The device is an air-powered dental handpiece for use by a trained professional in general dentistry.

The Vector F series handpiece shares virtually all specifications and design characteristics of the predicate devices. The only major design or engineering change is the strength of the autochuck mechanism. By increasing the spring strength we have created and even safer version of the KaVo 625CD. By increasing the bur retention strength form 6 lbs (as with the predicate device) to 8 lbs (Vector F series) we have been able to vastly reduce the odds of a bur prematurely ejecting for the handpiece. A few minor changes to the predicate device which do not affect the performance but we feel make the handpiece even safer are as follows: Reduction in the weight of the handpiece to 2 oz.. This reduces operator hand fatigue. Softened the knurling on the handle. This allows dirt, blood and saliva to be more easily removed from the body shell of the handpiece thus allowing better conformity to sterilization procedures. It also provides better tactile sense to the operator while wearing gloves.
