What is a notable feature of reamers?

Reamers are precision cutting tools that are specifically designed to enlarge and finish holes to achieve a desired size and surface finish. A notable feature of reamers is that they typically have multiple cutting edges. This design allows them to engage the workpiece more effectively, resulting in a smoother surface finish and more accurate hole dimensions compared to tools with a single cutting edge. The multiple cutting edges help distribute the cutting force over a larger area, reducing the likelihood of tool damage and improving efficiency during the reaming process.

The presence of these multiple cutting edges also contributes to the ability of reamers to work on materials with various hardness levels, making them versatile tools in manufacturing. This design aspect is crucial for applications requiring tight tolerances and high-quality finishes.
