Hardness (Abrasiveness): Red – Soft Blue – Medium Application: Lifting cuticles Treatment of sidewalls Nail plate buffing (alternative to a buffer) Material: High-quality diamond coating that does not heat up and ensures high wear resistance for 3 to 8 months. The spiral arrangement of the teeth allows for much faster treatment of the cuticle or sidewalls. Care for Diamond Bits: Mechanical cleaning after each use with a special brush. Soaking in a special solution for cleaning bits and drills or cleaning in an ultrasonic cleaner. During the disinfection process, adhere to the recommended concentration according to the instructions. Increasing the concentration can damage the coating of the bits. Sterilize in a dry heat sterilizer only when the bits are completely dry, and at a temperature not exceeding 180 degrees Celsius. For professional use only. Store bits in a dry place.
