27615 - Sait Challenger 3 Flexible Grinding Wheel 5-Inch Type 29 A36

Advanced Flexible Grinding Technology

The Sait Challenger 3 (SKU: 27615) represents a significant evolution in bonded abrasive technology. Designed as a semi-flexible grinding wheel, it bridges the performance gap between traditional rigid grinding wheels and resin fiber discs. This 5-inch wheel features a Type 29 depressed center profile, which provides a conical shape ideal for working at aggressive angles (typically 15 to 25 degrees) and contouring to curved surfaces. The wheel is manufactured with premium Aluminum Oxide grain in a coarse 36 grit (A36), ensuring rapid stock removal while maintaining a consistent finish.

Cool Cutting Open Pattern

One of the defining technical features of the Challenger 3 series is its proprietary surface pattern. The wheel face utilizes a raised "waffle" or open pattern design. This geometry serves two critical engineering functions: heat dissipation and swarf evacuation. By allowing air to circulate between the abrasive surface and the workpiece, the wheel grinds significantly cooler than solid bonded wheels. Furthermore, the voids in the pattern provide escape channels for debris, which virtually eliminates loading and clogging. This makes the Sait 27615 exceptionally effective on soft, non-ferrous metals like aluminum, which typically gum up standard abrasives.

Nuclear Industry Safe

Material purity is a priority for high-stakes industrial applications. The Sait Challenger 3 is formulated to be contaminant-free, containing less than 0.1% Iron (Fe), Sulfur (S), and Chlorine (Cl). This certification makes it safe for use in the nuclear industry and for fabrication environments where cross-contamination on stainless steel must be strictly avoided to prevent corrosion. The semi-flexible bond also absorbs vibration, reducing operator fatigue and noise levels compared to rigid wheels, resulting in a safer and more ergonomic grinding experience.
