Key Features of the 911PS Circular Saw
- Diamond-coated cutting surface: Ensures efficient, consistent material removal across all plaster classes.
- Perforated disc design: The perforation prevents clogging by allowing plaster debris to escape, keeping the disc clear during operation.
- Saw teeth along the disc edge: Work in combination with the perforations to maintain a clean cutting path and avoid disc blockage.
- Improved positioning visibility: The perforations provide a better line of sight when positioning the instrument on the model, enhancing accuracy.
Important Usage Note
Due to the serration design of the 911PS for Plaster Model discs, they are strictly intended for right-hand rotation only. Using the disc with left-hand rotation will result in destruction of the disc and/or the plaster model. Always verify the rotation direction of your handpiece before use.
Why Choose the 911PS for Plaster Model?
The 911PS for Plaster Model is manufactured to the highest standards, delivering reliability and precision in every cut. Its specialized geometry makes it one of the most efficient tools available for dental laboratory technicians working with plaster models on a daily basis.
Clinical Use
The 911PS is a dental laboratory instrument: mounted in the straight handpiece (HP) and run with right-hand rotation, it is used to saw plaster models of all classes into segments, for example when making saw-cut models.
Care and Reconditioning
Busch rotary instruments are reusable: clean, disinfect and sterilize them after use according to the manufacturer’s instructions, and replace a bur once it dulls or shows damage. Our Dental Bur Reprocessing & Sterilization Guide walks through the workflow for carbide, diamond and steel instruments.

FAQ
Can the 911PS be used in wet plaster?
The 911PS performs across all plaster classes, though it is particularly efficient in dry plaster conditions.
Why must right-hand rotation be used?
The serrated disc design requires right-hand rotation to function correctly. Left-hand rotation will damage the disc and may destroy the plaster model.
What prevents the disc from becoming blocked?
The combination of perforations and saw teeth along the disc edge allows continuous plaster removal, preventing clogging during use.
