A right-hand end mill rotates ________ in the spindle and _________ when viewed from the front end (cutting edges).

In the context of milling operations, a right-hand end mill is designed to rotate in a specific manner for effective cutting. When mounted in the spindle, a right-hand end mill rotates clockwise. This direction is standard for most milling applications and is important for proper engagement of the cutting edges with the material being machined.

When viewed from the front end, the cutting edges of a right-hand end mill appear to rotate counterclockwise. This visual perspective is crucial for operators to understand how the cutting tools interact with the workpiece. The orientation affects not only the cutting action but also how chips are removed and how the tool's performance is maximized.

Thus, the correct combination of rotation direction for a right-hand end mill, which is clockwise in the spindle and counterclockwise from the front end, aligns with industry standards for effective milling practices.
