Abstract

1,082,987. Tapping. ERNST SCHLIEMANN'S EXPORT-CERESIN-FABRIK. Dec. 17, 1964, No. 51382/64. Heading B3N. A method of tapping blind holes comprises first filling the hole with a mass of material of wax-like consistency, consisting of a low-watercontent soda soap with the addition of glycerine or glycol, and then carrying out the tapping operation. The material may be fed into the drilled hole in the form of a cartridge, or it may be used in belts or threads, the threads being cut off flush with the surface of the material. The method can be used for tapping cast iron, wrought iron, steel, copper, brass, bronze, aluminium, ferro-manganese, light alloys, precious metals, plexiglass, and moulded or extruded plastics.
