Q: What are the advantages of a flap wheel?

Advantages. The advantages of a flapwheel over a traditional disk are twofold: The separate flaps each attack the workpiece surface at a slightly different angle, and this varies slightly with tool angle. This avoids the common problem with flat sheets, where they produce repeated identical scratches.

Q: What is the difference between flap wheel and grinding wheel?

Flap discs are ideal for grinding, blending, finishing, and polishing surfaces, as well as removing rust, paint, and weld seams. Grinding discs are typically used for heavy-duty material removal, such as removing large welds, and shaping and smoothing metal edges.

Q: What is the best flap disc for grinding welds?

Flap discs are good for removing heavy weld seams and excess material while providing a long service life: For general use, the recommendation is a 60-grit ceramic flap disc. For greater speed and stock removal, a Type 29 conical is the best choice.

Q: What is a flap disc grinding wheel used for?

A flap disc is an abrasive product used to contour and shape metal. It consists of overlapping abrasive flaps glued to a backing plate and is regularly used for welding, machining, heavy-duty equipment work, and industrial maintenance. Common applications include: Cleaning flash from molds and castings.

Q: What is the best grit for flap discs?

Deburring and deflashing: 60 grit abrasive grain is ideal for deburring and deflashing work. Rust removal and blending: Abrasive grit in the more expansive range from 60 to 80 is optimal for finer work like rust removal and blending.

Q: Which grit flap disc would leave the smoothest finish on metal?

For finishing and sanding metal, a 120-grit flap disc could be your best option. Flat head flap discs best suit the purpose of finishing metal.

Q: What is the best flap wheel for stainless steel?

Designed for both mild and stainless steel, flap wheels made from zirconia (or zirconium) abrasive ribbon (blue / green in colour) are ideal for use on most metals including stainless steel. Other flap discs on the market made from using aluminium oxide abrasive ribbon are not suitable for use on stainless steel.

Q: Can you put a flap disc on a bench grinder?

Unmounted large flap wheels can conform to most shapes and are especially effective on pipes, tubes and other cylindrical items and are designed to be used on a bench grinder, pedestal grinder, or straight finishing tool with a 1 inch arbor.
