In machining processes, reamers are often employed after initial drilling or boring operations to achieve tighter tolerances, smoother surface finishes, and improved hole geometries. They are capable of removing small amounts of material from the interior walls of a hole, ensuring that the final dimensions meet exact specifications. Reamers may be operated manually or attached to machine tools such as lathes, milling machines, or drill presses for automated operation. Additionally, specialized reamers, such as taper reamers and counterbore reamers, are used to create specific features like tapered or counterbored holes. With their ability to enhance the accuracy and quality of machined holes, reamers are indispensable tools in the manufacturing and metalworking industries.
