From the Manufacturer
Forstner bits are designed to drill flat bottom or through holes cleanly in end grain, thin stock, veneers and regular stock. They enlarge existing holes with ease and can bore any arc of a circle. These bits will not move off center through unusual grain or knots. Great for mounting mini-quartz clock movements, cup hinges, and door locks. Sizes 1/4-to-7/8-inch bits are supplied with solid rims. The saw teeth design for larger diameter bits (1-inch and larger) stop burning and cut faster without losing the advantages of Forstner bit action. Includes these high quality steel bits: 1/4, 3/8, 1/2, 5/8, 3/4, 7/8, 1, 1-1/8, 1-1/4, 1-3/8, 1-1/2, 1-5/8, 1-3/4, 1-7/8, 2, 2-1/8. Shank size is 3/8 and overall length is 3-1/2 for sizes 1/4 through 2-1/8-inch.
