5" Purple Ceramic Flap Discs — Type 29 Angle Grinder Discs

Reviews

1. E Emmanuel Solano 5/5

   Gets mower blades razor sharp

   Good pack of discs — I sharpened my lawn mower blade to a clean, precise edge and it now cuts turf much better. Exactly what I needed.

2. T Thomas P. 5/5

   Very good — fits multiple grinders

   The 20-pack and selected grits suit many jobs. They mounted easily on my Makita and another cordless grinder, and performance was satisfying for workshop tasks. They show normal wear but seem to last a bit longer than some alternatives. Price felt fair for the results.

3. T Topscore1632 5/5

   Complete kit for most grinding jobs

   This pack covers many tasks — rust, paint and grime removal — and lets you move through grit levels as needed. I stripped a mower deck before welding and the discs resisted clogging, so each one lasted well. Good all-around supply.

4. D D Carpenter 5/5

   Reliable for frequent use

   I use these up quickly, so I keep reordering the mixed pack. They fit my grinder and removed paint and rust while cleaning up welds. Each disc lasted a good while before replacement.

5. T Terry G. 5/5

   Dependable for medium to heavy rust

   These flapper discs remove medium to heavy rust on flat metal surfaces effectively — a step up when a wire brush won't suffice. They are consumables, but with proper technique last similarly to other brands. The mixed grits are convenient, and the discs can be used on non-metal materials if you avoid clogging the abrasive; an air nozzle helps keep them clean.

6. D Donna-marie Rawle 5/5

   Great for vehicle body and rust prep

   Used this 20-piece set to strip paint from van panels before welding. They cut through paint and rust cleanly and run cooler, so I wasn't worried about warping panels. They also outperformed a wire brush at removing surface rust and saved time.

7. C Customer Review 4/5

   Sharp, varied grits for prep and finish

   Ordered the 115mm mixed-grit pack and they fit my grinder well. Started with 40 grit to clear rust from angle iron for welding, then used 120 to clean brackets before painting. They worked quickly and made welding prep straightforward.

8. R RFH 5/5

   Solid assortment, measured performance

   This mixed-grit pack delivers on dimensions and fits my grinders without issue. Low sparking, low vibration and quick cutting are noticeable. Ceramic lasts longer than aluminum oxide for heavy removal, though these discs are slightly thinner than premium options, which affects perceived durability.

9. C Cyberchaz 5/5

   Good quality and versatile use

   Quality matches what you'd expect from store-bought ceramic flap discs. I use them for smoothing metal and sharpening mower blades; they fit my battery grinder perfectly. Longevity depends on material and pressure, but these have held up through multiple jobs. Confirm the size for your grinder before ordering.

10. C CA Contractor 5/5

    Handy for coastal restoration and heavy rust

    As a contractor doing exterior hardscape near the coast, these mixed ceramic discs handled corroded metal and old paint very well. They mount flush to standard arbors and cut through layered buildup while staying cooler than conventional discs. They also seem to tolerate damp conditions better than older abrasive types.

11. G Ground Loop Garage 5/5

    Comfortable angle and solid build

    These flap discs are decent; the slight bevel works well since grinders are often held at an angle. Check clearance between the guard and disc before fitting. Wear rate is comparable to other flap discs — pushing hard speeds wear and heat. The base looks like reinforced fiber and the flaps are firmly attached, not floppy.

12. N NicBLAM 4/5

    120-grit cuts and tears through rust

    Picked up the 4½" 120-grit discs and they feel well made — flaps are securely bonded and the center hub is solid. The 120 grit spins fast and removes rust and scale efficiently. Great value for bulk buying; my grinder chewed through the work and the discs kept up.
