When routing plastic materials you will be hard pressed to find a better collection of router bits other than Amana Tool®’s solid carbide spiral ‘O’ flute plastic-cutting router bits.

This series of bits are formed from a special long-lasting “Amana-Exclusive” carbide grade ensuring long tool life and high quality of cut.

Standards are set high for these router bits: there is a very high tolerance grinding for accuracy and the unique carbide polishing process results in a ‘Mirror-Finish’ on the tools. While holding these router bits in your hand, the polished finish looks more like a work of art rather than a tool designed for routing plastics.

Plastic are often used for signs in bars, restaurants, stores, movie theatres, offices and more. Signs are used to convey all sorts of information and play an important part in our society.

As a starting point, plastics may be placed into two general categories: flexible and rigid. The tools of choice for flexible plastic generally involve the use of single “O” flute tools, which are available in straight or spiral flute configurations. When it comes to creating signs, whether of plastic, wood, aluminum or foam, it's important to have the right cutting tools to create the best-finished product the first time.

Amana’s solid carbide spiral “O” flute router bits are manufactured in widths ranging from 1/8” to 1/4" in diameter making them excellent for creating signs and displays in a large variety of materials such as:

  • Acrylonitrile Butadiene Styrene (ABS)
  • Acetal Acrylic Alupanel®
  • Corrugated polypropolyene
  • Gatorboard
  • High Density Polyethylene (HDPE)
  • Lucite
  • Nylon
  • Polyethylene (PE)
  • Polyethylene Terephthalate (PTE)
  • Plastic
  • Plexiglass
  • Solid Surfaces
  • Ultra High Molecular Weight Polyethylene (UHMW)
  • Wood

These bits will fit most CNC machines, other automatic routers as well as hand-held and table-mounted portable routers. Just like all router bits by Amana, they feature outstanding tool longevity, a tendency to stay sharper, mirror like carbide finish, excellent carbide brazing and most importantly: quality of cut.

They are available as up-cut spirals, which clear the chips fast and provide a clean bottom surface, and as down-cut spirals, which provides a clean top surface in your material. The “O” flute design provides cooler cuts to help avoid melting in plastics.

The “Mirror-Finish” single flute allows for easier chip evacuation and a sharper cutting edge that results in a better edge finish on a variety of plastics.
