61105 - PFERD 4-1/2 Inch SG INOX Grinding Wheel Type 27

PFERD 61105: The Specialist for Stainless Steel

For welders and fabricators seeking a grinding solution that combines speed, safety, and finish quality, the PFERD 61105 SG INOX Grinding Wheel is a top-tier choice. This 4-1/2" x 1/4" x 7/8" wheel features the specification A 30 N SG-INOX, indicating a specialized aluminum oxide formulation with a grit size of 30 and a hardness grade of N. This specific combination is engineered to provide a "soft" grinding feel, which means the abrasive grains break down at a controlled rate to constantly expose sharp new cutting edges. This self-sharpening action ensures that the wheel cuts aggressively throughout its life without glazing over, even on tough materials like stainless steel and high-temperature alloys.

The Type 27 (depressed center) geometry provides the rigidity needed for heavy weld removal and chamfering while allowing the operator to maintain a standard 30-degree grinding angle. PFERD has developed this wheel to offer maximum economic efficiency; the fast removal rate means less trigger time for the operator, reducing fatigue and increasing daily throughput. Furthermore, the cool cutting action significantly reduces the risk of thermal damage to the workpiece, which is a common issue when grinding stainless steel with inferior abrasives.

Safety and quality are paramount in the design of the PFERD 61105. It is manufactured without iron, sulfur, or chlorine contaminants, ensuring that it will not introduce rust-causing impurities into the weld zone. This makes it a safe and reliable tool for critical industries such as aerospace, chemical processing, and food and beverage equipment manufacturing. With its robust construction and superior abrasive technology, the PFERD SG INOX wheel stands out as a reliable workhorse for any industrial environment requiring heavy-duty metal removal.
