Frequently Asked Questions

• Q: What does an arbor reducer flange do?
  A: This flange adapts a 16mm bore wheel to a 30mm spindle, ensuring centered, secure clamping with no wobble or runout.
• Q: Is this flange compatible with my bench grinder or saw?
  A: Designed for machines with a 30mm spindle diameter and 16mm bore wheels or blades. Verify dimensions before ordering.
• Q: What is the difference between 1.5mm and 3.5mm step height?
  A: A 1.5mm step suits setups requiring minimal axial offset. A 3.5mm step provides deeper engagement for additional stability.
• Q: Is this listing for a single flange or a set?
  A: This listing is for a single arbor reducer flange. Order two units if flanges are needed on both sides of the wheel.
