In this paper, we report the preparation of artificially patterned millimetre-sized holes in YBa2Cu3Ox (Y123) bulk superconductors. Drilled sintered Y123 pellets have been successfully melt textured and single domain monoliths of 16 mm diameter were obtained. Texture was evidenced by XRD pole figure measurements. Flux mapping was used to verify the homogeneity of the samples and to investigate the field trapping capacity. The trapped magnetic field measured with Hall sensor at 77K is comparable to the hole free parent sample, which has the same thermal history.
