LAMA – Saitlam Flap Discs For Metal
ديسكات مضلع للحديد

SAITLAM PN is the general-purpose aluminium oxide flap disc from SAIT Abrasivi, made in Italy and supplied in Lebanon by Rousse. It fits 115 mm (4½”) angle grinders with a 22 mm bore.

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

• Grinding and blending welds on mild and carbon steel
• Removing rust, paint and scale
• Deburring and chamfering edges
• Surface preparation before painting
• Shaping and sanding wood

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.

Can I use it on stainless steel?
It will work, but for stainless steel choose the zirconia SAITLAM Z, WIND or PLANET ONE discs, which run cooler and last longer on hard metals.

What do people call it in Lebanon?
Usually disc mdala3 or wara2 mdala3 (ديسك مضلع); also flap disc.

أسئلة شائعة

ديسك مضلع أو حجر جلخ؟
حجر الجلخ بيشيل بسرعة بس بيترك السطح خشن. الديسك المضلع بيشيل وبينعّم بنفس الوقت، بحرارة وهزّة وصوت أقل، فبتوفّر مرحلة تنعيم.

بينفع عالستانلس؟
بيشتغل، بس للستانلس الأحسن SAITLAM Z أو WIND أو PLANET ONE بالزركونيوم، لأنهم بيشتغلوا أبرد وبيعمّروا أكتر عالمعادن القاسية.
