A method of making a super-hard article comprising a super-hard structure (14) bonded to a substrate (18), the super-hard structure comprising a sintered plurality of super-hard grains. The method includes providing raw material powder suitable for sintering the super-hard structure. The raw material powder is combined with organic binder material in a liquid medium to form paste. The content of the raw material powder is more than 60 and less than 85 mass per cent of the paste and the composition of the paste is such that it has a shear rate of at most 25 inverse second (s-.sup.1). A substrate assembly is provided, which comprises the substrate, having a formation surface area configured for forming a boundary of the super-hard structure, the substrate comprising a recess coterminous with the formation surface area. The paste is extruded into contact with the formation surface area to provide a paste assembly. The paste assembly is heat treated to remove the binder material and provide a pre-sinter assembly. The pre-sinter assembly is subjected to a pressure and temperature sufficient to sinter the raw material powder and transform it into the super-hard structure bonded to the substrate at a boundary coterminous with the formation surface area. The super-hard material is diamond or cubic boron nitride.

A method of making a construction comprising a polycrystalline super-hard structure joined to a side surface of an elongate substrate. The method includes: providing a vessel configured for an ultra-high pressure, high temperature furnace, the vessel having an elongate cavity for containing a pre-sinter assembly and defining a longitudinal axis, the cavity having opposite ends connected by a cavity wall. The pre-sinter assembly comprises the substrate, an aggregation comprising a plurality of super-hard grains arranged over at least a part of the side surface of the substrate, and a spacer structure configured for spacing the substrate apart from the cavity wall. The spacer structure comprises material having a Young's modulus of at least 300 GPa. The method further includes inserting the pre-sinter assembly into the cavity, the substrate being substantially longitudinally aligned and the spacer structure arranged between the side surface of the substrate and the cavity wall; applying a force to the pre-sinter assembly and heating it to a temperature, the force being sufficient to generate a pressure within the vessel for sintering the aggregation at the temperature, and providing the construction.

A micro end mill includes a shank made of a first material and a cutting tip made of a second, different material that is bonded to the shank. The first material can be, for example, carbide or high speed steel (HSS), and the second material can be, for example, cubic boron nitride (CBN), polycrystalline cubic boron nitride (PCBN), ceramic or polycrystalline diamond (PCD). The micro end mill is manufactured by producing a billet made of Superhard material using laser radiation, bonding the billet to a shank of the end mill, and removing material from the billet using laser radiation to produce a cutting tip made of the Superhard material. The laser radiation may comprise a laser beam encased in a water jet or a laser beam with a non-Gaussian intensity profile.

A milling tool for working non-metal materials, in particular wood, engineered wood, and plastic, includes a carrier body, a plurality of cutting elements, which can be inserted into said body on the periphery in a corresponding number of openings extending in the radial direction and can be screwed to the carrier body by way of a bore and which have a plate-shaped and in the cross-section a substantially triangular-shaped design and on a side edge are provided with a blade. The cutting element includes: the region located opposite of the blade is rounded, a groove extending substantially at a right angle to the blade is provided in the bottom, the bore divides the groove preferably into two regions. The opening includes: a web, which extends radially upward from the bottom of the opening serving as a support surface for the cutting element and which corresponds with the groove, a radial threaded bore, which preferably divides the web into two regions, and the cutting element has contact with the opening only with the bottom thereof, a side wall of the groove and part of the region located opposite of the blade.

Embodiments of the invention relate to methods of making articles having portions of polycrystalline diamond bonded to a surface of a substrate and polycrystalline diamond compacts made using the same. In an embodiment, a molding technique is disclosed for forming cutting tools comprising polycrystalline diamond portions bonded to the outer surface of a substrate.
