3M Stikit low profile abrasive disc backup pad provides secure attachment for a 3M Stikit disc (sold separately) on a random orbital sander or other rotary tool. This lightweight, shock resistant backup pad is constructed of firm density foam for sanding flat surfaces and has a tapered edge for applications where some flexibility is needed. Our 3M Stikit low profile abrasive disc backup pad was designed for use with 3M Stikit abrasive discs. The 3M Stikit system was designed for convenient changes between abrasive grades or applications. Stikit abrasive discs come ready-to-use with a pressure sensitive adhesive coating on the backside so that attaching them to the hand block is as simple as pressing on a sticker. Yet they remove cleanly without adhesive residue left on the block. The taper on 3M Stikit low profile abrasive disc backup pad, either 10 or 15 deg, helps it conform to small contours and get inside tight corners. Some Stikit backup pads feature holes for enhanced dust extraction while others like 3M Stikit low profile abrasive disc backup pad. Operators may opt for a backup pad without holes when working on substrates where loading or debris are not as much of a concern. The 6 in Dia disc has a 3/8 in THK, which qualifies it as low profile. Low profile, hard density backup pads are good for flattening and leveling surfaces, because they tackle imperfections without yielding or deflecting. When you anticipate bumps in the road - this backup pad is good to have on hand.
