Abstract
Reaming tool includes a head and one or more detachable cutting inserts fixed in seats. 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 four clearance surfaces, a number of alternately usable identical cutting edges formed in the transitions between the chip and clearance surfaces. The cutting insert has a rhombic cross-sectional shape with four clearance surfaces, which meet each other in pairs at obtuse angles in two opposite corners, and which, along each individual chip surface, form two cutting edges alternately usable by indexing the cutting insert. The seat additionally includes a slope surface forming an obtuse angle with the radial support surface, suitably of the same magnitude as the obtuse angle between the clearance surfaces of the cutting insert. Tool head and reaming insert for the tool are disclosed.
