Quick Summary
The SI FANG 5Pcs 115mm high density curve flap disc set is made for angle grinder sanding and grinding where a shaped disc is more useful than a flat one, especially on fillets, welds and inside corner areas.
Who It Is Best For
This set is best for people who need to work on contour areas, edge work and harder to reach locations. It suits buyers looking to grind, sand or finish weld seams, weld marks, burrs and curved surfaces with a disc shape designed for more precise access.
Why Buyers Choose It
Compared with a traditional T27 or T29 flap disc, the radial rolled curved shape is intended for more detailed work in awkward areas. The product description says the angled flaps provide greater surface contact, while the zirconia abrasive is described as giving a sharp cutting edge.
- Curved shape for fillets and inside corners
- Suitable for flat and curved surfaces
- Designed for contour work and repair applications
- Fibreglass backing plate for a lightweight feel
- Built for efficient use and long service life
What To Know Before You Buy

- Pros: Better access in difficult areas, suitable for flat and curved surfaces, made for weld and edge work
- Cons: 60 grit may be too coarse for very fine finishing tasks
Real World Use
