NISIMA Diamond Drill Bit P893 M042 is a professional diamond-coated drill bit designed for hardware manicure and pedicure procedures. Featuring a broad 4.2 mm working diameter and an elongated 12 mm working part, it provides efficient surface coverage and controlled processing of larger treatment areas.
The blue marking indicates medium abrasiveness, making this version more active than the fine red P893 F042. It is suitable for procedures where stronger abrasive action is required while maintaining controlled, professional e-file performance.
The 4.2 mm diameter provides significantly greater surface contact than narrow precision drill bits, allowing broader areas to be processed more efficiently.
Applications in Pedicure
The drill bit is particularly useful for professional hardware pedicure procedures, including:
Processing keratinized skin
Smoothing localized rough areas
Refining previously treated skin
Working across broader treatment zones
Processing areas requiring medium abrasiveness
Finishing and refinement during hardware pedicure
How to Use NISIMA Diamond Drill Bit P893 M042
Securely insert the drill bit into a compatible professional e-file handpiece.
Select an appropriate rotation speed according to the procedure and treatment area.
Position the diamond-coated working surface against the area requiring treatment.
Work using smooth and controlled movements without excessive pressure.
Use the broad 4.2 mm working diameter for efficient surface processing.
Take advantage of the elongated 12 mm working part when treating larger areas.
Allow the medium-abrasive diamond coating to perform the work rather than applying heavy pressure.
Keep the rotating drill bit moving continuously to minimize localized friction and heat.
After use, thoroughly clean the drill bit and process it according to appropriate professional disinfection and sterilization protocols.
Professional Tips
Blue indicates medium abrasiveness, making P893 M042 more active than the red P893 F042.
The broad 4.2 mm diameter is useful when greater surface coverage is required.
Use controlled pressure, particularly when working near delicate skin or the natural nail plate.
Keep the rotating attachment moving continuously rather than concentrating on one area.
Choose the red fine P893 F042 when gentler processing or finishing is required.
Use a smaller-diameter drill bit for highly detailed or narrow treatment areas.
Clean debris thoroughly from the diamond-coated surface after each procedure.
Replace the drill bit when its abrasive efficiency noticeably decreases.
