Grinding Wheels' High Cutting Rates ReduceTtotal Cost

Lawson’s Tuff-Grit Zirconium Grain Premium Grinding Wheels provide the optimal balance of material removal and wheel life. The longest-lasting, fastest-cutting abrasive is especially effective for hard-to-grind applications like stainless steel weldments, nickel alloys and ferrous metals.

  • Premium zirconium aluminum oxide grain is designed to provide ultimate performance over a wide range of applications
  • High cutting rates reduce total cost
  • Improved operator efficiency – no bouncing or spalling
  • Efficient grinding all the way down to a minimum stud for longest life
  • Outlast standard aluminum oxide discs 3-to-1
  • Type 27 wheel available in 4”, 4 1/2”, 5” 7” and 9” diameters

Related Glossary Terms

  • abrasive


    Substance used for grinding, honing, lapping, superfinishing and polishing. Examples include garnet, emery, corundum, silicon carbide, cubic boron nitride and diamond in various grit sizes.

  • alloys


    Substances having metallic properties and being composed of two or more chemical elements of which at least one is a metal.

  • aluminum oxide

    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.

  • grinding


    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.
