Flap discs are abrasive tools for metal fabrication that provide grinding, blending and finishing at low cost with just one tool attachment. They have been the fastest-growing category in the abrasives industry for the past decade. They are excellent for reducing gouging and burning during cutting because they cut cooler, making them a preferred choice for metal fabricators. Not only are flap discs lighter and easier to control, but they also require less downtime for product changes, which can reduce vibration, noise, and even fatigue.
Flap discs type
Flap discs are mostly used on right-angle grinders, so a hub is specially designed to do metal processing on the surface. The flaps can be used both inclined and flat. Choosing the correct shape for your Flap discs is critical to your finished product. Each flap disc shape has different performance characteristics, so choosing the right flap discs for your metalworking project is very important Type 29 tapered flap discs are recommended for removing heavy layers of paper, as they have angled flaps that are useful for edge and contour work. The angled flaps allow greater surface area contact, making them perfect for cutting on flat surfaces. When you need speed and cuts look no further than the type 29 flap discs. Type 27 flat flap discs are fine for finishing metal on flat surfaces, although they can be used for simple edge work. If you just want to mix, smooth and polish metal, the Type 27 Flat flap disc is the best choice for you.
Abrasives for Metalworking
With flap discs, you need the right abrasive. For metalworking, three types of abrasives are recommended: alumina, ceramic alumina, and zirconia alumina, which are designed to shape and smooth metal. Generally, you can use alumina grit for small projects, ceramic alumina for stainless steel or high alloy materials, and zirconia alumina for carbon and mild steel applications.
