The CGW 31175 is a 4-1/2 inch diameter, 5/8-11 thread-on Type 27 zirconia flap disc designed for grinding and finishing applications on metal surfaces. This disc uses a premium blend of zirconia and aluminum oxide grains with a grinding aid to balance material removal with heat control, making it suitable for heat-sensitive operations and particularly effective on stainless steel where welds and polished joins can be challenging. The 80-grit structure provides a coarser finish that supports rapid material removal while maintaining a reasonable surface quality for subsequent steps.
Constructed to operate at up to 13,300 RPM, the disc features a Type 27 profile, which is designed for flat and angled grinding angles to reach into contours and weld seams. The combination of zirconia abrasive grains and the specified geometry helps improve life under demanding metalworking tasks by resisting grain wear and maintaining cut efficiency. The product is packaged as individual units with a box quantity of 10, offering a straightforward stocking solution for shop or field use.
This flap disc is compatible with standard 4-1/2 inch grinders that accept 5/8-11 arbor attachments. When selecting a disc for stainless steel and heat-sensitive workflows, consider the grain blend and grit level to balance metal removal rate with surface finish. Proper wheel mounting, torque, and tool speed are important to maintain disc integrity and achieve consistent results across multiple passes.
