The combination of Miller Mini-X Walnut and Miller Mini-X Step Drill Bit provides a fast, durable and decorative joinery process. These products were shipped promptly and their packaging prevented damage in transit. Users must be sure that the drill is perpendicular to the target surface. With these products, especially on thinner woods, a drill and jig should be used to ensure correct angles. Miller Mini-X products work well with 1/2 inch lumber.
