    Abstract: FIG. 1 is a front, right perspective view of a cutting tool, according to a new design;
    FIG. 2 is a top plan view thereof;
    FIG. 3 is a front elevational view thereof;
    FIG. 4 is a back elevational view thereof;
    FIG. 5 is a right elevational view thereof;
    FIG. 6 is a left elevational view thereof; and,
    FIG. 7 is front elevational view in cross-section of the cutting tool shown in FIG. 1 taken along line 7-7 in FIG. 2.
    The broken lines on the cutting tool in FIGS. 1 through 7 depict portions of the cutting tool that form no part of the claimed design.
    The appearance of any portion of the cutting tool between the break lines shown in FIGS. 1 and 3 through 7 forms no part of the claimed design.
    The underside of the cutting tool (i.e., the side of the cutting tools opposite the side shown in FIG. 2) does not form part of the claim design.

    Abstract: Embodiments relate to polycrystalline diamond compacts (“PDCs”) including a polycrystalline diamond (“PCD”) table having a diamond grain size distribution selected for improving performance and/or leachability. In an embodiment, a PDC includes a PCD table bonded to a substrate. The PCD table includes a plurality of diamond grains exhibiting diamond-to-diamond bonding therebetween. The plurality of diamond grains includes a first amount being about 5 weight % to about 65 weight % of the plurality of diamond grains and a second amount being about 18 weight % to about 95 weight % of the plurality of diamond grains. The first amount exhibits a first average grain size of about 0.5 μm to about 30 μm. The second amount exhibits a second average grain size that is greater than the first average grain size and is about 10 μm to about 65 μm. Other embodiments are directed to methods of forming PDCs, and various applications for such PDCs in rotary drill bits, bearing apparatuses, and wire-drawing dies.
