The DARK Sharp Flame Diamond Drill Bit (2.3 x 8 mm) is a high-precision tool featuring an 8 mm working part, making it slightly shorter and more maneuverable for detailed work. The red notch indicates a fine abrasive grit, which is specifically suitable for normal, thin, and sensitive skin. It is ideal for lifting the cuticle, cleaning pterygium from the nail plate, and smoothing out light calluses or small cracks. The bit is made from premium diamond particles that are sieved for uniform shape and size, ensuring a smooth, vibration-free performance. It is resistant to rust and can withstand repeated dry-heat and autoclave sterilization.
