M4: Speedy

(No. 23000M4-SWFA)

The new addition to our micromotor family convinces with its versatility.

The M4 is optimised for fine, detailed work. For example, grinding, polishing or engraving.
Until now, the options for compact handpieces have been very limited and subject to compromise.
Laboratory turbines and air grinders run on expensive compressed air and have a drop in performance, plus the speed can only be controlled to a limited extent.

Thanks to the compact brushless motor in the handpiece, these problems do not occur with the M4, which is therefore suitable for continuous use.
With a weight of only 95g, it is also the lightest handpiece on the market.
