COATED ABRASIVES 101
Coated abrasives are manufactured in “jumbo” rolls then cut into different shapes like:
- Flap Discs
- Flap Wheels & Specialties.
Abrasive grains such as aluminum oxide, silicon carbide, zirconia alumina, garnet & emery are bonded to a flexible substrate using adhesives.
Commonly used substrates include paper, cloth, fiber, & polyester films.
Grit sizes range from very coarse to ultra-fine.
Coated abrasives are used for surface-treatment & polishing applications in manufacturing sectors such as furniture & cabinet making, marine, automotive, welding, foundry, aerospace, & do-it-yourself markets.
Time Savings = Cost Savings!
Coated Abrasive Types & Common Uses
An overlap slotted disc is used for deburring and polishing radial holes and cylinder walls. The two-ply configuration cuts on the inward motion only, while the four or more ply configuration will cut on both the inward and outward motion. Both are furnished with a standard threaded quick-change eyelet.
Using fibre discs is still the most popular abrasives used on a grinder. With so much diversity available they are effective on a number of substrates like wood, metals, cast, fiberglass, stone. Fibre discs offer an outstanding cut, durability, and ease of use and are available in a huge range of grits. This makes them a great choice for fast removal right through to fine finishing.
Flap discs have an extended life, on average 15 to 20 times longer than fibre discs, reducing downtime. These versatile discs allow the user to grind and blend in a single step… streamlining the finishing process and increasing productivity. Flap discs are growing in popularity worldwide as they surpass the daily challenges that the metal fabricating and finishing industry face today.
Sanding discs are available in larger sizes for refinishing hardwood floors. Or leveling and finishing other types of flooring. These discs usually have a heavy paper backing or are made of abrasive screen. To ensure a consistent finish it is important to never skip more than one grit as you are working through the process.
Quick-change discs have a small thread or button making it quick & easy to change through grits. These discs are smaller and are used for shaping, weld removal, grinding and blending. They are also good for getting into the small areas you cannot reach with the angle grinder.
Slashed Assemblies usually consist of four strips of Silicon Carbide Waterproof Cloth material bound at one end with a canvas loop or kraft mount. The sandpaper has cut slits or slashes, so while the sandpaper is being used it will pull apart into soft fingers to provide a consistent finish on curved and profile pieces. You can load multiple assemblies into a polishing head. These assemblies come in different lengths and widths and grits, so if you do not see what you are looking for, we can probably make it.
Stickit discs are used on orbital sanders for a fast and clean cut when grinding, sanding and finishing surfaces. A variety of abrasive grains make these super effective when shaping or smoothing most surfaces. Available in standard (no holes) and dust-free versions.
Bore polishing abrasives are ideal for cleaning, deburring and polishing the interior diameters of cylinders, tubes and hydraulic fittings. The flaps automatically adjust to the inside diameter, polishing the entire surface with one pass. Bore Polishers are self-centering with a spring action design.
Cartridge rolls are used in the finishing and polishing of corners or tight spaces where larger diameter tools cannot reach. Great for high speed deburring and flash removal. Excellent for sanding and polishing channels, fillets, recesses, side walls, and bottoms of dead-end holes.
Diamond Hand Blocks are a flexible and versatile hand-held abrasive that optimizes the sharp cutting action of diamond mineral to grind and finish many materials, including chilled iron, granite, carbide, composites, non-ferrous metals, thermal spray coatings and exotic alloys.
Sanding rolls like shop rolls can be torn to size, wound around circular pieces or twisted to fit cylinders or folded to reach into corners. A very durable product that can be used on metal, wood or plastic. Another common use of for three to eight-inch-wide abrasive rolls is to replace the sandpaper on your Drum sander. If you are replacing the sandpaper on your drum, the easiest way is to trace the shape of the piece you are removing to ensure the starting angle is correct.
Abrasive sanding sheets are often used in hand sanding, either folded up or wrapped around a block, but there are also finishing sanders that will take a half or a third of sheet. With so many grans and grits available sanding sheets can be used to sand anything. Sheets can have a paper backing, cloth backing for more durability, or the abrasive can be on screen for a faster cut.
Hook and Loop or Velcro backed sanding discs are used on orbital sanders for a fast and clean cut when grinding, sanding and finishing surfaces. A variety of abrasive grains make these super effective when shaping or smoothing most surfaces. Available in standard (no holes) and dust-free versions. Velcro discs should be used if you need to change grits often as the Velcro is reusable.
