Diamond Cool Groove Nail Drill bits DGF-2.1, shape flame, head size 2.1x8 mm

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.
