The Star Titan series consists of low speed motors, nose cones, angle adaptors, and angle heads all designed to integrate seemlessly, providing excellent swivel capability for ease of use. The Star Titan series attachments are very autoclave resistant, made of stainless steel in many cases. This series is so popular now that other companies are beginning to manufacture attachments and heads compatible with the patented Star swivel coupling. Very good quality replacement heads are available as well which screw onto the Star Angle Adaptor crown. Look for good quality heads preferably with bearings which ad to handpiece longevity and quiet, vibration free operation.
