Flap Disc DFD-C100X1672
High-performance 4" calcined aluminum oxide flap disc engineered for aggressive metal grinding and weld blending. The heat-treated abrasive grains deliver superior durability and continuous self-sharpening action, outlasting standard aluminum oxide discs in heavy-duty fabrication environments.
Key Features
- Premium Calcined Aluminum Oxide Grains
- Aggressive Stock Removal (P40-P120)
- Durable Fiberglass Backing Plate
- 72-Flap Reliable Construction
Application Scenarios
- Aggressive Weld Blending and Edge Grinding
Calcined aluminum oxide grains are heat-treated for increased hardness and toughness. When used with high-speed angle grinders, these discs aggressively level weld seams, chamfer metal edges, and remove heavy mill scale without premature grain dulling. - Continuous Self-Sharpening Performance
Unlike standard bonded abrasives that glaze over, the layered flap design continuously exposes fresh, sharp calcined grains as the disc wears. This self-sharpening action maintains a consistent cut rate and surface finish throughout the long service life of the disc. - Rust Removal and Surface Preparation
Ideal for automotive body repair and industrial maintenance, the 100mm disc quickly strips rust, thick paint layers, and corrosion from steel and iron substrates, preparing the surface for priming or welding. - High-Volume Consumable for Fabrication Supply
Metal fabrication shops, shipyards, and structural steel contractors consume flap discs daily. The calcined abrasive offers distributors a compelling "cost per cut" value proposition to replace standard aluminum oxide alternatives on shop floors.
