The Miller Dowel is a stepped, solid-wood structural fastener that forms joints from the outside in. And unlike other methods of wood joinery, our dowels require minimal tools and can be installed exactly where they are needed in any woodworking project – from the outside in.

Design Features of Miller Dowels
The key to the Miller Dowel is its unique patented stepped design which has several benefits. 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 piece to form a secure joint. The sections of the Miller Dowel are not tapered which means that the glue surface remains intact through the entire length as the dowel engages with the wood.

There are three sizes of Miller Dowels
• The 1X for attaching wood pieces up to 1 1/8” thick
• The 2X for wood pieces up to 1 5/8” thick
• The Mini-X for joining 1/2” stock (maximum 3/4”)


Also available is a 1XSR Dowel and companion Dual Bore Drill Bits that have been designed specifically for use in commercial cabinet and furniture production. For more detailed information on any of these Miller Dowels please click on the product name above. Miller Dowels are stepped to achieve three or more separate, parallel diameters. For strength, between each of these is a radial ledge of 45º. The dowels are turned to a furniture-grade tolerance of +/-.008”, and they are kiln dried to a price moisture content of 7% to 9%.

TruFit® Drill Bits
Miller Dowel’s TruFit® Drill Bits, which are stepped to match a correspondingly-sized Miller Dowel, are made from industrial-quality high speed steel for longer cutting life. They are designed with an aggressive helix and polished flutes for efficient chip removal. Three positive locking flats are ground on the shank to prevent spin-out, and a split point prevents “walking” along the grain. TruFit® Drill Bits form precise pilot holes that provide a perfect fit for the parts to be joined.

Dowel Species
Miller Dowels are available in 10 species. For Interior Projects the dowels are available in Red Oak, Black Walnut, Birch and Cherry. For Exterior or Interior Projects you can choose from dowels made from Ipe, Purple Heart, Teak, Mahogany, White Oak and Black Locust.
