Abstract
393,391. Milling- cutters and drills. O. K. TOOL CO., Inc., 233, Broadway, New York, U.S.A. March 30, 1932, No. 9143. Convention date, Aug. 12, 1931. [Class 83 (iii).] An inserted-blade boring or like rotary cutter, shown particularly adapted as an annular cutter, comprises a body 1 having a central bore 2 with which one or more radial slots 7 communicate. Blades 6, having end and side cutting edges 12, are adjustable along the inclined bases 8 of the slots by means of a screwed ring and lock nut 22, 23 and a pressure ring 18 having an inclined face 19 engaging the ends of the blades. Serrations 11 on the rear faces of the blades and forward faces of the slots are arranged parallel to the bases 8 and major adjustments of diameter may be effected in the cutter by engaging the blades with different serrations on the body. Locking of the blades is effected by screws 17 screwing axially into the end face of the body and having conical heads 17a which open out axial slots 14 located near the forward faces 6a of the blades and extending to the axial bore 2.
