What abrasive composition does it use?

It combines aluminium oxide with a proprietary precision-shaped ceramic grain to deliver controlled cut rates and wear performance.

How should the product be stored to preserve performance?

Keep in original packaging at 16°C to 26°C and 35 to 50% relative humidity on a first-in, first-out basis to avoid premature degradation.

Which operating speeds are supported for larger disc sizes?

Maximum orbits per minute vary by disc diameter with higher allowable OPM for medium sizes and lower for the largest sizes to match tool specifications.

How does the attachment system affect alignment during use?

Loops are incorporated into the net backing so holes need not be aligned with the backing pad, simplifying fitment and repeatability.
