What type of edges do cutting tools used in the reaming process typically have?

Reaming involves the use of a tool designed to refine and enlarge existing holes to precise dimensions and improve surface finish. The cutting tools used in this process are typically equipped with straight cutting edges. This design allows for effective removal of material while maintaining the desired hole geometry, ensuring that the tool can accurately hone the hole to the specific size and tolerance required.

Straight cutting edges provide consistent cutting action, which is essential for achieving the necessary clarity and precision in a ream, preventing deviations or inaccuracies. This characteristic distinguishes reaming tools from other types of cutting tools that may use curved or round edges for different machining operations. The focus on straight edges in reaming allows for better control and stability during the operation, which is critical in achieving the tight tolerances often required in engineering and manufacturing.
