The CGW 42104 4" x 5/8" Type 27 60-Grit Zirconia Flap Disc is designed for aggressive material removal on steel surfaces. It combines premium zirconia alumina grain with a durable poly/cotton backing to balance stock removal with a reasonable finish. The zirconia concentration is intended to enhance abrasion efficiency, while the active grinding aid helps maintain cooler cutting action under light pressure, potentially reducing heat buildup during extended grinding sessions.
Constructed as a Type 27 disc, this product is tailored for off-angle grinding to help approach contoured or irregular surfaces more effectively. The 60-grit specification offers a relatively aggressive finish suitable for deburring, rust removal, and initial surface preparation prior to finishing steps. The disc is sized for a 4-inch wheel diameter with a 5/8-11 arbor, compatible with standard angle grinders rated for that size and thread.
Practical considerations include using light-to-moderate pressure to leverage the cooling aid and avoid glazing the flap. For best results, ensure proper wheel mounting and verify grinder RPM compatibility with the product’s 15,300 RPM rating. Packaging lists the standard quantity per box and per order, which helps with stocking and reordering for facilities that perform routine metal finishing tasks.
