A Diamond Enhanced Insert (DEI) includes a working layer of a polycrystalline diamond material (PCD). The PCD material includes a first phase that includes a number of particles of a first material. The PCD material also includes a second phase that is adapted as a catalyst. The PCD material has a fracture toughness greater than 12.5 MPa·√m, a flexural strength of greater than 800 MPa, and a diamond frame strength of less than 400 MPa.
