The Miller Dowel joinery system is an ingenious and simple way to securely join wood parts together. The system uses a stepped drill bit and dowels that produce better, stronger joints with less effort and set up. Simply drill a pilot hole with the patented high-speed steel (HSS) step drill bit, apply glue to the ribs on the dowel and drive the dowel home to pull the joint together. The step dowel design reduces the amount of glue squeezed off as the dowel is driven home creating a stronger adhesive bond. Once the glue dries, the exposed dowel is trimmed and sanded creating a strong and attractive joint. Miller Dowels can create joints in a wide range of woodworking projects. Stepped dowels have shear strength similar to that of screws or nails. Miller Dowels are a suitable alternative to mortise and tenon, loose tenon, traditional blind or through dowel or biscuit joints requiring less set up and specialized machinery.
