Viper 101/301 from Kinetic Instruments, Inc.

VIPER 101, with a speed of 25,000 rpm, fiber optics, water spray, and fitted with the pop-on friction grip head, mimics a high speed except with substantially more control. VIPER 301, with all the same features and operative intent as that of VIPER 101, is a lower speed version. The 6500 rpm capability effectively provides a handpiece with much more torque and also greater tactile feel.
