Mopillos 113Pcs Angle Grinder Sanding Kit
The Mopillos kit provides 110 sanding discs across 40, 60, 80, 120, 180, 240, 320, 400, 600, 800, and 1000 grits.

The kit converts a grinder into a versatile sander, enabling easy installation and removal of discs. The backing plate threads directly onto the angle grinder spindle, compatible with 5/8-11 threaded tools. The discs are made with aluminum oxide for efficient grinding, paired with strong base paper and adhesive to resist tearing and manage heat dissipation. Up to 12,200 RPM is supported, and shank adapters allow use with drills for added flexibility.

The flexible polyurethane backing enhances balance and edge polishing on uneven surfaces, while providing durability for aggressive sanding. These discs outperform many random orbit sanders for heavy material removal and provide broad compatibility across wood, metal, and other materials.
Pukamam 24 Pack Flap Discs for Angle Grinder
The Pukamam set includes 24 flap discs, 4 1/2″ in diameter with grits 40/60/80/120 (six discs of each grit). The discs use zirconia abrasives for durability and strength, suitable for metal and wood. The standard 7/8″ arbor size fits most angle grinders up to 13,300 RPM, making these discs a solid option for heavy stock removal and consistent blending across multiple tasks.
Buying Guide
Key purchase considerations help you select the right sanding solution for your grinder and project:
- Grit range and variety: For initial material removal, coarser grits (40–80) work best; for finishing, finer grits (180–1000) produce smoother surfaces. Sets offering a wide range reduce the need to buy multiple packs.
- Backing type: Hook-and-loop (Velcro) backs are common and allow quick disc changes. Foam-backed or sponge cushions dampen vibration and help with edge polishing on uneven surfaces.
- Disc format: Flap discs excel at metal finishing and aggressive stock removal, while standard sanding discs with backing pads are versatile for wood and plastics.
- Arbor compatibility: Ensure 5/8-11 threading (or the specific size of your grinder) to avoid adapters. Some kits also include adapters for drill use or other tool types.
- Durability and heat resistance: Zirconia-based discs offer high heat tolerance and longer life for demanding jobs, especially on metal. Aluminum oxide discs are common and affordable for light work.
- Speed rating: Confirm your grinder’s RPM matches or stays below the disc’s maximum RPM to prevent disc failure or unsafe operation.
- Application mix: Wood, metal, and plastics react differently to sanding; choose discs designed for multi-surface use or separate packs for specialized tasks.
When evaluating sets, consider your typical projects, the tools you own, and the feasibility of using a single backing pad across multiple disc types. Higher-quality zirconia flap discs tend to last longer under heavier workloads, while hook-and-loop sanding discs offer easier changes for projects requiring frequent grit changes. For beginners, a large, mixed-grit kit with a foam-backed pad can provide a straightforward, all-in-one solution.
