CGW 31174 4-1/2" X 5/8"-11 Type 27 60-Grit ZS Zirconia Flap Disc

The CGW 31174 4-1/2" x 5/8-11 Type 27 60-Grit ZS Zirconia Flap Disc is designed to provide efficient material removal and a smooth finish on metal surfaces, with a focus on heat-sensitive applications. This flap disc combines zirconia and aluminum oxide grains to deliver a balanced grinding action, helping to maintain performance while mitigating heat buildup during use. The 60-grit size offers a medium-abrasive texture suitable for preparing stainless steel and other alloys where controlled material removal and surface quality are important. The integrated grinding aid assists in reducing heat generation and preventing premature loading of the abrasive, which can extend disc life and improve consistency on demanding jobs.

Key construction features include a 4-1/2 inch diameter to fit common angle grinders and a 5/8-11 arbor size, Type 27 profile designed for surface grinding with a flatter contact face. The rated operating speed of up to 13,300 RPM supports efficient metal finishing tasks while helping users select compatible equipment and maintain safe operating practices. This product is packaged individually or in a box quantity of 10, making it suitable for both single-job use and bulk purchasing. While zirconia blends are known for versatile performance, the actual results depend on workpiece material, thickness, and grinder settings; users should follow standard safety protocols and dress the wheel appropriately for best results.

This flap disc is intended for metalworking tasks where both abrasion efficiency and control are required, such as deburring, blending welds, and light shaping on stainless steel. Ensure compatibility with your grinder’s arbor and guard setup, and verify that the Type 27 configuration aligns with the intended surface contour. Proper selection of grit and backing material, along with appropriate RPM adherence, contributes to consistent results and helps minimize wear on the disc during use.
