Flap Discs
Flap discs combine grinding and finishing in one. They are versatile and can be used for both metal and wood, providing a smoother finish than standard grinding discs. These are constructed with multiple overlapping cloth-backed abrasive flaps that fan out from a central hub. These flaps wear away during use, continually exposing fresh abrasive material. They come in various grits and sizes to cater to different tasks.
Uses of flap discs:
- Surface Blending
- Finishing
- Deburring
- Stock Removal
- Contoured Surface Grinding
Diamond Cutting Discs
Diamond cutting discs feature a metal core with diamond-embedded segments or a continuous rim of diamonds. These discs are ideal for precise and clean cuts in hard materials like concrete, stone, tile, and ceramics. They offer long-lasting cutting performance.
Uses of diamond cutting discs:
- Concrete Cutting
- Tile Cutting
- Masonry Work
- Stone Cutting
- Granite Cutting
Wire Brushes
Wire brush discs are used for removing rust, paint, and corrosion from metal surfaces. They come in different bristle types, including crimped and knotted. These typically consist of metal wires or abrasive nylon bristles. They are mounted on a disc or wheel and are used for various surface preparation and cleaning tasks.
Uses of wire brushes:
- Rust Removal
- Paint Stripping
- Weld Cleaning
- Surface Deburring
- Removing Scale and Corrosion
Sanding Discs
Sanding discs for angle grinders are typically abrasive discs used for smoothing, finishing, and shaping various materials. They are made with abrasive particles bonded to a backing material, which can be paper, cloth, or other substrates. They come in different grits, allowing for both rough and fine sanding.
Uses of sanding discs:
- Smoothing Wood Surfaces
- Removing Paint or Varnish
- Shaping and Sanding Metal
- Preparing Surfaces for Painting or Coating
- Polishing and Finishing Applications
Polishing Pads
Polishing pads are designed to enhance the finish and shine of various materials. They are often used with polishing compounds for metal and stone. These pads are typically made with different types of abrasive or polishing materials, including foam, felt, or cloth, depending on the specific polishing task.
Uses of polishing pads:
- Polishing Metal Surfaces to a High Shine
- Restoring the Gloss of Painted Surfaces
- Buffing and Polishing Automotive Finishes
- Enhancing the Luster of Stone and Concrete
- Polishing and Finishing Applications in Metalworking and Woodworking
Carbide Discs
Carbide discs are designed for aggressive material removal, making them suitable for cutting and grinding hard materials like concrete, stone, and masonry. They are constructed with carbide-tipped teeth, making them incredibly durable and suitable for cutting through hard and abrasive materials.
Uses of carbide discs:
- Cutting through hard metals, including steel, stainless steel, and cast iron.
- Efficiently slicing through dense materials like ceramic, porcelain, and hard tiles.
- Demolition work involving concrete, masonry, and stone.
- Precise shaping and notching of various hard materials.
- Removing rust, scale, and paint from metal surfaces.
Fiber Discs
Fiber discs are similar to grinding discs but are reinforced with fiberglass for added durability. They are used for heavy material removal and are suitable for metal and wood. They are constructed with a reinforced fiber backing and abrasive grains embedded in resin. Fibre discs are known for their flexibility and versatility.
Uses of fiber discs:
- Surface preparation, such as rust and paint removal.
- Smoothing weld seams and rough surfaces.
- Deburring and blending sharp edges.
- Sanding and finishing various materials, including metal, wood, and plastic.
- Polishing and buffing when used with appropriate polishing compounds
Masonry Discs
These discs are specifically designed for cutting and grinding masonry materials like concrete and brick. They are durable and provide efficient cutting.
Uses of masonry discs:
- Cutting concrete slabs or blocks.
- Creating openings for pipes or electrical boxes in concrete walls.
- Shaping or notching bricks for precise fits in construction projects.
- Removing mortar from bricks or stones.
- Smoothing or leveling concrete surfaces.
- General masonry tasks where abrasive cutting or grinding is required.
Wood Carving Discs
Wood carving discs for angle grinders are specialized attachments designed for carving, shaping, and sculpting wood. They typically feature a series of sharp teeth or blades that allow for controlled wood removal and precise wood carving.
Uses of wood carving discs:
- Carving intricate designs or patterns into wooden surfaces.
- Shaping and sculpting wood for woodworking projects.
- Removing excess material quickly while maintaining precision.
- Carving details on wooden furniture or decorative pieces.
