1:1 Direct Drive Handpiece Key Features

  1. Gear Ratio: The 1:1 direct drive means the motor speed directly translates to the bur speed, typically up to 40,000 rpm.
  2. Connection: These handpieces use a standard ISO E-type connection, making them compatible with most electric or air-driven low-speed micromotors.
  3. Bur Compatibility: They are primarily designed for use with CA (contra-angle) burs, which have a diameter of 2.35 mm.
  4. Design: The angled head (contra-angle) improves access and visibility to less accessible areas of the mouth.
  5. Optics/Irrigation: Feature external water/air spray systems for cooling and visibility.
  6. Materials: High-end models often feature durable, scratch-resistant materials like titanium with special coatings.
  7. Maintenance: They are autoclavable (sterilizable) at temperatures up to 135°C (275°F) for hygiene purposes.
