- Core: natural wood — pile length excluding core approx. 15 mm
- Use: acrylic resins & Cr-Co stellites
- Compatibility: standard motors / polishing lathes
- Manufacturing: UTG (Italy)
Advantages of Chungking bristles & 2-row geometry
- Regular absorption of pastes/sandwiches, consistent cutting.
- Maneuverability : access to embrasures, undercuts and edges.
- Controlled finish : less risk of “flat spots” on reliefs.
- Durability : robust structure, controlled wear in everyday use.
Applications in dental prosthesis
- Removal of micro-scratches from preparation.
- Fast polishing with heat control.
- Palate, edges and delicate anatomical areas.
Directions for use
Use a sandpaper or metal paste depending on the material and the finishing step. Work at moderate speed and light pressure in crisscrossing passes to even out the shine. Compatible with most polishing lathes . For tank hygiene, use a sandpaper disinfectant .

FAQ — UTG 60 mm brush (2 rows)
2 rows or 3/4 rows: which to choose?
The 2 rows favor precision: less contact, more control in the fine areas, with a reduced risk of “flats” on the reliefs.
- The 3 rows offer a compromise between efficiency and finesse, useful for medium surfaces with varied geometries.
- The 4 rows maximize the support surface and uniformity over large areas (palate), but require increased vigilance to preserve the edges.
- In summary: 2 rows for precise work and delicate access, 3 rows for versatility, 4 rows for productivity on large surfaces, at adapted speed and pressure.
What pastes/sandwiches and settings do you recommend?
On resin, start with a well-hydrated medium-grain natural pumice to even out the look, then move on to a fine paste to increase the shine.
- Work at moderate speed with light pressure , crossing your passes to homogenize the surface condition.
- Refill the brush in small touches to avoid saturation and heating.
- On metal (Cr-Co), increase the speed in stages while monitoring vibrations and temperature.
- Clean the part between steps and blow the brush to remove any residual grit; finish, if necessary, with a polishing paste.
How to avoid overheating and preserve shine?
The key is to combine moderate speed , low pressure and smooth trajectories.
- Don't stay static: move in crisscross passes, reload the paste frequently but in small quantities, and clean the surface between steps.
- If heat appears, interrupt the cycle and allow the room to cool.
- Check the mounting concentricity and balancing, which are frequent sources of vibration and heating.
- Finally, adjust the grain size: sandpaper for roughing, fine paste for smoothing, polishing to fix the shine.
- This progression limits rework and maintains a stable shine.
How to extend the life of the brush?
After each session, blow the brush to remove paste and moisture, allow to air dry and avoid crushing during storage.
- Avoid excessive speed and pressure, which opens the tuft and tires the horse.
- If possible, dedicate one brush to resin and another to metal to limit cross-contamination.
- Inspect concentricity regularly; replace the tool if you observe runout or asymmetric wear.
- These simple practices improve durability and maintain a consistent, repeatable polish over cycles.
