Imagine you are a dentist in the 1950's and a belt drive handpiece is the standard for treating patients. You go to a dental meeting and check out this “high tech” handpiece you’ve heard about that uses air to power a small turbine in the handpiece head. You try it and are impressed with the control you now 
have! The steadiness! The speed at which you can get the job done!
I started dental school in the late 1970’s and was taught using air turbine handpieces. In 2013, I bought the NSK Ti-Max X Series electric handpiece. Picking up this NSK handpiece gave me the same feeling as that doctor from the 1950’s had the first time he picked up an air driven handpiece. You’ll appreciate what torque is once you use this. It doesn’t slow down like an air rotor. The light intensity and illumination area far exceeds any air turbine I’ve ever used. And…it’s certainly quieter than any air high speed I’ve used.
Negatives? It’s heavier and fatter than air turbines…and certainly costlier. In addition, it’s vital that you use plenty of water spray, since the gears in the head will get hot without proper cooling.
I rarely use air high speeds anymore. I’ve bought extra electric high speed attachments to insure I don’t get caught with all my electric handpieces in sterilization. My sales rep was so convinced I'd buy this, he let me have this NSK system for a free trial period to see how I would like using it. How did I like it? I will never go back to 1950’s technology.

In our 2014 DPS evaluation of the NSK Ti-Max X450, Dr. Joshua Howard praises the “incredible amount of power for such a light handpiece.”
