Annular Cutter set (7/16-"1-1/16"): https://amzn.to/38s627n Annular Cutter set (1"-2"): https://amzn.to/3eGQU7o Adam recently picked up a set of these annular cutters on the recommendation of his good friend John Knoll, and their efficiency in cutting large holes through aluminum blew Adam's mind. Adam demonstrates how they work compared with a normal milling bit, and explains why their design allows them to cut so smoothly. As always, go slowly with a tool like this and use lots of cooling fluid! Shot by Adam Savage Disclaimer: Tested may earn an affiliate commission when you buy through the links here.
