THE X-WEIGHT CLOTH BACKING OF 3M™ CROSS PAD 341D SUPPORTS BOTH GRINDING AND POLISHING APPLICATIONS. IT HAS A CLOSED COAT OF ALUMINUM OXIDE ABRASIVE SECURED WITH A HEAT-RESISTANT RESIN BOND. THIS CROSS PAD WORKS WELL WHERE CLOSE-TOLERANCE POLISHING OR DEBURRING IS NEEDED. A CROSS PAD ATTACHES TO A THREADED MANDREL (SOLD SEPARATELY) THAT ATTACHES TO A ROTARY TOOL SUCH AS A DIE GRINDER OR DRILL. TOGETHER THE MANDREL AND CROSS PAD ENABLE THE USER TO GRIND OR FINISH THE INNER CONTOURS OF VARIOUS-SIZED CHANNELS. MAX RPM DEPENDS ON THE SIZE OF THE PAD. ALUMINUM OXIDE IS A POPULAR CHOICE AMONG INDUSTRIAL PROFESSIONALS BECAUSE OF ITS FAST CUT-RATE AND LONG LIFE. THIS MINERAL MAKES A TOUGH DURABLE ABRASIVE THAT SELF-FRACTURES TO EXPOSE FRESH CUTTING EDGES WHEREAS TRADITIONAL NATURAL ABRASIVES DULL MORE QUICKLY. DUE TO ITS FAST CUT-RATE HARDNESS AND STRENGTH IT IS WIDELY USED IN GRINDING APPLICATIONS IN ADDITION TO SANDING AND FINISHING APPLICATIONS. ALUMINUM OXIDE IS SUITABLE FOR A WIDE VARIETY OF MATERIALS IN BOTH WOODWORKING AND METALWORKING INCLUDING FERROUS ALLOYS. RESIN ADHERES THE ABRASIVE PARTICLES TO THE CLOTH BACKING CREATING A STRONG STIFF BOND THAT WITHSTANDS THE HIGH HEAT AND PRESSURE OF HEAVY SANDING. APPLICATIONS INCLUDE BLENDING CLEANING INTERNAL DIAMETERS DEBURRING DEBURRING INTERNAL DIAMETERS GRINDING POLISHING POLISHING INTERNAL DIAMETERS STRAIGHT SHAFT GRINDING
