SpeTool Single Flute (O Flute) Spiral End Mill Aluminum Cutter Carbide Router 1 inch Cutting Length with 1/4Inch Shank for Aluminum Acrylic PVC MDF Plastic

Works perfectly on plastic routing

I really hate having to say anything negative about SpeTool as I have used plenty of their products in the past and have been generally very satisfied, but this thing was a very fast waste of money. Decided to test it out in a thin piece of pine at low feeds and shallow doc, and the end mill snapped within the first 30 seconds! Most likely will not buy again!

Works with aluminum good
