Product title: MLCS 9235 2-3/8-Inch Diameter Steel Forstner Bit
Product description: MLCS forstner bits are manufactured from high quality steel that is long lasting, precision ground for heavy use and easily resharpened. 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-Inch 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. Shank size is 3/8-Inch and overall length is 3-1/2-Inch for sizes 1/4-Inch through 2-1/8-Inch excluding metric sizes. For sizes 2-1/4-Inch through 4-1/2-Inch shank size is 1/2-Inch and overall length is 6-3/8-Inch. Use large bits in drill press
