Diablo's Steel Demon Flap Discs are the ultimate solution for grinding and polishing metal and stainless steel surfaces with unparalleled efficiency. Featuring the innovative X-LOCK system, these discs allow for quick, tool-free changes, saving you time and effort on the Job. The 60-grit (coarse) composition combined with the Type 29 conical shape provides up to 10X faster material removal compared to standard grinding wheels, making it ideal for aggressive stock removal. These discs not only grind but also polish simultaneously, leaving your workpiece with a smooth, shiny finish that enhances its appearance and performance. The versatile design is backwards compatible with both X-LOCK and 7/8" arbor angle grinders, ensuring seamless use across different tools. With a maximum RPM of 10,150, these discs are built for heavy-duty use, allowing you to tackle even the toughest grinding tasks. No extra parts are required to attach them to your X-LOCK grinder-simply snap them on or pull the lever to release, making your workflow faster and more efficient.
