RTC Diamond Flap Discs

RTC Diamond Flap Discs - Smooth, Controlled Edge Refinement 

RTC Diamond Flap Discs are engineered for pros who want grinding power without sacrificing finesse. Instead of the harsh, sometimes unpredictable bite of a blade, flap discs use layered diamond-abrasive flaps that make contact gradually, delivering a smoother, more controlled grind. This helps prevent gouging and gives you a refined, even edge that’s easier to polish or finish.

They’re perfect for prepping miters, softening cut edges, truing up factory sides, or removing small imperfections on dense porcelain. The disc runs cooler than traditional grinding wheels, extending tool life and reducing the chance of burning or micro-chipping the edge.

Whether you're working on LFT, rectified tile, stone, or decorative pieces, RTC’s flap discs give you the accuracy and surface quality needed for premium, finish-grade work.
