  • Product typeSanders
  • Very fine grade prepares surfaces for finishing without deep scratches
  • Aluminium oxide abrasive resists loading to maintain consistent cut

  • Non-woven construction conforms to contours for uniform surface conditioning
  • 7 inch diameter fits standard 7 inch hook-and-loop sanding pads

7 in Very Fine Surface Conditioning Disc

This 3M SC-DH disc uses a hook-and-loop backing for quick changes on compatible sanders. The very fine grade aluminum oxide abrasive suits light finishing, blending and surface preparation tasks. It is built for professionals and DIY users who need consistent results on metal, wood or composite surfaces.

Non-Vacuum Design With Load Resistance

The disc has no vacuum holes so dust extraction relies on the tool or ambient airflow. Load-resistant properties help reduce clogging during extended use, keeping the cutting action steady. Heat and noise levels follow the sander itself rather than the disc.

Hook-and-Loop Mounting For Fast Swaps

The hook-and-loop face locks onto standard backup pads without tools, letting operators change grits or discs in seconds. Blue colour coding identifies the very fine grade at a glance. No hole pattern means full surface contact on flat or contoured workpieces.

Questions about this item

How do I attach the 7 in hook-and-loop disc to my sander and what step do people often miss?

Press the disc firmly onto the hook-and-loop pad so the entire 7 in surface engages; the step people miss is cleaning the pad first so dust does not prevent a full bond.

When will this Very Fine aluminum-oxide disc need replacing?

Replace the disc when the blue non-woven surface becomes glazed or the cut rate drops noticeably; there is no fixed hour count because load resistance varies by workpiece.

What limits continuous use on a 7 in sander?

Heat buildup in the non-woven web is the first limit; extended runs can soften the resin bond and reduce the Very Fine finish quality.
