Amana Tool Solid Carbide CNC Spektra™ Extreme Tool Life Coated Foam Up-Cut Cutting Square End Spiral 1/4 Dia x 2-1/4 x 1/4 Shank x 4 Inch Long Router Bit

Thank you for shopping with us!

Ensure your foam projects are milled with unparalleled accuracy detail and clarity. Achieve both precision and depth for foam carving and milling applications. Provides deeper cuts and larger slices with fewer passes in thick materials, resulting in improved productivity and less assembly. The upcut spiral ejects chips away from the workpiece.

Specifically designed for milling:

• Polyurethane Foam
• Expanded Polystyrene (EPS)
• Polyethylene Foam
• Extruded Polystyrene Foam (XPS)
• Crosslinked Polyethylene Foam (XLPE)
• Ethafoam**
• Ethylene-vinyl Acetate Foam (EVA)
• Expanded Polypropylene (EPP)*
• Flexible Polyurethane Foam (FPF)
• Fomex®
• High Density Urethane (HUD Board)
• PALFOAM™
• Polycarbonate (Lexan™)†
• Polylam**

*Expanded polypropylene (EPP) is a foam form of polypropylene.
**Ethafoam Polyethylene and Polylam are durable flexible closed-cell foams with excellent memory.
†Recommendation: Use the slowest suggested feed rates and the shortest bits necessary for cutting and routing Lexan™.


For thick material with upcut chip removal. For 2D & 3D CNC routing applications.

Our Spektra™ bits feature a nACo® nanocomposite coating with an extreme nanohardness and heat resistance. With a brilliant distinctively-tinted coloring nACo provides additional improvements in four critical aspects of router tooling.
