reaming

Reaming is a precision finishing operation used to enlarge and refine a hole that has already been drilled or bored. The goal is to produce a hole of uniform diameter, good roundness, and a smooth surface finish within tight tolerances. Reaming is typically performed after drilling, boring, or tapping to improve diameter accuracy and surface quality, while removing only small amounts of material.

In metalworking and manufacturing, a reamer is a multi-edge cutting tool that follows the axis of the hole. The operation is performed on a drill press, milling machine, lathe, or dedicated reaming machine, with slow cutting speeds and light feeds to minimize heat and chatter. Reamers can be used with or without lubrication depending on the material and tooling, and they produce highly consistent hole sizes, often specified by standard fits.

Types of reamers include straight-fluted and spiral-fluted variants, as well as hand and machine versions. They come in various materials and sizes to suit steel, aluminum, plastics, and other media. Finishing reaming is common when high concentricity and smooth bore surfaces are required, such as in bearing fits or precision assemblies.

In dentistry, reaming refers to enlarging and shaping the root canal with specialized reamer files to remove tissue and prepare the canal for filling.

In sexual slang, reaming denotes anal penetration, often described as intense or aggressive. The term appears in adult contexts and discussions emphasize consent, safety, and clear communication between all parties involved.
