Abrasive Fibre Discs
Abrasive Fibre Discs or Fibre sanding discs are the most common sanding disc for grinding a variety of woods and metals.
Below we have highlighted some basic recommendations to give you a head start:
Ceramic (FX) Abrasive Fibre Discs: High performance grinding on stainless steel, scale removal on mild steel and also coarse grinding on aluminium
Zirconia (K3K) Abrasive Fibre Discs: Normally recommended for medium aggression and general purpose grinding on stainless steel
Aluminium Oxide (KFK) Abrasive Fibre Discs: All grinding on non-ferrous metals and for finish sanding on mild steels
Surface Conditioning (VTFA) Abrasive Fibre Discs: Designed to refine, blend and remove scratches and damage from a surface
Abrasive Fibre Discs FAQs
What difference does the back up pad make for sanding discs?
Sanding / fibre discs are bonded to a thin layer of vulcanised fibre which makes them quite flexible in use. To reduce that flexiblity then selcting the correct back up pad will make all the difference.
FIZ pads: The 'Z' stands for soft. These are most commonly used with the surface conditioning discs for final finishing
FIW pads: This is our intermediate back up pad. use for general purpose and low aggression sanding.
FIH pads: The 'H' stands for hard, but don't let that put you off. They give lots of control and increase the speed of cut you will get from your sanding disc. We particularly recommed these for use on coarser grit ceramic and zirconia sanding discs
Which sanding disc should I use for sanding stainless steel sheet metal tig welds?
If you care about life and good control of your process then we would recommend our FX P80 or even P120 grit Cibo Ceramic discs, particularly if you need to finish the stainless steel afterwards.
If the finish is less important then the FX 60 grit Cibo Cermic discs will obviously give a much faster cut rate and a longer disc life.
With both processes we would recommend the FIH back up pads to ensure longer life and great control.
Which sanding disc works best on galvanized metal?
When sanding galvanized metal the most common application is for the removal of excess metal on the surface in preparation for painting. Too high aggression could easily result in grinding through the galvanized surface so we would recommend our KFK aluminium oxide sanding discs in P80 or P120 grit on the FIW or FIZ back up pads.
