What’s a flap wheel used for?
A flap wheel is a versatile abrasive tool. Flap wheels are made of coated abrasive flaps arranged radially around a hub. They are flexible and allow adaption to the shape of the workpiece. Flap wheels are suitable for applications such as deburring, finishing, polishing and cleaning.
What is the finest flap disc?
Type 27 Flat flap discs are the best choice for finishing. Flat flap discs are used primarily on flat surfaces. They are the best choice for blending and smooth finishing. Standard Density flaps are excellent for heavy-duty applications and rapid stock removal.
How long should a flap disc last?

How do I choose a flap disc?
Generally, standard-density flap discs are excellent choices for aggressive stock removal and demanding industrial applications. High-density flap discs, on the other hand, are best suited for curved or uneven surfaces, or for blending and finishing rather than heavy stock removal.
What is the difference between Type 27 and Type 29 flap disc?
Type 27 is used for grinding the plane and outside corners. The grinding surface of the curved flap disc, Type 29, has an upward curvature, allowing it to grind at a steeper angle. It is mainly used for grinding of corners and edges. When speed and cutting ability have higher requirements always recommend the Type 29.
What is the difference between T27 and T29 flap disc?
Flat (T27) has smooth grinding surface and is mainly used to grind the plane and the outside corners. The grinding surface of the curved flap disc (T29) has an upward curvature, which gives the T29 flap disc a better cutting ability in the plane.
Can I use a flap disc on wood?

Can you use a flap disc on aluminum?
Yes. Because ordinary flap discs such as the cheaper flap discs with Aluminum Oxide surfaces are not designed for use on Aluminum. When you use those flap discs they will run hot on the metal’s surface, melting the Aluminum.
What is a Dremel Flap wheel?
The Dremel 3/8 in. Grit Flap Wheel continuously exposes new abrasives to prevent clogging and to provide a uniform finish. Ideal for grinding and polishing flat and contoured surfaces.
