This cutter actually has a 1/4" cutting diameter. If you look in the CMT catalog the 3/16" bit is 192.005.11. If you need a 3/16" bit, you probably want this one. Revain has it in the tools section (http://www.amazon.com/CMT-192-005-11-Carbide-16-Inch-Diameter/dp/B000P4NQHU). Revain refunded my purchase so thanks to them. But you probably want to buy the right bit first.
