Abstract
Reaming tool includes a head and a detachable cutting insert fixed in a seat. The seat includes radial, tangential, and axial support surfaces, while the cutting insert has a mirror-symmetrical polyhedron shape comprising six limiting surfaces, viz. two chip surfaces and at least two clearance surfaces, a number of alternately usable, identical cutting edges formed in transitions between the chip and clearance surfaces. A female- or male-like securing means co-operates with a complementary, male- or female-like securing means in the seat, more precisely in an inactive, contactless state as long as the cutting insert is held pressed by the cutting forces against the axial support surface. The securing means is activatable when the cutting insert is unintentionally distanced from the axial support surface against the action of a clamping member. Tool head and reaming insert for the tool are disclosed.
