3M 07451 Hook-and-Loop Surface Conditioning Disc 4 in Medium

SKU CH-HKNX-Q56RX MPN 07451

A 4-inch medium-grade surface-conditioning disc with hook-and-loop fastening for sanders

  • TypeSanders
  • Hook-and-loop backing enables quick disc changes
  • Medium-grade aluminum oxide suits general surface preparation
  • Four-inch diameter fits standard orbital sanders
  • Non-vacuum design simplifies use on portable tools
  • Load-resistant coating reduces clogging during extended sanding

Surface conditioning disc, hook-and-loop, 4 in

This 3M hook-and-loop surface conditioning disc measures four inches in diameter and uses an aluminium-oxide non-woven abrasive in a medium grade. The no-hole, maroon disc attaches directly to a compatible backing pad for finishing, blending or light deburring work on metal, composite or painted surfaces.

For finishing and prep tasks.

The medium-grade abrasive suits operators who need consistent surface preparation, blending of tool marks or light rust and paint removal without gouging the workpiece. It will not satisfy users who require aggressive stock removal, very fine polishing grits or a vacuum-hole pattern for dust extraction.

4 in no-hole hook-and-loop mounting

The disc relies on a four-inch hook-and-loop face with zero vacuum holes, so it fits only backing pads of the same diameter and attachment style. Buyers whose sanders use a different diameter, a bolt-on or adhesive mount, or a multi-hole dust-collection pattern cannot use this disc.

Questions about this item

What does the Medium grade mean when the disc is spinning on a sander?

The Medium grade uses aluminum oxide abrasive on a non-woven web to blend, deburr and finish surfaces without removing heavy stock.

How does the hook-and-loop backing work with a standard 4 in backing pad?

The disc presses onto any 4 in hook-and-loop pad; the loop face grips the pad hooks so the disc stays centred during use.

What clearance does the 4 in diameter need on the tool and workpiece?

The disc measures 4 in across, so the sander must accept a 4 in pad and the work area must allow that full diameter to rotate freely.
