What's the difference between carbide, ceramic, and diamond drill bits?

Carbide cuts through acrylic and hard gel quickly, produces chips not dust, lasts 3–6 months — workhorse for bulk removal. Ceramic runs cooler, gentler on natural nails, lasts 1–3 months — best for gel polish removal. Diamond is the only material safe on natural nail and skin — used for cuticle prep, detail work, Russian manicure technique. Lasts 2–4 months.

Which drill bits should a beginner buy first?

Start with a basic 4-bit kit: a coarse carbide barrel for product removal, a fine ceramic barrel for surface smoothing, a small ball or flame diamond for cuticle work, and a mandrel for sanding bands. From this core set you can build up to 8–12 bits as your service menu expands.

Are these drill bits universal?

Yes. Every bit in this catalog uses the standard 3/32" (2.35mm) shank compatible with every pro e-file — Kupa, Kiara Sky Beyond Pro, Mediziel, SunOne, Medicool, and most other major brands.

What grit sanding bands do I need?

80 grit for heavy acrylic and hard gel removal. 100 grit for general shaping and de-bulking. 180 grit for surface smoothing and gel polish prep. Most salons stock all three. Sanding bands are single-use — discard after each client.

Can drill bits be sterilized?

Carbide bits are autoclave-safe and survive repeated sterilization cycles. Diamond bits can be cleaned with a brass wire brush and Barbicide. Ceramic bits are more fragile — clean with brass brush, avoid autoclave if possible to extend lifespan. Sanding bands are single-use and discarded.

Nail Drill Bits & Sanding Bands | Carbide, Diamond & Ceramic Bits

Nail Drill Bits & Sanding Bands covers the full e-file bit catalog at DTK Nail Supply — carbide bits for bulk acrylic and hard gel removal, ceramic bits for cool gel polish work, diamond bits for cuticle prep and natural nail detail, plus disposable sanding bands in 80, 100, and 180 grit on mandrel bits. All bits use the standard 3/32" (2.35mm) shank compatible with every pro e-file in the DTK catalog.

Material choice matters. Carbide bits cut through acrylic and hard gel quickly, produce chips rather than dust (cleaner workspace), and survive autoclave sterilization — but generate more heat than ceramic. Lifespan: 3–6 months with daily Pro use. Ceramic bits run cooler and are gentler on natural nails, making them the preferred choice for gel polish removal — but they're more fragile and last 1–3 months. Diamond bits are the only material safe for direct contact with natural nail and skin — used for cuticle work, dead-skin exfoliation (Russian manicure technique), and detail smoothing. Lifespan: 2–4 months.

Sanding bands are single-use consumables — disposed of after each client to prevent cross-contamination. DTK stocks bulk sanding bands in 100-count and 500-count packs for high-volume salons. Wholesale to US salons. Free ship $100+.
