FiboTec multi-hole

Taking inspiration from nature and the Fibonacci Sequence, sia Abrasives has developed a groundbreaking new hole pattern for its abrasives.

The holes in the abrasive disc are arranged on opposing spirals such as those found in a sunflower. In sanding applications this hole pattern provides superior dust extraction, significantly reduced clogging and longer life of abrasive materials.

  • Works up to 50 percent faster due to better dust extraction and less clogging
  • Higher productivity
  • Higher process stability
  • Better occupational health and safety

Sianet from Sia Abrasives

Sia abrasives have extended their product range with the net-backed abrasives 7900 Sianet and 7500 Sianet.

The new abrasive range can be used for coarse and fine grinding of different materials and surfaces thanks to the differing grains and grit used. The open net design provides the ultimate dust extraction and hole compatibility.
