Abstract

836,034. Drills. ALBICO (PRECISION ENGINEERING) Ltd. Sept. 13, 1957 [Sept. 19, 1956], No. 28568/56. Class 83 (3). A masonry or like drill comprises a helical member, such as a coil-spring 4, for clearing dust, at least one end 5 of the spring being inturned to locate in a hole 6 in the drill-shank 3. The rear end 7 of the spring may be left free, or be a tight fit about the shank; alternatively, it may be brazed or welded to the shank. The external diameter of the spring may be equal to that of the drill-head 2 or its inserted tip 1 of tungsten-carbide, and the hole 6 may pass through the shank. Specification 736,423 is referred to.
