-hand tool is predominantly preferred for effective turning operations because it allows for smoother cuts and better control during the machining process.
