The present invention relates to a cutting tool comprising a tool holder body (14;14) having a shank portion (12;12) and a head portion (13;13). The head portion has an insert seat (15;15), wherein a cutting insert (20;20) is detachably mounted by means of a locking member (18;18). The seat comprises at least one bottom surface (16;16) on which the cutting insert rests. A coolant conveying member (29;29) is integral with the tool holder body. A normal (N;N) to the at least one bottom surface (16;16) intersects the coolant conveying member, such that the coolant conveying member at least partially covers the cutting insert.

Flintstone2020 aims to provide a perspective for the replacement of two important CRMs tungsten (W) and cobalt (Co) which are the main constituents for two important classes of hard materials (cemented carbides/WC-Co, and PCD/diamond-Co), by developing innovative alternative solutions for tooling operating under extreme conditions. Fundamental knowledge on mechanical properties and wear of different tools, gained in machining tests and dedicated experiments from WP1 is passed onto the respective WPs. WP2 will experiment on small samples with 3-9 mm for testing the fundamental behavior of new B-X phases and particularly as a feedback for binder matrix improvement. In WP3 samples (12 mm ) will be investigated from individual HPHT runs for characterization and testing to guide high pressure sintering process optimization. The HPHT process and the samples produced are then upscaled to the industrial mass production level in WP4. In WP5, demonstrator cutting tools from full size HPHT synthesis test runs will be prepared via laser cutting and consecutive macro- and microshaping of tool geometry within WP5. In WP6 aspects of environmental benefits in the total life cycle of the superhard materials will be investigated, including health and safety aspects. WP7 will focus on exploitation and dissemination.
