Abstract
608,919. Reamers. NEWBY, J. T. March 2, 1946, No. 6578. [Class 83 (iii)] The peripheral faces E of the blades of a reamer have a spiral form, the radial relief at any. point on a face being directly proportional to its angular distance from the cutting edge Band equal to between one-tenth and two-fifteenths of the circumferential blade thickness at the rear edge F of the blade. A ring of angularly spaced arcuate niches O formed in the non-fluted portion of the body each have a flat face O substantially coplanar with the front face G of the adjacent blade to cooperate with a spring finger to facilitate sharpening. The cutting edges of the blades may be formed as hard metal inserts.
