The Irwin Marples 1966893 is a new 14-piece Forstner bit set covering 1/4 in through 2 in in fractional increments, stored in a molded blue plastic carrying case with labeled slots for each bit. Each bit features a high-speed steel construction with a center spur for accurate starting, two outer rim cutters for clean entry, and a flat-bottom cutting geometry suited for drilling blind holes, hinge mortises, overlapping holes, and angled entries in wood, plywood, MDF, and composite materials. The bits use a round shank compatible with standard drill press chucks and handheld drills; the 14 sizes visible in the case tray are 1/4 in, 3/8 in, 1/2 in, 5/8 in, 3/4 in, 7/8 in, 1 in, 1-1/8 in, 1-1/4 in, 1-3/8 in, 1-1/2 in, 1-5/8 in, and 2 in — with one additional size rounding out the 14-piece count. The Marples sub-brand is Irwin's premium woodworking line, and this set is sold new in original retail packaging.
