If you’ve ever worked plastic with woodworking tools, you’ve probably noticed that the chips usually melt to the side of the cut, or chip welding as it’s commonly called. Not only does cleaning it up add more work, but you don’t get a nice crisp edge.
I discovered that several of the blades designed to cut plastic without melting all seem to have the same features: They use a modified triple chip grind and the carbide teeth have a -2ยบ hook angle. It turns out this is not a coincidence. Both the moderately priced A.G.E. and the inexpensive Timberline brands are also made by Amana Tool.
The Timberline blade is 10″ in diameter and will run you about $20, the A.G.E blades come in sizes ranging from 7-1/4″ to 14″ and run anywhere from $50 to $160, and the Amana blades come in sizes ranging from 8″ to 16″ and run between $100 and $270.
