This bit is great for refining around the cuticle area when you need to smooth out bulky product. The different sizes allow for different areas to be filed. Larger size is great for those that like to work with a tapered carbide shape. Smaller sizes (come in medium and coarse) can be used around the cuticle area to seal acrylic/gel and also be used for under the free edge of your enhancements.
Standard 3/32" (industry standard) shaft fits most professional grade e-files. Choose from medium or coarse.
