The CGW 42701 7" X 7/8" Type 27 36-Grit Z3 Zirconia Flap Disc is engineered for aggressive stock removal on steel surfaces. This flap disc combines premium zirconia-alumina grain with a poly/cotton backing to balance durability and a refined finish. The zirconia concentration enables faster material removal while the active grinding aid helps maintain cooler cutting during heavy-duty, high-pressure operations. The Type 27 profile is designed to provide a favorable grinding angle for grinding, deburring, and finishing tasks on flat or slightly curved metal workpieces, making it suitable for applications that require both stock removal and a smoother final surface after blending.
Key construction details include a 7-inch diameter with a 7/8-inch arbor/shank size to fit common right-angle grinders. The 36-grit rating indicates a coarse grain structure appropriate for rapid material removal, while the Z3 designation highlights a balance between aggressive grinding and disc life. This product is packaged as an individual disc, with a box quantity of 10, which can influence stocking and project planning for shops with higher throughput.
Users should consider the disc’s intended use when selecting assortments for steel fabrication, maintenance, or repair tasks. For best results, operate at compatible RPMs and apply moderate pressure to leverage the cooling and cutting characteristics of the active grinding aid, reducing heat buildup during prolonged grinding sessions. Compatibility notes: designed for 7" diameter grinders and standard 7/8" arbors, ensure the tool configuration matches equipment before installation, and replace discs when wear reduces effectiveness or balance is compromised.
