Step-by-step explanation:
True. All cutting tools must be held in a holder that fits in the spindle.
The spindle is the rotating component of a machine tool that holds the cutting tool. It provides the necessary motion and power for cutting operations. The cutting tool is inserted into a holder, which is then secured in the spindle.
This is important for several reasons. First, using a holder ensures that the cutting tool is held securely and accurately in the spindle, preventing it from slipping or falling out during operation. Second, the holder provides a connection between the cutting tool and the machine tool, allowing for efficient transfer of power and motion.
