Latest Patents

Bollands holds a patent for a unique invention known as the Drill Shoe. This drill shoe is specifically designed to fit onto a drill pipe with an external diameter (d.sub.e) and an internal diameter (d.sub.i). The invention features an externally stepped cutting surface with multiple steps, where the diameters of the steps increase as they move away from the tip of the shoe. The maximum external diameter (D.sub.e) of the shoe exceeds the external diameter (d.sub.e) of the drill pipe. Additionally, the shoe has an internal, substantially cylindrical inner surface with a diameter (D.sub.i) that is less than the internal diameter (d.sub.i) of the drill pipe. This design makes the shoe suitable for use in a vibratory drill string, particularly for obtaining cores from unconsolidated geological formations such as soil, sand, and gravel.
