Kim 5-in-1 Coarse – PVD Gold Tungsten Carbide Drill Bit

The Kim 5-in-1 Coarse is the ultimate multi-tasking bit, designed to handle every stage of product removal and refinement with ease. Featuring a 7.0mm straight groove barrel and a unique multi-grit design — coarse at the base, medium in the middle, and fine at the tip — it allows you to remove bulk, refine overlays, and perfect cuticle detailing without switching bits.

Made from 100% Tungsten Carbide and finished with a PVD Gold coating, this bit offers superior durability compared to standard gold plating. PVD (Physical Vapour Deposition) creates a harder, more resistant surface, making the bit longer-lasting, more scratch-resistant, and better able to withstand heat and wear — perfect for busy professionals who need reliability and performance.

Also available in Medium grit.

Key Features

• 5-in-1 multi-grit design – coarse (base), medium (middle), fine (tip)

• PVD Gold coating – tougher and more durable than standard gold, offering improved wear resistance and heat control

• 7.0mm straight groove barrel for efficient product breakdown

• High-grade Tungsten Carbide – sharp, strong, and long-lasting

• Universal fit – 3/32” (2.35mm) shaft fits all standard e-file machines

• Designed for both right- and left-handed techs

Ideal For

✔ Removing hard/builder gel & gel polish
✔ Shaping and refining acrylic enhancements
✔ Bulk product removal & infills
✔ Cleaning sidewalls and refining overlays
✔ Gentle cuticle work & detailing with the fine tip

How to Use

Recommended RPM settings:

• Bulk gel removal: 20,000–30,000 RPM – side-to-side motion

• Acrylic shaping: 15,000–25,000 RPM – short strokes, light pressure

• Edge refining: 10,000–15,000 RPM – use medium/fine section

• Cuticle buffing: 5,000–8,000 RPM – light circular motions with fine tip

Pro Tips:
✔ Keep the bit moving to avoid heat buildup
✔ Tilt at a 15–30° angle for efficient product removal
✔ Use coarse base for thick product, fine tip for detailing

Safety & Care

⚠ Warnings:

• Do not use on natural nails 

• Always wear a mask to avoid inhaling dust (especially with acrylic)

• Disinfect thoroughly after every use

Cleaning:

1. Brush off dust/debris with a stiff nylon brush

2. Sterilise after use

3. Autoclave-safe for full sterilisation

4. Store in a clean, dry case

Lifespan:
6–12 months with daily use (replace when grooves show wear).

Troubleshooting

• Bit gets stuck in thick gel: Reduce speed, lighten pressure, clear debris regularly

• Uneven filing results: Rotate the bit to make use of each grit section
