Grinding a tool bit in a toolholder makes the job easier.

Explanation:
Grinding a tool bit in a toolholder uses the holder as a stable reference, so the tool’s cutting geometry is built against the same surfaces that will seat it in the machine. This keeps the height, rake, and relief consistent with how the tool will actually be used, reducing setup time and the chance of misalignment or chatter. In short, you get a predictable, properly aligned tool more quickly when you grind it while it’s clamped in the holder.
