Amana Tool 46097 Solid Carbide Spiral 1/4 Dia x 3/4 Cut Height x 1/4 Shank x 2-1/2 Inch Long Composite, Fiberglass & Phenolic Cutting ZrN Coated Down-Cut Router Bit

*Coroplast® is soft plastic cardboard made with super soft, super flexible PVC.

Recommendation: Use the slowest suggested feed rates and the shortest bits necessary for cutting and routing Lexan™

• 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 loads
• High aspect ratio for single pass deep-reach cutting
• Creates incredibly precise detail work
• Mirror finish polished flute, up-spiral cutting edge for superior chip ejection
• Flute geometry optimized for cutting sign foam, sign board, hardwoods, thermoplastics and phenolic composites
• Optimized 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.
