The Amana Tool 51511-K CNC Spektra Coated SC Spiral O Single Flute, Plastic Cutting 1/8 D x 1/2 CH x 1/4 SHK x 2 Inch Long Down-Cut Router Bit with Mirror Finishuses a spiral down cut design in order to cut the plastic at a more efficient angle and guide the chips downward of the cutting profile to remove chips.
The Amana Tool 43500-K SC Spektra Extreme Tool Life Coated Single O Flute, Plastic Cutting 1/8 D x 1/2 CH x 1/4 SHK x 2 Inch Long Router Bit uses a older straight flute design which cuts the material at a more blunt 0 degree angle and allows for removal of the material, but with not as good of a finish in comparison to a spiral cutter.
For finish quality, the Amana Tool 51511-K would provide a cleaner cut.
