Why Does Your E-File Handpiece Make Noise: Understanding the Possible Reasons

The use of an e-file has revolutionised nail product removal, infills and prep, offering numerous benefits such as faster filing, higher precision, and better control. While using e-file handpieces, you may have noticed that some can produce an unwelcome noise. In this blog post, we will delve into the potential reasons for the peculiar sound emanating from your handpiece.

Friction between the bit and handpiece
The most prevalent source of noise in e-file handpieces is friction between the bit and handpiece. When the handpiece rotates, friction is created between the moving bit and the handpiece housing. Grinding noise or screeching can occur when this friction increases due to several factors, such as improper bit insertion, incorrect bit size, excessive tightening, or bent and damaged bits.

Damaged Handpiece Bearings
A damaged handpiece bearing is another potential cause of noise in your e-file handpiece. Bearings are the tiny metal balls that help to reduce friction between the rotating component and stationary housing. When bearings break due to a knock or drop, they can produce a rattling noise or grinding noise, similar to friction caused by bit mishandling.

Power Supply Problems
Power supply issues can also result in noise from your handpiece. When the voltage is too low (below the handpiece's required voltage), the motor struggles to power the handpiece, resulting in added noise. Conversely, overloading the handpiece with excessive voltage also causes issues, as the handpiece operates beyond its design limits, generating unwanted noise and vibration.

Inadequately Lubricated Bearings
Handpiece bearings require consistent lubrication to function properly and remain in good condition. If the lubrication is inadequate or absent altogether, the friction between the bearings increases, causing them to wear prematurely and produce strange noises.

While the abnormal noise from your e-file handpiece can be a significant distraction, understanding its cause and resolution is crucial. Improper bit insertion, excessive tightening, bent bits, and defective bearings due to damage can increase friction and generate noise in your handpiece. Power supply problems and inadequate lubrication can also cause such noise. It's important to maintain your e-file handpiece regularly and address any issues promptly. By recognising the reasons why your handpiece produces odd noises and taking preventative and curative measures, you can extend the lifespan of your e-file and optimise its performance in your nail care routine.
