Miller Dowel Company’s TruFit Drill Bits are stepped (not tapered) to create the perfect pilot hole to match a corresponding Miller Dowel. The fit between the Miller Dowel and the TruFit pilot hole results in just the right amount of surface tension to give the dowel its well known ‘instant set time’ when seated.TruFit Drill Bits are made from hardened, high quality industrial grade high-speed steel (HSS) that can withstand high temperatures without compromising performance, or shortening the cutting life of the tool. Our drill bits are computer ground to a tolerance of two thousandths of an inch. They are designed with an aggressive helix and deep polished flutes to evacuate debris and to create efficient cutting angles. TruFit Drill Bits are extremely effective at cutting and removing large amounts of wood material quickly and easily.
