    There are a whole world of flap discs but which flap discs are best for wood? The primary reason for using flap discs on wood is for high aggression shaping or for removing band saw marks. Of course it depends on whether you are sanding hardwoods or softwoods. Softwoods will wear down easily but can cause a disc to clog up. Hardwoods with a high silicate content can be more difficult to sand than steel.

    When sanding hardwoods you can use our zirconia flap discs but if you are looking for fast stock removal then see our report below on the Cibo Ceramic flap discs.

    The biggest issue with using a flap disc on pine and other softwoods is the risk of the disc clogging up. If too much heat is generated then resinous woods can cause the surface of the flap disc to load. To prevent clogging use is a premium abrasive grain combined with a cotton backed material such as the Cibo FSC. The zirconia grain will sand quickly. The open cotton backing allows the cloth to breakdown consistently allowing you to use the full disc life. For aggressive shaping the best disc will be the FSC 40 grit.

    Sanding hardwoods can sometimes be more difficult than sanding metal. We therefore recommend a good quality abrasive grain with a stronger backing polyester backing. For occasional flap disc sanding of hardwoods we recommend our FNC zirconia flap discs. The FNC discs have the premium grit and heavy duty backing you will need. If you need to use flap discs regularly on hardwoods. For example, for removing band saw marks then the best flap disc for wood is the FTC Cibo ceramic flap discs. Please read on to see why we recommend the ceramic flap discs for grinding hardwoods. The most aggressive 115mm ceramic flap disc is the Cibo FTC 40 grit.

    Premium Ceramic Flap Discs for Hardwood Sanding

    Did you know that ceramic flap discs are excellent on woods? If you are a regular flap disc user you will know that the Cibo Ceramic Flap Discs are fantastic when grinding stainless steel, steel and other hard metals but they are also excellent on a variety of woods.

    When working on wood, ceramic flap discs provide faster, cooler cutting and increased life span (minimum of 3x life) when compared to premium zirconia flap discs. Take a look at what happened when our neighbours from Wilkinson’s Joinery wanted a solution for removing their band saw marks.

    When removing band saw marks from wood, more specifically in this case on green oak for doorway lintels, it is important that the marks are removed without damaging the surface below. Therefore we were convinced that our ceramic flap discs would do the trick.

    Time Saving Sanding Products

    Using the flat Cibo Ceramic flap discs allows the operator to work at a very shallow angle. A shallow angle reduces the risk of digging in to the oak.  And with the grinding aids there was no reason to be worried about the disc clogging up. It would take a lot more than green oak to make the ceramic flap disc ineffective!

    Another important factor when supplying the correct product for Mark and his team was the speed of cut.  No one wants to be stood grinding for hours on end. You can see below how easy it was for Wilkinson’s to remove the band saw marks from the lintels.

    Another choice you have when working with ceramic flap discs is whether you need a flat or conical shaped disc.

    Conclusion

    As I’m sure you’ll agree, the flat ceramic flap discs (FTF’s in this case) did a really nice job of removing the band saw marks and leaving a neat, consistent finish. The discs did not grind into the wood and cause damage, it simply did what was expected.

    In the past, stripping discs or even grinding discs may have been used to do similar jobs but the results would be incomparable.

    Switch over to ceramic flap discs to improve the quality of your job. Reduce noise and vibration.
