Abstract
273,134. Coaton, A. A. Oct. 25, 1926. Percussive drills. - A rock-drill bit is formed theoretically by cylinders 2 and 6 intersecting at right angles, which are cut by planes 5 to form a cutting edge 4, plane faces 5 and cylindrical curved sides 11, due clearance away from the reaming edge being thereby provided. Fig. VIII shows a practical drill in which slight wear of the cutting edge will not lessen appreciably the diameter of the hole being bored while part of the edges 8 will exercise a reamering action in the hole. Fig. IX shows a modification with four radial cutting edges 8.
