Flap Wheel 8" x 2" Unmounted Aluminum Oxide, Pack of 5

8-inch unmounted flap wheels: choose the arbor hole and grit

These aluminum oxide flap wheels measure 8 inches in diameter by 2 inches in face width and come in packs of 5. Each wheel has a center arbor hole rather than an attached shank.

Three arbor-hole options

Choose a 5/8-inch, 1-inch or 1-3/4-inch arbor hole. Match the hole to the spindle and approved mounting hardware specified by your machine manufacturer. The hole size alone does not establish compatibility.

Eight available grits

The selector offers 40, 60, 80, 100, 120, 150, 320 and 400 grit. Choose the starting grit for the existing surface and the required finish. These are individual grit options; a pack is not an assortment. Check your selected arbor-hole-and-grit combination before ordering.

Confirm clearance and operating speed

Check that the machine accepts both the 8-inch diameter and 2-inch face width. Verify the required flanges, guarding and operating speed using the machine instructions and the wheel's marked maximum speed. Do not assume that any polishing lathe or bench machine accepts this wheel. Confirm uncertain ratings or mounting requirements before use.

Compare mounted and unmounted wheels

Use the flap-wheel size and mounting guide to compare options. If your tool requires a shank-mounted accessory, review the 3-inch by 1-inch mounted flap wheels and verify their dimensions and attachment against your tool instructions.
