Dental High Speed Handpiece Low Speed Handpiece Kit Nsk Style (Ex203c + 2 Pana Max) 4 Holes Push + cartridge

HIgh speeds get the job done in a busy orthodontic practice. I am removing bracket cement not enamel so not sure how they will hold up in a general office. The slow speed DOES NOT grip a bur, I use the slow speed for air-rotor-stripping and it does not hold it, it will only hold a prophy angle. The price made it so I didn't return the package, I just ordered different slow speeds.

I think is no original
