Find the right dies for your Oster Threader!

The tables below are to assist you in determining which Oster Symbol Dies are required for your Oster Threading Machine. Since several Oster Threading Machines may use multiple Oster Symbol Dies, you may need to visually inspect your Oster Dies to determine which specific Oster Symbol Dies are for your machine. Each Oster Die in a set is stamped or inscribed on one side with the Symbol for that set. For example several Oster Threading Machines may use either Symbol QUAD Oster Dies or Symbol 300 Oster Dies. If this is the case, you would then look for the marking on your Oster Dies for either QUAD or 300, and that will be the Oster Symbol Die required for your machine.
