Amana tool 46096-Z SC CNC End Mil Point Diamond Pattern 1/8 D x 3/4 CH x 1/4 SHK x 2 Inch Long Composite Cutting ZrN Coated Router Bit

This bits are 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: CompositeFiberglassFiberglass PCB BoardGlass Fiber Reinforced Polymer - Plastic Materials (GFR)Glass Reinforced Plastic (GRP)G10G11PhenolicsPhenolic "Garolite" G-7Benefits of ZrN Coating Zirconium Nitride (ZrN) coated bits have the ability to run and/or be spun much faster than an uncoated tools.ZrN coating creates a harder and tougher cutting ceramic over carbide edge, allowing for a prolonged cutting edge life and helps to prevent the build-up/galling of material in the flutes while cutting.High flute volume supports high feed rates and chip loadsHigh aspect ratio for single pass deep-reach cuttingCreates incredibly precise detail workMirror finish polished flute, up-spiral cutting edge for superior chip ejectionFlute geometry optimized for cutting sign foam, sign board, hardwoods, thermoplastics and phenolic compositesOptimized flute geometry and low Total Indicated Runout (TIR) guarantees clean cuts, essentially eliminates sanding and reduces chatter (where the machine or work piece vibrates) under high chip loads when used with low TIR spindles.
