35107 - PFERD A4 Mounted Point 30 Grit INOX Grade N

Heavy-Duty A4 Grinding Stone for Die Grinders

Tackle tough stainless steel jobs with the PFERD 35107 A4 Mounted Point. Designed for professional welders and fabricators, this abrasive point is engineered to solve the common challenges associated with grinding stainless steel, such as heat buildup and glazing. The secret lies in the "Grade N" formulation—a specialized resin bond paired with high-quality aluminum oxide grain. This combination ensures the stone cuts freely and coolly, significantly reducing the risk of heat tinting or blueing your workpiece. With a coarse 30 grit texture, this tool is built for aggressive material removal, allowing you to grind down welds and burrs quickly and efficiently.

The A4 shape is a staple in any fabricator's toolbox. Its cylindrical profile is perfect for working on edges, beveling, and smoothing out rough contours inside pipes or structural channels. The 1/4-inch shank is universally compatible with air and electric die grinders, providing a secure grip that prevents slippage under load. Because it is resin-bonded, this mounted point offers a slightly softer grinding action compared to vitrified bonds, which helps in achieving a smoother surface finish without gouging the base metal. It is tough enough to handle edge grinding applications where harder bonds might chip or shatter.

When working with expensive materials like stainless steel, using the right abrasive is crucial to avoid cross-contamination and rework. PFERD's INOX rating guarantees that this product is free from ferrous, chlorinated, and sulfurous fillers that could compromise the corrosion resistance of your stainless steel projects. Add the PFERD 35107 to your abrasive arsenal for a reliable, long-lasting grinding solution that helps you produce cleaner, professional-grade welds every time.
