Replaceable tip handpieces offer a less expensive way to have several tip styles. While more economical, they require slightly more care and maintenance, and can result in lost time when changing tips. This new model handpiece is an improvement over the old "sliplock" style in that it runs much cooler and the solid, silver brazed tips make better contact electrically in the handpiece. Old and new style tips are not interchangeable in their respective handpieces. Complete with cord and jack plug to fit all Detail Master units.
