Compare the handpiece's usable speed range, weight and balance, vibration, bit-shank fit, controls, service support and dust collection. KUPA lists the MANIPro 2.0 at a maximum of 30,000 RPM; that is one model's published ceiling, not a target or a measure of performance under load.
A nail e-file combines a control unit and a handpiece. Choose it for the services you perform and the way the controls fit your hand, not just the largest number on the box.
KUPA lists the MANIPro 2.0 at up to 30,000 RPM. Compare the exact maker specifications; a maximum RPM does not state how the handpiece behaves under load.
What to compare
| Specification | What to check |
|---|---|
| Speed range and controls | Whether the unit offers the range and control used in your services |
| Torque | The maker’s published rating and how it defines that specification |
| Handpiece weight and balance | Fit with your grip and work posture |
| Vibration and heat | Exact model notes and care instructions |
| Direction and foot control | How you switch direction and control the unit |
| Shank and collet | Confirm the bit diameter and lock type match the handpiece |
| Warranty and service | Replacement parts, repair route and coverage terms |
KUPA identifies its MANIPro bits as 3/32 inch. Confirm the collet specification on your handpiece before buying bits; shank size is a fit check, not a guide to the bit’s intended use.
Compare carbide and diamond nail drill bits by maker-labeled use, shape and grit. Follow the manufacturer’s maintenance directions and your state board’s tool rules.
Dust and maintenance
Check whether the station needs a separate dust collector and how its filter is serviced. For reusable bits, clean and disinfect according to the bit maker’s instructions and the applicable board rules.
For lamp and gel-system compatibility, see LED vs UV nail lamps. Browse nails, lash and wax.
Common questions
How many RPM does a nail drill need?
Check the exact handpiece specification and the speed control used in your services. A maximum RPM alone does not describe how it performs under load.
What is torque on a nail drill?
Torque is rotational force. Compare a maker-published rating only when the maker explains what that figure describes.
Which nail drill bits should I start with?
Choose bits for the service, material and surface. Check the bit maker's intended use, grit and training guidance before adding it to your kit.
Can a nail drill damage natural nails?
An unsuitable bit or technique can damage the nail. Follow the bit maker's instructions and use appropriate professional training.
