Channel cutting thick plastic normally either turns out looking less than perfect with a standard router bit — or is just impossible. But Amana has a plastic router bit designed to cut, shape, and de-burr plastic all in one pass. The secret to good looking plastic cuts is fluted spiral cut of the bit.
This design “shaves” plastic instead of chewing it up like a standard wood bit. The bit also ejects plastic chips up or down, which gets them out of the active cutting area and reduces the chance that small chips will act as a high speed abrasive and melt/mar your cut.
The plastic router bits are available in 1/8”, 1/4”, and 3/16” diameters and are designed to cut plastic, wood, foam board, and solid surface materials — pretty much anything you might find in crafting or small project wood shops.
Street pricing starts at $15.
