The colour of a nail drill bit indicates its coarseness
The colours of the drill bits are standardised internationally, with yellow indicating an extra fine grit, red indicating a fine grit, blue indicating a medium grit, green indicating a coarse grit, black indicating an extra coarse grit, yellow xx coarse, and pink indicating a killer 3x coarse grit.
The colour-coding system is useful for distinguishing between the different grits, especially for those who may struggle to see the small details that differentiate the bits. However, as there are so many variants, it is always best to check the description of the drill bit to be sure of its coarseness.

The colour stripe can also indicate the type of grit. For instance, red usually indicates a fine grit, while blue indicates a medium grit. However, there are many variants and it is always best to check with the manufacturer to see their specific colour code.
The original colour of tungsten carbide bits is also significant, as these bits are sharper than those with a coating. Carbide bits are ideal for removing acrylics and other enhancements, but they are not recommended for use directly on natural nails.

Some brands use colour to indicate whether the bit is fine or coarse. Different colours represent different grits. For example, red is fine grit, and blue is medium grit. However, there are many variants, and it's always best to check the brand's description.
The colour code can be useful for distinguishing between fine and extra-fine grits, especially for those who have difficulty seeing small details. The colour stripes on burrs (used for sanding and filing) can also make them more visually appealing.
