Abstract
579,528. Drills and cutters. FAIREY AVIATION CO., Ltd., and VINES, A. May 17, 1944, No. 9456. [Class 83 (iii)] A tool for producing undercut holes, such as those required in riveting, as described in Specification 572,082, [Group XXV], comprises a shank e slotted to receive a cutter a pivoted on a cross-pin d and having a V cutting- end b and a side cutting- edge c. A projection k engages the work to tilt the cutter as limited by a projection j engaging a stop screw m. A spring g biasses the cutter to the central position.
