The KGS 115mm Hybrid CN Diamond Flap Disc (Black, 120 Grit) with part number KGSFD82506 is a commercial-grade, medium-grit abrasive wheel engineered for rapid material removal, heavy deburring, and uniform beveling. Sitting perfectly between aggressive stock removal and fine polishing, this 120-grit black diamond disc replaces traditional rigid stone grinding wheels. It features an integrated pre-threaded adapter for instantaneous, secure mounting onto handheld angle grinders.
For fabricators looking to maximize concrete and masonry efficiency, premium heavy-duty equivalents like the SORMA Fastline LM Hybrid Flap Disc Range and dedicated edge-shaping options are available directly through Australia’s specialist trade supplier at Diamach.
Key Features & Benefits
• Aggressive Medium Grit: The 120-grit (Black color-coded) diamond matrix excels at clean edge grinding, chamfering, and face calibration.
• Anti-Vibration Engineering: Drastically reduces hand and arm vibration compared to heavy rigid cup wheels, lowering operator fatigue and preventing edge bounce.
• Universal Application: Formulated to process tough, brittle surfaces effortlessly, including natural stone (granite, marble), quartz, ceramics, engineered stone, and concrete.
• Wet or Dry Execution: Fully operational across dry edge-work and wet environments. Wet grinding is highly recommended to eliminate airborne crystalline silica dust and maximize disc lifespan.
Sourced directly via Diamach as an alternative ultra-aggressive option optimized for rapid, cost-effective profiling and edge chamfering.
Operation Tip
To secure a chipping-free profile on sensitive porcelain or quartz, operate your grinder at 8,000 RPM with light surface pressure rather than full speed.
