This bit is designed especially for cutting fiberglass, fiberglass PCB board, composites, phenolic and other highly abrasive materials. Works well on epoxies made with carbon, glass and composite materials. The up-cut/down-cut diamond pattern cutting edges effectively grinds through the material evenly in all directions. Excellent for cutting: Composites Fiberglass Fiberglass PCB Board Fiber Reinforced Plastic (FRP) Glass Fiber Reinforced Polymer - Plastic Materials (GFR) Glass Reinforced Plastic (GRP) G10 G11 Phenolic Phenolic “Garolite” G-7 Maximum RPM: 28,000
