				Type: Sand Paper Flap Disc (Abrasive Flap Disc).
Purpose: Suitable for applications like working on iron metal and wood. Flap discs are versatile, combining the action of a grinding wheel and a sanding disc, often used for weld blending, deburring, rust removal, and surface preparation.
Size: Typically a 4-inch (100mm) diameter with a 16mm bore diameter, which is a standard size for small angle grinders.
Grit Options: Products in this series (or similar ones from the same brand) are usually available in multiple grit sizes, such as:
Coarse: P60
Medium: P80
Fine: P120 (The grit you choose determines the material removal rate and the smoothness of the finish.)
Abrasive Material: Likely made with an Aluminum Oxide abrasive grain, which is common for general-purpose sanding on metal and wood.
Note: While some listings specifically mention a "FUTURE TECH" A033 disc, the name "BADAK TECH FLAP DISC A033" suggests a product line from the brand BADAK Abrasive. The core product type, specifications, and usage remain consistent for this type of general-purpose flap disc.
