Nail-tech hardware and equipment

Know which nail equipment fits your work before you compare models

E-files, bits, dust collectors and lamps explained from maker documentation and published research: what each one does, what physically and electrically fits, and what the spec sheet leaves out.

What to decide first

  1. Fit first

    Buy bits in the shank size your handpiece maker states, usually 3/32 inch. A 2.35 mm label is not the same number.

  2. 120 V and the right plug

    Choose the US version with an input that covers 120 V, and the maker's own charger or adapter.

  3. Claims kept as claims

    RPM, battery hours, air speed and wavelength are the makers' figures, not measurements. We say so on every page.

  4. Lamps match the gel

    No lamp cures every gel. Use the lamp type your gel maker specifies, and know that LED lamps can emit UVA.

Find your equipment type

Pick an equipment type to see what it does, which specs matter, and what to check before you buy one.

Common buying mistakes

  1. Treating 2.35 mm and 3/32 inch as the same

    3/32 inch is 2.38 mm, and no maker we read says the two labels are interchangeable. Follow your handpiece maker's stated shank size.

  2. Buying the biggest RPM number

    Top speed is a maker figure, not a measurement under load, and Medicool's own guidance has most work well below it. Training matters more than the ceiling.

  3. Expecting a dust collector to replace ventilation

    NIOSH recommends local exhaust at the desk in addition to room ventilation. No collector we found publishes a tested capture figure.

  4. Trusting an "official store" name

    A store name is not proof a brand runs it. Check that the brand's own site links to the seller, and read "Ships from / Sold by" on Amazon.

How we choose

We explain which kind of equipment solves which problem, then what fits: bit shank, 120 V input, chargers and desk space. Every specification is attributed to the maker, a distributor or a named study, and fields no source confirms are marked as not confirmed. We feature a product only when a brand-linked seller and a stated fit are documented. We do not test products, cover gels or chemicals, or promise curing, health or hygiene results.
