CGW-Camel Grinding Wheels has expanded its existing line of flap discs with the introduction of trimmable Z3 flap discs. The new flap discs have a disc backing designed to trim down to expose flaps for extended working life, allowing for fewer disc changes and longer production times. The new U.S.-made, trimmable Z3 flap discs have a hybrid compact flap design that compresses and compacts flaps at a 4-degree angle for additional edge strength and 20 percent more material than regular Z3 flap discs. Manufactured from premium zirconia alumina grain and a strong polyester and cotton flap backing, the new discs are recommended for heavy-duty use and aggressive applications. The new flap discs are available in 4 1/2- and 5-inch diameters, with 7/8-inch arbor holes and 40, 60 and 80 grit sizes.
