The Star 430 series led the way in developing lube free ceramic bearing turbines. Made of very tough stainless steel, these handpieces will be around as long as you continue to need them. Turbines develop a lot of torque for this size head, making the Star 430 excellent for a wide range of uses. These handpieces have been around for a long time, making tons available on the reconditioned market. The Star 430 would be a very good choice for new dentists setting up practice, and wishing to forgo the cost of purchasing all new handpieces.
