Super Tack 15 Hole Backing Plate

6-Inch 15-Hole Backing Plate for Super Tack Discs

The Eagle Abrasives Super Tack 15-hole backing plate (part 01456) is the 6-inch hook-face pad that Super Tack velour-backed sanding discs grab onto. Eagle Abrasives distributes Kovax abrasives in the US, and Super Tack is the Kovax hook-and-loop attachment used across their 6-inch disc line. The pad measures 148 mm, threads onto the sander with a male 5/16"-24 stud, and is rated to 12,000 RPM. Its 15-hole vacuum assist pattern runs through the yellow foam body, so on a sander hooked to dust extraction, a matching 15-hole disc pulls sanding dust through the pad instead of smearing it across the panel. A plate whose hook face has worn smooth lets discs creep and fly off mid-pass, and that's the usual reason to replace it.

Load it with Super Assilex 6" 15-hole discs, K-600 through K-1500, for blending clear coat and taking out shallow defects before polishing, or the diamond-grain Magic Sanding Disc for scuffing OEM e-coat. Press each disc on with its holes lined up over the pad's, since a disc set a few degrees off blocks extraction and loads up faster. The rest of the Eagle Abrasives lineup covers sheets, blocks, and 3-inch discs for hand and spot work.

What Makes it Great:

🔩 5/16"-24 Threaded Stud: The male stud threads into any orbital sander with a 5/16"-24 female spindle, a common pad thread on US air sanders.

🌀 15-Hole Vacuum Assist: The holes carry dust from under the disc into the sander's extraction, which keeps the abrasive cutting and the panel visible while you work.

🧲 Super Tack Hook Face: Velour-backed discs go on with a firm press and come away with a pull, so a grit change from K-800 to K-1500 takes seconds and a partly used disc can go back on later.

⚙️ Rated to 12,000 RPM: The maximum speed is printed on the back of the pad. Check your sander's free speed against it before the first run.

Frequently Asked Questions

What thread is the Super Tack backing plate?

A male 5/16"-24 stud. It is not M8: 5/16"-24 has a pitch of about 1.06 mm and M8 is 1.25 mm, so the two look close but will cross-thread. Confirm your sander's spindle before ordering.

Will it fit a RUPES Skorpio III sander?

No. The Skorpio III holds its plate with a RUPES socket cap screw (9.715) rather than a threaded stud. It needs the RUPES Skorpio III 6" Backing Plate, part 981.500.

Do I have to use 15-hole discs?

Any 6-inch Super Tack disc will stick, but a disc without holes, or a no-hole interface pad, covers the pad's holes and shuts off extraction. Use a 15-hole disc to keep the vacuum assist working.

Why does the edge of my backing plate tear?

Running the pad edge into a sharp body line, door edge, or trim piece tears the foam, and Eagle's label says not to use a pad once it's torn. Keep the edge off sharp corners and finish those areas by hand.
