Description
4" X 1" X 5/8" un-mounted flap wheel 60 grit with aluminum oxide coated cloth flaps that gently remove material from flat or contoured metal, wood, rubber, fiberglass, or plastic.
Designed for use on stationary machinery like bench grinders, pedestal grinders, or straight finishing tools with a 5/8 inch arbor.
Perfect For
-
Contour Sanding: Because the cloth flaps are flexible, they "conform" to the shape of the workpiece. This makes them the gold standard for sanding curved furniture legs, bowls, or molded metal parts.
-
Medium Surface Cleaning: The 4-inch diameter provides a smaller overall size for getting into cramped spaces.
Avoid For
-
Heavy Stock Removal: If you need to grind down a thick weld bead or reshape a heavy piece of steel, a solid grinding wheel or a flap disc is much more efficient.
-
Precision Edging: Because the flaps are flexible, they will "round over" sharp corners. If you need to maintain a crisp, 90-degree edge, a flap wheel is the wrong choice.
-
High-Pressure Applications: Pushing too hard against a flap wheel doesn't make it cut faster; it just generates heat and destroys the cloth flaps. These tools work best with light to medium pressure.
FAQ
What is the difference between a "mounted" and "un-mounted" flap wheel, and when should I choose the un-mounted version?
A mounted wheel has a built-in 1/4" shank meant for portable drills or die grinders. An un-mounted wheel, like this 4" model, has a 5/8" center arbor hole. You choose the un-mounted version when you are working with a stationary bench motor, pedestal grinder, or lathe. Because the tool is stationary, you can use both hands to manipulate the workpiece, giving you far superior control and allowing you to work on much larger projects than a handheld tool could handle.
How do I know which grit to choose for my project?
If you are dealing with heavy rust or deep scratches in wood, start with a 60 grit. This will move material quickly but leave a visible scratch pattern.
