What is a Reamer?

A reamer is a tool primarily used in metalworking to enlarge and finish holes with precision. It is typically employed to refine holes that have been drilled to a rough size, achieving specific diameters and surface finishes. The reamer has multiple cutting edges on its inside, which rotate to smooth and enlarge the hole as the tool moves in a circular motion, improving accuracy and finish.

Reamers are particularly valuable when the drilled holes are not perfectly smooth or when dimensional precision is critical. They are commonly used in manufacturing machine parts, preparing holes before assembly, and in mold-making processes. The reamer is indispensable for tasks requiring high precision and a smooth finish.

Application of Reamer

✅Precision Machining of Machine Parts
Reamers are used to refine the size of holes in machine parts, such as shaft bearing holes. After drilling the hole, the reamer is used to accurately adjust the diameter to the desired specifications.
✅Mold Manufacturing
In mold making, reamers are used to create precise holes, especially when working with metal. The accuracy of the internal holes in molds is crucial, and reamers help achieve this level of precision.
✅Engine Part Manufacturing
Reamers are used in the manufacturing of engine parts, such as cylinder heads and crankshafts. These parts require highly accurate hole dimensions, and reamers are ideal for this purpose.
✅Aerospace Component Manufacturing
In the aerospace industry, components need to be extremely precise, and reamers play an important role in creating fine holes. Reamers are commonly used for precise hole-making tasks in aircraft components.
