Machining and cutting tools including, but not limited to, rotary drill bits, mining tools, milling tools, wood shredders, reamers and wire dies formed with at least one substrate having a layer of polycrystalline diamond disposed thereon. The polycrystalline diamond layer may be generally described as a polycrystalline diamond compact (PDC) or PDC layer. The PDC may be formed by using an intermetallic aluminide catalyst. One example of such catalyst may include nickel aluminide used to form diamond to diamond bonds between adjacent diamond particles.
