United Abrasives-SAIT 22021, Cutting Wheel, 4-1/2" x .045" x 7/8" Type-27 A60S, 50/box
A60S - General Purpose
• So unique it has a patent
• Thin .045 width
• Special aluminum oxide grain
• Hard bond for extremely long life
• Fast, burr-free cutting
Ferrous and/or non-ferrous metals (iron, steel, welds, etc.)
Key Advantages
- Increased Safety: Wheels are externally reinforced with extra layers of fiberglass to provide high structural integrity and shatter resistance during high-speed thin cutting.
- Innovated Design Origin: They pioneered the patented Type 27/Type 42 depressed-center wheel design, which improves operator visibility and allows for flush cutting.
- Fast and Clean Cuts: Thin profiles (such as .045" or .035") reduce kerf width for rapid, burr-free cuts on steel, stainless steel, and aluminum.
- Advanced Grain Formulations: Premium lines utilize self-sharpening ceramic aluminum oxide or proprietary zirconium grains that stay cool and extend wheel life.
- Reduced Material Waste: Thin high-speed designs remove less base material per cut compared to thick grinding or pipeline wheels
