A rotary milling cutter has a cutter body mountable on an adapter. A first side of the adapter is provided with circumferentially arranged drive pins centered about a centrally positioned, conically tapered male locating member. A first side of the cutter body is provided with circumferentially arranged drive grooves centered about a centrally positioned, conically tapered female locating member. The drive pins have a base portion connected to a head portion while the drive grooves have an insertion portion connected to a retaining portion. During assembly, the first side of cutter body and the first side of the adapter are first moved into an initial mating position in which the drive pins enter the insertion portions of the drive grooves and the male locating member enters the female locating member. The cutter body is then rotated relative to the adapter such that the drive pins enter the retaining portions of the grooves. With the adapter retained in an inverted position with its drive pins extending vertically downward, the cutter body may thus be supported by the heads of the drive pins. A center bolt normally resident in a throughbore of the cutter body is then screwed into a threaded bore formed in the male locating member of the adapter.

Disclosed is a &ldquo;nest&rdquo; or seating element for tangentially-mounted &ldquo;on-edge&rdquo; cutting inserts for face mills which shares a peripheral pocket of the face mill with the cutting insert, and which facilitates the adjustment of the cutting insert it supports by virtue of its resilience in the axial direction of the face mill.

Adjustable insert seat

The cutting fluid distribution system disclosed is one in which the cutting fluid passages which carry the cutting fluid from a pressurized source to the cutting bits of a rotary milling cutter are incorporated into the cutter in a way to be formed in large part by the mere assembly of the constituent elements of the cutter.
