Exceptionally well-suited to surface and edge grinding. The fibre backing strengthens the abrasive disc and improves stock removal.

The VICTOGRAIN abrasive triangles are fixed to the substrate on one of their sides. This means they are securely fixed in place and, together with their slim design, offer an extremely large chip space in order to further improve machining efficiency. The structure of the triangular VICTOGRAIN has also been specially adapted to maximize results. The very small crystals inside the triangles ensure optimal wear characteristics as sharp cutting edges are always exposed, but only the minimum amount of abrasive grain/the triangle breaks off. By combining all these properties together, users benefit from the ultimate, constant performance during cool grinding and an extremely long tool life together with consistent workpiece surface roughness.

The CD clamping system has a threaded connection with female thread (metal/plastic) on the tool side. Also suitable for the following commonly used systems: PSG, Power Lock Type II "turn on", SocAtt, Turn-On.

  • High economic efficiency as tool can be changed quickly.
  • Very comfortable due to ease of use and low-vibration working.
  • No disruptions in use due to adhesion, slipping or coming loose.
  • Efficient machining process with fast work progress, long tool life, less heat build-up in the workpiece, and a lower power output required for the tool drive thanks to VICTOGRAIN abrasive grain.
Recommendations for use
  • Use COMBIDISC midget fibre discs with an abrasive disc holder on flexible shaft drives with an angle handpiece, or small compressed-air or electric angle grinders.
  • Use grinding oil that is suitable for the material in order to significantly increase the tool life and the abrasive performance of the tools.
Ordering notes
  • Please order abrasive disc holder separately.
Safety notes
