5-inch SC-DH Surface Conditioning Disc
The 3M 04303 SC-DH hook-and-loop disc is a non-woven abrasive designed for surface conditioning on power sanders. Its aluminum oxide construction delivers consistent finishing action on metal, wood, or composite surfaces. The five-inch diameter fits standard random orbital sanders equipped with hook-and-loop backing pads.
Best for light finishing and prep work
This very fine grade disc suits technicians blending scratch patterns, removing light oxidation, or preparing surfaces for coating without aggressive stock removal. The teal color identifies the very fine grade within the Scotch-Brite system. Users needing heavy material removal, coarse grinding, or vacuum-assisted dust extraction should select a different abrasive type.
Very Fine grade aluminum oxide non-woven
The single specification that determines fit is the Very Fine grade aluminum oxide non-woven construction, which sets the cutting aggressiveness and surface finish profile. This grade targets final finishing steps rather than dimensioning or heavy defect removal. Verify that your sander accepts five-inch hook-and-loop discs before purchasing.

Questions about this item
How often will the 5-inch Very Fine aluminum-oxide disc need replacing during daily prep work?
Disc life depends on material hardness and pressure; expect to swap when the teal surface dulls or loading reduces cut rate.
What stops the non-vacuum SC-DH disc from cutting efficiently during a long session?
Heat buildup and resin loading on the non-woven face are the first limits; pause to tap dust clear and let the pad cool.
Does the hook-and-loop backing get hot or noisy when the sander runs all day?
The backing stays cool; only the abrasive face warms, and the disc itself adds no audible noise beyond the tool motor.
