• Borden coupler: The Borden style coupling is a widely used connection mechanism, distinguished by its two or three distinctive holes. These openings serve specific functions: a larger hole channels air for turbine rotation, while a smaller hole manages water flow. This design ensures efficient cooling and smooth operation. Borden couplers lack an air exhaust, directing air directly out of the handpiece.
  • Midwest coupler: The Midwest style coupling has versatility with two or more larger holes. One hole is dedicated to air intake, while another serves as the air exhaust. Additional holes often accommodate water spray and fibre optics for enhanced illumination during procedures.
  • Six pin couplers: Emerging on the scene, new style couplers equipped with six pins provide a contemporary connection solution. These advanced couplers ensure compatibility with handpieces featuring a six-pin connection design.
