NISIMA Diamond Drill Bit P893 F042 is a professional diamond-coated drill bit designed for hardware manicure and pedicure procedures. Featuring a relatively broad 4.2 mm working diameter and an elongated 12 mm working part, it provides efficient surface coverage while maintaining controlled abrasive action.
The red marking indicates fine abrasiveness, making the bit suitable for gentle processing and finishing. Its larger working surface is particularly convenient when treating broader areas where a narrow precision bit would require more passes.
