Adjustable Speed Cordless Grinder

Compact pen-style tool measuring 12.5 x 1.9 cm (4.9 x 0.7 inches), constructed from durable plastic and ceramic components. Offers fully adjustable speed control between 10,000 and 20,000 RPM with reversible rotation (clockwise/counterclockwise) for versatile filing, contouring, and polishing tasks. Driven by a 500 mAh lithium-ion battery charged via USB-C port, delivering more than two hours of uninterrupted cordless operation. Engineered for near-silent performance at under 35 dB. Comes with 12 interchangeable grinding heads — including coarse, medium, fine, and polishing variants — all secured instantly without tools and designed for hand-washing and long-term reuse. Ceramic grinding surfaces minimise friction and heat, supporting gentle yet effective removal of thickened nail layers without pulling or snagging. Rounded head edges further reduce risk of micro-tears or irritation around cuticles and sensitive areas. The built-in safety limiter prevents aggressive grinding, encouraging controlled, even shaping ideal for self-use or shared family devices. Designed for reliable daily or weekly use in home nail care — particularly beneficial for individuals managing onychogryphosis, fungal nail changes, or post-surgical nail recovery. Also supports salon-level finishing of artificial nails and careful trimming of small-to-medium pets’ claws when paired with appropriate attachments and technique.
