What the product is and who it is for
The Arc Abrasives 30474 is a pressure-sensitive adhesive sanding disc coated with aluminum oxide on a heavy cloth backing. It is built for aggressive stock removal on metal, wood or composite surfaces where an extra-coarse grit is required.
What the bundled accessories
The disc uses a PSA attachment so it bonds directly to a compatible backing pad without extra adhesives or mechanical clamps. The closed-coat aluminum oxide layer resists loading while the X-weight cloth backing withstands high pressure and heat during extended sanding sessions.
What to check on your existing setup before ordering
Verify that your sander accepts eight-inch diameter discs and that the backing pad is rated for PSA mounting. Ensure the tool speed and torque match the demands of 36-grit material removal to avoid premature wear or surface damage.

Questions about this item
When will the 36 grit aluminum oxide cloth disc need replacing?
Replace the disc once the aluminum oxide grains dull or the cloth backing tears, which occurs after the abrasive surface no longer cuts efficiently.
What stops the 8-inch non-vacuum disc from cutting during extended sanding?
Heat buildup and loading of the closed-coat surface limit sustained cutting before the disc must be swapped.
How much heat does the X-weight cloth backing generate in all-day use?
The X-weight cloth backing resists heat buildup better than paper, but the closed-coat aluminum oxide still warms the workpiece during continuous sanding.
