What the heck is a Comfort drive XDR 200

What the heck is a 200 XDR?

The 200 XDR is Kavo’s latest entry into the electric high speed market.  This unique handpiece is the same size as the 25LPA or any of the ISO highspeed electrics with one big difference: the motor is built into the handpiece!  That’s right, there is a tiny brushless motor built right into the rear of the contra angle.  This eliminates the need to have a huge, heavy motor hanging off the rear of the handpiece.  This reduces the weight of the handpiece from 13 grams to 5 grams.  The control unit is much simpler too, no front panel or buttons just plug-in the power supply, connect the dental unit and the handpiece and you’re ready to roll.

This is a great simplification over the 25LPA since the 25LPA has eight bearings plus two in the motor for a total of 10 bearings and the 200XDR only has six.  They do this by eliminating the intermediate assembly and running the motor at 188,000 RPMs.

These handpieces are just now getting out of factory warranty and I’ve seen about 10 so far. I’ve been surprised by their performance,  that little motor makes a lot of usable torque, in fact, the XDR seems to be equal to or better  than the 25LPA without the big clunky motor! 

Here is what Kavo has to say about it:

The KaVo COMFORTdrive 200 XDR, operates at only 55 dB, making it the quietest high-speed handpiece on the market today, and features KaVo’s industry-leading chuck strength. The chuck strength delivers exceptional bur concentricity for precise cutting and safety. The bur concentricity and chuck strength further establish KaVo COMFORTdrive 200 XDR as the Dental handpiece for all your high-speed handpiece needs.

KaVo COMFORTdrive’s unique patented design weighs approximately 40% less and is 15% shorter than market-leading high-speed electric handpiece options. The integrated motor reduces the distal length after the pivot point in the doctor’s hand allowing for an unprecedented degree of control.

The KaVo COMFORTdrive system consists of the COMFORTdrive 200 XDR handpiece, the COMFORTtronic control box and the COMFORTbase coupling.

The COMFORTtronic control module features an auto-calibration “ Plug-n-Prep” which allows for air-like “feathering” between 30,000 - 200,000 rpm with the foot pedal. It works off the current air source and no adjustment is required of any other equipment in the office.


KaVo COMFORTdrive 200 XDR works the way you are accustomed to working with air-driven instruments. Therefore, doctors using air-driven handpieces can seamlessly transition to KaVo COMFORTdrive 200 XDR with no learning curve.

Sleek and compact, the COMFORTtronic module neatly incorporates into any operatory, offering an aesthetic, clean look in your dental practice. Simply dedicate the high-speed slot in your dental unit to COMFORTdrive and maintain your existing low-speed option. COMFORTdrive will be available as an integrated option into the Pelton & Crane Spirit 3000 series of delivery units soon.
