Electric nail file buying guide

Updated: 23 October 2026

You are looking at a row of pens on amazon.co.uk, and the bullets do not agree with each other. One line says rechargeable. The power-source attribute says corded electric. A 35,000 RPM figure looks like a setting you should use, when it is only the top of the dial. This electric nail file buying guide puts the decision in order before you compare brands: the job, the power format, the speed as headroom, the bits, then conflicts and sample size. The [electric file comparison](/hub/hand-tools/electric-file) is the twelve-row table. Peter F. used listings saved on 19 October 2026.

Start with the job, not the brand

The job decides the format, and the brand comes after that. If you are tidying gel polish at the kitchen table, a corded USB pen with a stated 20,000 RPM maximum is the usual home tool in this set. That maximum is headroom. Bulk acrylic, hard gel or a thick builder layer is where reviewers talk about the 30,000 RPM clip-on packs. How those bits differ is on the electric nail file for gel polish removal page. Travel away from a socket is a battery question. The NHS describes pharmacist antifungal treatment over 6–12 months, and a drill is not that treatment.

Three formats and what they cost here

Saved shelf prices fall into three bands. Entry, about £6.99–£9.99, is mostly corded 20,000 RPM pens: the PC120I at £8.29, both C40 lines at £9.98 and £9.99 (4.3 from 14,526, counted once), Ajgvq, PALATALA and KOOFIT. Mid, about £14.99–£33.99, covers the PC90G, the POFIBO and the SC300F. The Scamander, part SC320H, is £69.99. Corded electric plus reviews that the lead must stay in means the pen is not cordless, even when a bullet says rechargeable. That conflict is on both COSLUS C40 listings. Which layout you should buy is on the cordless or corded electric nail file page. Avvchuy, with nine reviews and no RPM, is too thin as a format example.

Speed is headroom, bits do the work

Professional Beauty’s rule of thumb, trade education and not a test of these pens, runs from about 1,000–5,000 RPM for a fine band on the natural nail up to about 15,000–35,000 RPM for bulk gel or acrylic. Use the lower end of the band. A stated 20,000 or 35,000 RPM maximum does not mean you work there. Sanding bands can take off gel polish. A UK review of the COSLUS C40 says acrylic removal failed because no carbide bit was included. Only the PC120I bullet states a 3/32 inch (2.35 mm) shank. The POFIBO bullet lists metal bits and sanding bands, while the included-components field only says 02. Metal is not carbide.

Conflicts, thin samples, and when to stop shopping

Two weights on one page are a conflict. Leave the lighter figure unused when a listing prints two masses. The Scamander’s 900 g is the pack, not the handpiece. The two COSLUS C40 listings share one 14,526-review pool. The Health and Safety Executive says dust from filing artificial nails can cause wheezing, chest tightness and asthma. At home, ventilate. A new drill that is dead or too hot falls under the Consumer Rights Act 2015, section 22, normally 30 days. Do not open the housing. No listing here records UKCA or a BS 1363 plug.

Common questions

What should you decide before you compare electric nail file brands?
Decide the job first: gel-polish tidy, bulk acrylic or hard gel, a session away from a socket, or your own thick toenails. Then read the power-source attribute and check it against UK reviews, because a rechargeable bullet can sit on a corded pen. Treat the stated maximum RPM as headroom and use the lower end of the trade band for that job. Check whether a carbide is actually named. Only then compare brands.
Is a 20,000 RPM pen enough for gel polish at home, or do you need 30,000 RPM?
A stated 20,000 RPM corded pen is the usual home gel-polish tool in this set. Professional Beauty’s medium band for thinner enhancements sits below that maximum, and you should work at the lower end you can control. A 30,000 RPM clip-on is the layout reviewers talk about for bulk product, not a requirement for a thin gel colour. The maximum is headroom on both. Neither figure is a measured working speed.
How do you tell a cordless pen from one that must stay plugged in?
Read the power-source attribute before the marketing bullet. Corded electric, plus reviews that say the lead must stay in, means the pen is not cordless. Both COSLUS C40 listings show that clash. PALATALA’s bullet says it is not rechargeable, which matches a corded attribute. A clip-on can leave the mains and still has a handpiece lead.
Which bits should be in the box for gel polish, and which for thicker gel or acrylic?
Sanding bands and basic bits can remove gel polish if you stay off the natural plate. Bulk acrylic is where a UK COSLUS review failed for lack of a carbide bit. Do not treat unnamed drill bits, or the POFIBO’s metal bits, as carbide. Only the PC120I bullet states a 3/32 inch shank. If the shank is missing, a refill may not fit.
Does a 5 V USB nail drill need a UKCA mark or a BS 1363 plug?
No listing in this folder records UKCA or a BS 1363 plug. PALATALA states 5 V. The Electrical Equipment (Safety) Regulations 2016 apply from 50 V AC or 75 V DC upward, so a 5 V USB pen can sit outside that scope unless a mains adaptor is supplied. That is a scope point, not a certificate.
When should you skip a home drill and see a professional, or return a new unit?
See a professional if you file nails for paying clients, if you have cut or lifted the nail, or if the skin is infected. Do not self-drill if you have diabetes or poor feeling in your feet, or if the skin is hot or swollen. Return a new unit that is dead or too hot under the Consumer Rights Act 2015, section 22, normally within 30 days, and do not open the housing.
