Diamond Cool Groove Nail Drill Bits

    Filter

      Cool Groove Nail Drill bits are an extremely innovative addition to e-file manicures. These drill bits feature non-standard cross cuts on the surface of diamond cutters, with a depth of 0.1 mm. These cuts enhance air circulation, preventing overheating of the treated surface and ensuring greater comfort during the manicure process. This leads to faster and cleaner manicures.

      Benefits of using Cool Groove Nail Drill bits:

      • Better heat dissipation
      • Sharper than regular diamond bits
      • Longer-lasting compared to regular diamond bits
      • The diamond coating has a hexagonal shape, providing increased durability.
