Choosing the Right Small Radial Disc

Small Disc Formats

We offer small radial discs in unique formats allowing users to increase performance and achieve extra precision:

  • Standard discs are excellent for general-purpose finishing.
  • Knife-edge profiles improve precision & access into grooves and fine features.
  • Multi-layer configurations, such as dual discs & 4-ply systems, increase durability and provide a more consistent working face over extended use.
  • Snap-on discs allow quick and easy transition between grades to reduce down-time.

Why Stacking Matters

For best performance, radial discs should be used in layers:

  • 3 - 6 discs (small sizes)
  • Creates a wider, flexible abrasive face
  • Improves surface consistency
  • Prevents gouging or uneven wear

Typical Applications

Small radial bristle discs are used across a wide range of industries requiring precision and attention to detail:

  • Jewellery polishing (rings, settings, filigree)
  • Dental lab finishing
  • Watchmaking and horology
  • Precision engineering
  • Restoration work
