Product Information
Full details
The Sealey FD11540 Zirconium Flap Disc is an essential abrasive tool for metalworkers, fabricators, and DIY enthusiasts who require efficient surface preparation and material removal. Offering superior durability compared to standard sanding discs, this 40-grit flap disc excels at heavy-duty tasks like descaling, derusting, and weld preparation. While its coarse 40-grit rating is perfect for rapid stock removal, users should note that it is not designed for fine finishing or polishing applications.

FAQs
Can I use this disc on wood?
This disc is designed primarily for metalworking, specifically derusting and weld prep; it is not recommended for wood.
Does this disc require a backing pad?
No, the Sealey FD11540 has a rigid integrated backing, so it attaches directly to your angle grinder.
What is the maximum RPM for this disc?
Always check the rating stamped on the disc and ensure your grinder does not exceed that limit.
Is 40 grit too coarse for my project?
40 grit is an aggressive coarse grit; if you need a smoother surface finish, you would need to follow up with a finer grit flap disc.
Will this fit a 125mm grinder?
Yes, it will physically fit the spindle, but it will be slightly smaller than the standard 125mm disc size, providing less surface contact.
Troubleshooting
Disc is vibrating heavily during operation
Ensure the disc is properly centered on the spindle and the locking nut is tightened securely.
Disc stops cutting effectively
The disc may be 'glazed' from too much pressure; try cleaning the surface or checking if the abrasive material has reached the end of its lifespan.
Flaps are tearing prematurely
Avoid catching the disc on sharp corners or applying excessive side-loading pressure.

Setup, Compatibility & Care
