Advantages: The abrasive surface consists of 100% calibrated diamond crystals interspersed with ceramic pearls. Open spaces on the working surface allow airflow, cooling the working area and minimizing the risk of burns. The arrangement of the diamond and pearl particles allows trapped debris to fall away easily during rotation. Pearls sit between the diamond grains, creating artificial porosity. The sharp diamond bits remove cuticle tissue, while the smooth pearls polish the treated area. This saves polishing time and the cost of buying special polishing attachments, reducing treatment time. During rotation, the pearls create a pleasant cooling effect. The bits are suitable for autoclave and dry-heat sterilization. Pearl bits have an additional white marking to distinguish them from other diamond bits. Standard 2,35 mm shank, compatible with most manicure drills. Individually blister-packed to protect against counterfeiting.
