The AMEXORS 1:1 Low-Speed Dental Handpiece Kit provides a complete pneumatic drive solution for routine intraoral and chairside low-speed procedures. By utilizing a universal ISO E-type quick-disconnect coupling on the air motor, clinicians can rapidly interchange the 1:1 contra-angle attachment and the 1:1 straight nosecone depending on the clinical task, while also maintaining compatibility with other E-type attachments in the clinic.
Each component in the 3-piece set serves a distinct clinical function:
Pneumatic Air Motor: Operates at up to 0.30 MPa working pressure with a forward/reverse rotational control ring and an external water spray clip. Available in standard 2-hole or 4-hole dental unit hose connections.
1:1 Contra-Angle Handpiece: Features a push-button chuck that accepts standard Φ2.35 mm latch-type (CA) burs for low-speed cavity finishing, post-space preparation, and prophylaxis cup/brush polishing.
1:1 Straight Nosecone Handpiece: Utilizes a twist-lock chuck mechanism for Φ2.35 mm straight (HP) burs, suited for chairside denture adjustments, temporary crown trimming, and oral surgery bone smoothing.
