Which files are used for fitting square and round openings?

When working on tasks that require fitting square and round openings, using square and round files is essential because of their specific shapes tailored for different types of openings. Square files have a flat, square cross-section that is perfect for enlarging and smoothing square openings, allowing for precise adjustments to dimensions. Round files are designed with a cylindrical shape, making them ideal for rounding edges and enlarging round openings while also providing a smooth finish.

The versatility of square and round files is highly beneficial in various applications, including metalworking and woodworking, where achieving the right fit is crucial. Their shapes enable the user to effectively refine edges and corners, ensuring that components fit together properly. This precision is particularly important in assemblies and installations where alignment and fit dictate the quality and functionality of the final product.

Other options may not be suitable for fitting these specific opening shapes. Flat files, for instance, are better for general smoothing and shaping but are not designed for fitting into square or round openings specifically. Half-round files do have one flat side and one rounded side, which can be useful for some tasks, but they do not provide the same level of specificity for fitting square openings. Double-cut files are designed for rapid material removal and have a more aggressive cutting action, but they aren't
