What type of cutting tool is used to make heavy cuts and remove metal quickly?

A roughing tool is specifically designed for operations that require the rapid removal of material. These tools are characterized by their robust construction and geometry, which allows them to withstand the stresses and strains associated with heavy cuts. They typically have a larger chip load capability, enabling them to cut aggressively while maximizing productivity by efficiently removing significant amounts of metal in the initial stages of machining.

In contrast, finishing tools are used after roughing to achieve tighter tolerances and a smoother surface finish, prioritizing accuracy and detail over the removal rate. Semi-finishing tools are also designed for material removal but are used in a transitional phase between roughing and finishing. Precision tools focus on high accuracy and are used in applications where dimensional tolerances are crucial, making them ill-suited for heavy cutting scenarios.

Thus, the characteristics and purpose of the roughing tool make it the ideal choice for making heavy cuts and quickly removing metal compared to the other tool types mentioned.
