nail file grit guide

One of the most important nail tool for your average nail technician is the nail file. Nail files all have different grit sizes that varies from 60 to 240. Each number represents the amount of grit on a file. Every grit size has different uses of the file.For example:A file with 100/100 will have 100 grit on both sides. However, 80/100 grit will have 80 grit on one side and 100 grit on the other. So, the side with 80 grit is going to be coarser than the side with 100 grit.

60 grit is the sharpest file carries. 60 grit files are coarse enough to file away the excess dead skin on or calluses on one's foot. This coarse grit is not advised to be used for natural nails.

100 grit is the most common file to use when shaping and shortening acrylic nails. Although it is best to use on acrylic nails, 100 grit files may be used on natural nails (depending on the nails thickness).

180 grit is the finest grit size carries. It is used to contour and shape nails of medium thickness. 180 grit files are commonly used to shorten and shape natural nails or prepping nails before applying product.

Or have you seen your nail technician using a nail file at the salon and wondered why sometimes it feels heavier and sharper than others?

The answer is simple: it’s because there’s more than one nail file grit. That’s right! Like sandpaper, nail files come in a wide variety of grits for various reasons.

After all, you don’t want to use the same nail file you used to remove your gel polish to shape your natural nails. Why? Read on to find out!

In this article, we’re taking a closer look at nail file grits, what they mean, what they’re for, and how to choose the right kind for you.

If you look closely when you buy a nail file, you’ll notice that most files have a number associated with them. You may have seen some in the past and wondered what these numbers meant.

These numbers are the grit on nail files — the size of the abrasive particles on the file and nail file coarseness.

The lower the grit number, the rougher the grit, while the higher the number, the finer the grit. Knowing a file’s grit can help you determine which file you need for various nail care purposes.

Now that you know what nail file grits are, the next step is understanding that one file doesn’t necessarily have just one grit.

Some files have different grits on each side for various purposes. But some have the same. If both file numbers are the same, like 100/100 grit, this means both sides have the same 100 grit.

On the other hand, if the numbers are different, this means the sides have different grits. A file with the number 120/180 grit means that one side is softer than the other.
