Blue-Kote II

The Vented High Density Flap Disc is designed to tackle the toughest surface finishing and blending tasks with precision and efficiency. Featuring a heavy-duty vented construction, this tool stays cool during high-speed, high-pressure operations, extending its lifespan and maintaining consistency. Its zirconium grain delivers superior stock removal, while the 40% quieter performance and reduced vibration make long jobs more comfortable. The innovative stroboscopic effect ensures you can clearly see the working area, even during operation, for enhanced accuracy. Ideal for ferrous metals, stainless steel, aluminum, and more, it’s perfect for removing rust, smoothing imperfections, or blending curves in metal fabrication or auto body repair projects.
• Less Vibration - last 30% to 40% longer than standard flap discs
• Lock nut doesn't get in the way of cutting
• For use on 4-1/2", 5" and 7" right-angle grinders
Suitable for
• Ferrous metals

CAUTION: Protect yourself from product breakage and flying particles. Always wear eye and face protection, and make sure machine guards are in place. Comply with ANSI B7.1.
