Weiler Abrasives Group announced the expansion of its resin fiber discs (RFDs) offering to include five new products for varying performance requirements: Tiger Ceramic, Zirc and Aluminum, and Wolverine Zirc and Aluminum Oxide. These discs are designed to provide an aggressive cut rate and a smooth finish on tool steel, aluminum and any material in between. The products are ideal for heavy stock removal, edge chamfering, weld blending, grinding, and surface preparation and finishing.
Featuring advanced grain formulas, along with a design that minimizes loading, glazing and grain stripping, the new Tiger and Wolverine resin fiber discs include heavy-duty vulcanized fiber backing to withstand tough jobs. In addition to standard 7/8 arbor discs, a quick-change hub option reduces downtime and eliminates the need for tools and disc nuts.
As part of Weiler’s maximum performance line of RFDs, Tiger Ceramic features an advanced, self-sharpening ceramic grain that delivers greater stock removal with a finer scratch pattern, along with a superior life and cut rate, according to the company. A top coat grinds cool, reducing heat discoloration and loading. This disc is ideal for work on armored steel, stainless and tooled steel, Inconel and more, in applications requiring high removal rates.
Tiger Zirc and Aluminum are part of Weiler’s high performance line of RFDs. Tiger Zirc leverages a blend of shelf-sharpening zirconia-alumina and ceramic-alumina grains for fast cut rates, exceptional consistency and a long life. This makes them ideal for improving productivity and cost savings on light to heavy pressure grinding applications on materials such as steel, stainless steel and cast iron. Tiger Aluminum provides a non-loading solution for grinding aluminum and other non-ferrous metals. A top coating releases lubrication when grinding to reduce heat build-up and allow the metal to shed for higher cut rates, longer life and a superior finish.

- aluminum oxide
Aluminum oxide, also known as corundum, is used in grinding wheels. The chemical formula is Al2O3. Aluminum oxide is the base for ceramics, which are used in cutting tools for high-speed machining with light chip removal. Aluminum oxide is widely used as coating material applied to carbide substrates by chemical vapor deposition. Coated carbide inserts with Al2O3 layers withstand high cutting speeds, as well as abrasive and crater wear.
Shaft used for rotary support in machining applications. In grinding, the spindle for mounting the wheel; in milling and other cutting operations, the shaft for mounting the cutter.
1. Flexible portion of a bandsaw blade. 2. Support material behind the cutting edge of a tool. 3. Base material for coated abrasives.
Machining a bevel on a workpiece or tool; improves a tool’s entrance into the cut.
Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.
