Promed Tungsten Carbide Bit, cone (198421) – for artificial nails
The Promed Tungsten Carbide Bit in a cone shape is a robust bit made of tungsten carbide with teeth for powerful removal and shortening of artificial nails, gel and acrylic. The cone shape reaches edges, corners and hard-to-access areas well. Tungsten carbide removes material quickly and efficiently and runs at a higher speed than sapphire or diamond. Fits all Promed nail drills with a 2.35 mm collet.
