What grit level does a coarse grit file usually have?

A coarse grit file typically has a grit level of 100 or lower. This level of grit is designed to remove material quickly, making it ideal for shaping and shortening nails. Coarse grit files allow for efficient filing of natural nails or artificial enhancements when more aggressive reshaping is required.

In the context of nail technology, using the appropriate grit file is crucial because it determines the technique and results achieved during a nail service. Coarse grit files are commonly used during the initial stages of the nail shaping process, especially when significant filing is necessary.

Files with a grit level higher than 100, such as those in the 150-180, 180-240, or 240 grit and higher ranges, are considered medium to fine grit. These are more suitable for refining the nail shape and for smoothing the surface of the nails, rather than for heavy-duty shaping.
