Frequently Asked Questions

  • Q: How do I choose the right arbor adapter?
    A: Measure your blade's bore (center hole diameter) and your saw's arbor shaft diameter. Select an adapter with an inner bore matching the blade and an outer diameter matching the arbor. When in doubt, consult your saw's manual for the rated arbor size.
  • Q: Are arbor adapters safe to use at high RPM?
    A: Yes — provided the adapter is precision-machined and properly seated. Always ensure the adapter is centered and the blade is securely clamped with the correct flanges before operating.
  • Q: Can I use one adapter for multiple blade sizes?
    A: An adapter is specific to a bore-to-arbor size combination. If you run blades with different bore sizes, you will need a separate adapter for each bore size.
