Amana - 51404-K - 1/4" Plastic Cutting

Amana - 51404-K - 1/4" Plastic Cutting

51404-K - Plastic Cutting (Solid Carbide, Spiral 'O' Flute, Up-Cut)

  • Shank: 1/4"
  • Diameter: 1/4"
  • Cutting Length: 3/4"
  • Overall Length: 2"
  • Flutes: 1 Flute

To be used only on CNC machines and routers with automatic feeding.

Produce super clean, smooth cuts especially in acrylic materials (Plexiglas® Lucite®) other plastics and wood. Bits are made according to strict tolerances from an exclusive carbide grade and polished to a mirror finish using Amana’s unique process. Designed to eject chips up. Ideal for industrial applications and CNC machines. Right hand helix right hand cut.

*Corrugated Plastics such as Correx refers to a wide range of extruded twinwall plastic-sheet products produced from high-impact Polypropylene resin with a similar make-up to corrugated fiberboard. They are used in a variety of applications including boat building packaging signage outdoor advertising and the production of pet cages.

***Gatorfoam® Foam Board a polystyrene foam board bonded between two layers of Luxcell® wood-fiber veneer.

****Decorative high-pressure compact laminate (HPL) with an integral surface.

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

Router collet reduce­­r RB-102 (1/4 to 1/8) available for 1/8 shank bits.

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.

  • nACo coating is a micro-thin ceramic coating which enables the tool's cutting edge to retain crucial sharpness and lubricity. This provides longevity and produces cutting results of the highest quality.
  • Coating prevents high heat and oxidation which is detrimental to cutting tool performance.
  • Multi-colored hues, while attractive, will dissipate upon use and yet coating will remain fully effective.
  • nACo offers approximately 4,500 Vickers for impressive solid hardness on cutting areas of the tool, for an increase up to 2.5 times compared to uncoated bits.

Note: Blue based color dissipates immediately upon use. nACo® nanocomposite coating will not wear off.

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