The Duofrez 257.FM.045 diamond bit pairs a long, large flame profile with a dual-grit abrasive design. Standard diamond grit is complemented by finer grit between the grains, helping extend bit life while supporting a controlled, gentle finish. The broad flame shape lifts skin effectively and suits both delicate cuticle work and tougher areas such as calluses and embedded buildup.

• Push, lift and gently release cuticles; remove epithelium before detailed preparation
