DESCRIPTION
Abrasive flap disc are versatile tools for grinding, blending, and finishing surfaces
Abrasive flap disc Shape:
Type 27 (Flat): Used at a shallow 0°–15° angle; ideal for blending and finishing on flat surfaces.
Type 29 (Conical): Used at a 15°–35° angle; best for aggressive stock removal and edge grinding
Grit Selection:
Coarse (36–40): Heavy material removal and rough grinding.
Medium (60–80): Weld blending, deburring, and general-purpose finishing.
Fine (120+): Final surface refinement, cleaning, and preparation for paint.
Flap disc base：Fiberglass Base/Plastic Base/Nylon Base
Aluminum Oxide Flap Disc：Most common and budget-friendly; durable but dulls faster than premium grain, Ideal for mild steel, structural steel, ferrous metals, and general workshop use. Best suited for light to medium material removal, deburring, blending, and cleaning up welds on softer metals.
Calcine Flap disc: which is aluminum oxide that has undergone a heat treatment (calcination) process to enhance its durability and performance.
Harder and tougher than standard aluminum oxide. Offers a longer lifespan than basic aluminum oxide discs.
Sits in a mid-range price point between standard aluminum oxide and premium zirconia or ceramic.
Application Scope A great step up from standard aluminum oxide for improved life on mild steel.
Suitable for light fabrication and welding applications that need more durability than a basic disc can offer.
Zirconia Flap Disc：Lasts significantly longer than aluminum oxide flap disc.
Excellent for applications involving high heat and pressure.
Application Scope
Medium to Heavy Duty: Ideal for carbon steel, structural steel, stainless steel (Inox), and high-tensile metals.Industrial Fabrication: Used in automotive shops, shipyards, and foundries for aggressive grinding, heavy stock removal, and blending on harder materials. Stainless Steel (Inox): The preferred choice for applications requiring aggressive material removal on stainless steel
Ceramic Flap Disc：The longest lasting of the three types, offering exceptional value over time.
Extremely Aggressive: Provides a consistently high cut rate from start to finish, even with less pressure.
High Performance: Optimized for hard-to-grind materials.
Application Scope
Heavy Duty & Specialized Metals: Best suited for stainless steel, heat-sensitive metals, exotic alloys (titanium, nickel alloys), and hardened steel.
Robotic/Automated Grinding: Excellent for applications requiring consistent performance and automated material removal processes.
Maximum Productivity: Used in environments where speed and lifespan are prioritized for maximum efficiency.
Half-curved Flap Disc：
Curved flap disc suited for blending corner welds, thanks to the rounded flaps around the external part of the
backing pad. Its shape and the ceramic cloth make its life and cutting rate much higher than traditional flap
discs.
SIZE
FEATURES
- Aggressive Material Removal Coarse, sharp-edged silicon carbide grains remove material quickly.
- Durable & Long-lasting The thicker profile and dense arrangement of abrasive grains ensure durability.
- Longer service life compared to thinner cutting discs, even under pressure.
- Effective on a wide range of mineral-based materials. Can be used on concrete, bricks, pavers, tile adhesives, and some softer natural stones.
- More affordable than dedicated diamond cup wheels for general-purpose work. A practical and economical choice for general construction and maintenance tasks.
