True. End mills are cutting tools that are commonly used in milling machines to create precise shapes and holes in materials.

Over time, the cutting edges of end mills can become dull or damaged, affecting their performance and accuracy. To restore the sharpness of the cutting edges, end mills are typically sharpened on a machine called a mill grinder. This type of machine uses a rotating grinding wheel to grind away any material on the end mill's cutting edges until they are sharp and precise. Properly sharpened end mills can help to improve the efficiency and accuracy of milling operations, while also extending the lifespan of the cutting tool itself.
