[0002] A reamer is a rotary tool with one or more teeth for removing a thin layer of metal from the surface of a machined hole. A reamer is a rotary finishing tool with a straight or spiral blade, used for expanding or repairing holes. Reamers usually require higher machining accuracy than drills due to their small cutting volume. They can be operated manually or installed on a drilling machine. Reamers are used to ream holes that have been drilled on workpieces, mainly to improve the machining accuracy of the holes and reduce the roughness of their surface. They are tools used for finishing and semi-finishing holes, and the machining allowance is generally very small. Reamers used to machine cylindrical holes are more commonly used, and reamers used to machine tapered holes are tapered reamers, which are less commonly used. According to usage, there are hand reamers and machine reamers, and machine reamers can be divided into straight shank reamers and tapered shank reamers.
