What are the advantages of reamer?

Reamers are precision cutting tools used to enlarge and finish holes to a specific diameter and smoothness. Their advantages include achieving tight tolerances and improved surface finishes, which are essential for ensuring proper fit and function in mechanical assemblies. Additionally, reamers can increase the efficiency of machining processes by reducing the need for extensive manual finishing. They also minimize the risk of damaging the hole's integrity compared to other methods like drilling.
