Abstract

551,148. Pin drills. FILEN, E. M. May 11, 1942, No. 6357. [Class 83 (iii)] Pin drills have adjustable cutters and interchangeable pilots. The body 1 of the drill is integral with the shank 11 and has a transverse slot opening into a cylindrical bore in which cutters 5, 6 are adjustable by a ring 4 having a scroll 11 engaging teeth on the ends of the cutters which are beaded to fit the bore. Spring pressed balls 2 restrain the ring 4 from axial movement in the shank. A headed pin 7 carries a pilot 8 and both pin and pilot are slotted to pass the cutters. All the parts are clamped, after adjustment, by a screw 9. Seven sets of cutters cover a range from 7 to 55 mm. The scroll ring may be replaced by a sliding ring to adjust the cutters by a bevel closing action.
