SAITLAM PN with silicon carbide grain is the flap disc for marble, granite and natural stone from SAIT Abrasivi, made in Italy and supplied in Lebanon by Rousse. It comes in 115 mm for angle grinders and 180 mm for larger grinders.
A flap disc carries overlapping abrasive-cloth flaps on a semi-flexible backing, so it grinds and finishes in one step: it removes material like a grinding wheel but leaves a smoother finish, runs cooler and quieter, and keeps cutting as fresh grain is exposed.
Applications
- Shaping, bevelling and rounding marble and granite edges
- Levelling joints and lippage on stone and terrazzo
- Removing marks before polishing
- Working on concrete, tiles and other hard mineral materials
Choosing the grit

FAQ
Flap disc or grinding wheel?
A grinding wheel removes material fast but leaves a rough surface. A flap disc removes material and finishes at the same time, with less heat, vibration and noise, so you often save a finishing step.
Why silicon carbide for stone?
Silicon carbide is a sharp, hard grain that cuts stone and other mineral materials better than aluminium oxide, which is made for steel.
What do people call it in Lebanon?
Usually disc mdala3 or wara2 mdala3 (ديسك مضلع); also flap disc.
