Frequently Asked Questions
What mandrel size is required to mount this cap?
This cap has a 1/2-inch inside diameter and 3/4-inch length, engineered to slide over a standard 1/2-inch by 3/4-inch expanding rubber drum mandrel. As the mandrel arbor screw tightens, the rubber core expands to grip the interior cloth backing securely.
Is a mounting mandrel included?
Not included.
How does a flat-top abrasive cap differ from a round-nose cap?
A flat-top cylindrical cap provides a square 90-degree corner and a flat end face, allowing work along square internal shoulders and flat bottom recesses where round-nose caps cannot reach. The price per piece steps down with quantity, and the price-break table on this page shows each step.
A coarse 60-grit cap does not ask for patience when cleaning up rough castings or tight channels. Slide it onto your mandrel, spin it up, and let the grit do the heavy cutting.
