Kin 5-in-1 Medium – PVD Gold Tungsten Carbide Drill Bit

The Kin 5-in-1 Medium is your all-rounder bit, designed for smooth, controlled product removal and refinement at every stage of your service. Featuring a 7.0mm straight groove barrel and a multi-grit design — medium at the base, fine in the middle, and extra-fine at the tip — it’s perfect for balanced bulk removal, shaping, and delicate cuticle detailing without having to switch bits.

Crafted from 100% Tungsten Carbide with a PVD Gold finish, this bit offers exceptional durability and performance. Unlike standard gold plating, PVD (Physical Vapour Deposition) creates a harder, more scratch-resistant surface that withstands heat and daily wear, giving you a longer-lasting, reliable bit for busy salon life.

Key Features

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

• PVD Gold coating – more durable and resistant than standard gold plating

• 7.0mm straight groove barrel for controlled, even breakdown of product

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

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

Ideal For

✔ Balanced removal of builder gel & gel polish
✔ Refining acrylic or hard gel overlays
✔ Controlled bulk reduction and infills
✔ Sidewall shaping & surface smoothing
✔ Gentle cuticle zone work with precision tip

How to Use

Recommended RPM settings:

• Gel polish/hard gel removal: 15,000–25,000 RPM – light side-to-side motion

• Overlay refinement: 12,000–18,000 RPM – smooth, even strokes

• Shaping acrylic: 12,000–20,000 RPM – short passes, minimal pressure

• Cuticle detailing: 5,000–8,000 RPM – use extra-fine tip with care

Pro Tips:
✔ Let the grit do the work — avoid heavy pressure
✔ Keep the bit moving to prevent heat spikes
✔ Use medium base for removal, fine middle for refining, and extra-fine tip for delicate detailing

Safety & Care

⚠ Warnings:

• Do not use directly on natural nails

• Always wear a mask to avoid dust inhalation

• Disinfect thoroughly after every use

Cleaning:

• Brush off dust/debris with a stiff nylon brush

• Sterilise after use

• Autoclave-safe for complete sterilisation

• Store in a clean, dry container

Lifespan:
6–12 months with regular salon use (replace once grooves show wear).

Troubleshooting

• Bit feels too aggressive: Reduce RPM and use fine/extra-fine zones

• Uneven finish: Maintain light, consistent pressure and rotate between grit sections

• Clogging with dust/product: Clear grooves regularly with a brush at the desk
