What is the Miller Dowel?

Imagine a stepped, solid-wood structural fastener that forms tight joints all the way through. Unlike other methods of wood joinery, each of these requires minimal tools and can be installed anywhere they’re needed in any project from the outside, in. The key to its utility is the unique patented stepped design. The first section acts like a clamp that securely holds the first piece to the second. The second section gives the joint shear strength. The remaining sections bond with the anchor pieces to form a secure joint. The sections are not tapered, which means that the glue surface remains intact through the entire length of the dowel engaging with the wood.

Stepped Design

The stepped design of our dowels is designed to achieve three or more separate parallel diameters.

  1. For strength, each one is a radial ledge of 45 degrees.
  2. They are turned to a furniture-grade tolerance of +/- .008″.
  3. Kiln-dried to a moisture content of just 7% to 9%.
Tips:
  • The depth drilled determines the depth of insertion. This not only allows users to countersink, tap flush, or leave raised but also gives woodworkers the option to only use a portion of the dowel.
  • If only two sections of the drill bit are used, then only two sections of the dowel will be inserted. This technique doubles the versatility of the product because it means that each size Miller Dowel is two sizes in one. It is an ideal feature when depth or thickness is restrictive, or for achieving a decorative effect.

Steps:

  1. Using the Miller TruFit stepped bit, drill a pilot hole through the top piece and into the substrate.
  2. Apply glue to the rib section of the dowel.
  3. Insert the dowel so that it drops approximately two-thirds its length, tapping until it is flush or fully seated in the hole
  4. The remaining portion can be trimmed off or sanded until smooth.

Tips:

  • The dowel will self-center and align with the second board even if you have not pre-glued or clamped the components. Tap in the dowel until it’s fully inserted and trim or sand any raised portions.
  • The depth drilled determines the depth of insertion. This not only allows users to countersink, tap flush, or leave raised but also gives woodworkers the option to only use a portion of the dowel. If only two sections of the drill bit are used, then only two sections of the dowel will be inserted. This technique doubles the versatility of the product because it means that each size Miller Dowel is two sizes in one. It is an ideal feature when depth or thickness is restrictive, or for achieving a decorative effect.
