Calcined Aluminum Oxide Flap Discs

Our calcined aluminum oxide flap disc range includes five diameter and center-hole combinations, with grits listed below. For repeat orders or replacement sourcing, please provide the specifications of your current disc so we can review the required configuration.

If you are comparing this range with standard aluminum oxide flap discs, tell us about the workpiece and operation. The abrasive name alone is not enough to confirm a suitable replacement.

Matching Your Current Product

When sourcing a replacement disc, please include:

• The workpiece material and grinding or finishing task.
• The size and grit currently used.
• Your grinder model.
• A photograph of the disc label, front, and backing.
• Any issue you want to address with the replacement.

These details give us a clearer basis for reviewing your requirements than size and grit alone.

Bulk Orders and Packaging

Please list the quantity required for each size and grit. If the order needs your own label or packaging, include the artwork or a reference image with your enquiry.

Minimum order quantities, packaging options, and lead times are confirmed for the requested configuration.
