A hole saw arbor, also known as a mandrel, connects a drill chuck to the actual saw itself. As a result, a high-quality arbor is important in making sure you get cleanly cut holes each time. To choose the right arbor, you need to look at the compatibility of the shank size and drill chuck size. 3/8" and 1/2" are the most common although some use a 1/4" diameter. The shape of the shank will also influence how secure the arbor is in the drill. Flat and hex-shaped shanks are the best to keep the arbor secure in jaw-like drill chucks.
