Frequently Asked Questions

  • Q: What backer pad do I need for flexible sanding discs?
    A: Match the backer pad diameter to your sanding disc size (4", 5", or 7"). Use a hook-and-loop backer pad for quick disc changes. For wet use, ensure the backer pad is rated for wet applications.
  • Q: What size expanding drum do I need for my cab machine?
    A: Most 6" cab machines use a 6" x 2.5" expanding drum. Verify your machine arbor diameter (typically 1") and drum bore size before ordering.
  • Q: Can I repair a torn sanding belt with splicing tape?
    A: Yes — belt splicing tape can repair minor tears and re-join belt ends. For heavily worn or damaged belts, replacement is more cost-effective than repair.
