Medium Hook-and-Loop Surface Conditioning Disc

This 3M 14100 disc uses a non-woven aluminum oxide construction on a hook-and-loop backing for surface preparation. The medium grade suits general cleaning, blending and finishing tasks on metal or composite substrates. Its no-hole design fits standard 4-1/2 in backing pads without alignment concerns.

General surface preparation on metal or composite

Suited for operators who need a medium-grade disc for deburring, rust removal or paint preparation without aggressive stock removal. Not suited for heavy grinding, precision polishing or applications that require vacuum extraction through the disc face.

Medium-grade non-woven aluminum oxide abrasive

The medium-grade non-woven aluminum oxide material determines cut rate and finish quality for surface conditioning work. This specification defines whether the disc matches the required surface preparation level.

Questions about this item

How does the Medium grade perform on a real workpiece?

The Medium grade removes surface oxidation and light coatings while leaving a consistent scratch pattern suitable for paint prep or blending.

What does the hook-and-loop interface limit in daily use?

The hook-and-loop face allows quick disc changes but requires a compatible backup pad; it will not adhere to adhesive-only or bolt-on sanders.

What does the 4-1/2 inch diameter need to mount correctly?

The 4-1/2 inch disc fits standard 4-1/2 inch hook-and-loop backup pads used on right-angle grinders or random-orbit sanders with the same bolt pattern.
