Abstract
The present invention provides a pin milling cutter formed by combining a cutter and an adapter to prevent errors in attaching a cutter to the adapter even when the cutter is similar but of a different type and even if the engagement section between the cutter and the adapter are the same. A mounting error prevention mechanism is provided on a main cutter unit and an adapter to prevent an erroneous combination of a cutter and adapter from fitting together normally. The mounting error prevention mechanism includes: a projection and a cavity corresponding to the main cutter unit and the adapter and providing a tapered fit; and a projection and a corresponding groove. The projection can be inserted into the groove only when the cutter and the adapter are combined correctly.
