The Amana Spiral O Single Flute ZrN Coated Aluminum Cutting Up-Cut Mirror Finish Router Bit is made to be used only on CNC machines and routers with automatic feeding. Using the highest quality sub-micrograin carbide these bits have a special proprietary edge processing system featuring a super high polished cutting edge with a unique “mirror finish” resulting in clean cuts, less chance for chip re-welding, a superior surface finish and a longer tool life. Right hand helix right hand cut.

Specifically designed for a variety CNC machining applications and excellent for cutting:

  • ALPOLIC Copper Composite
  • Alucobond
  • Aluminum
  • Aluminum 5052
  • Aluminum 6061
  • Aluminum Alloys
  • Aluminum Composite
  • Aluminum Composite Panel (ACP)
  • Alupanel
  • Brass
  • Copper
  • Dibond
  • Durabond
  • e-panel
  • Etalbond
  • Fomex with Aluminum Face
  • Gold
  • Non-Ferrous Metals
  • Plastic
  • Silver
  • Solid Surface
  • Titanium Composite Material (TCM)
  • Wood

Ideal for industrial applications Amana spiral ‘O’ flute router bits are manufactured using innovative techniques and materials that yield superior results with each cut and help make aluminum projects less labor-intensive.

Benefits of Mirror-Finish:

  • Razor sharp cutting edge
  • Effortless chip removal
  • Helps prevent chip re-welding
  • Extends tool life
  • Exceptional cut quality
  • Dissipates heat well and prevents melting

Benefits of Zirconium Nitride (ZrN) Coating

  • Creates a harder and tougher cutting edge allows for a prolonged cutting edge life and helps to prevent the build-up of material in the flutes while cutting
  • Have the tendency to run/spin much faster than an uncoated tool
  • 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)
  • High flute volume supports high feed rates and chip loads
  • High aspect ratio for single pass deep-reach cutting

Warning: Never attempt to cut ferrous metals with these bits. Inspect cut quality adjust feed / speed accordingly. For optimal results and extended tool life use mist lubricant system or air cooling.


  • Diameter: 1/8"
  • Cutting Height: 1/4"
  • Shank: 1/4"
