Info v c Product Finder 1.1 General technical information regarding EMUGE threading tools EMUGE threading tools are made exclusively of high-performance high-speed steels according to EMUGE specifications. Our modified tool steels are based on the material alloy group HSSE acc. DIN ISO 11054. As for tools which are designed for a special application, these generally used tool materials do not come up to our requirements. In such cases we use special high-speed steel alloys and carbide materials which are specially selected for the work case in question. A rigorous quality control of these materials forms the basis of our high-quality tools. Research and development work is carried out in a specially equipped laboratory, and serves as an indispensable precondition for the further development of cutting geometries and other parameters necessary for thread production. Extensive tests and trials on CNC machines, conventional drilling and thread cutting machines guarantee the performance and economic efficiency of our tools. 1.2 Dimensions and technical sales conditions The dimensional specifications of our threading tools are adjusted to the currently valid standards, with the exception of special tools made to EMUGE standards. The DIN standards for taps are based on the General Plans of Dimensions for Taps acc. DIN 2184-1 and -2. Please read the notes in this catalog and in the technical introduction carefully. The technical sales conditions for taps acc. DIN 2197 and roll form taps acc. DIN 2175 have been taken into account. The manufacturing tolerances for the thread part are in accordance with DIN EN 22857 and DIN 802. All specifications, illustrations and dimensions are subject to change due to technical progress and possible changes of the standards, and are consequently without obligation. 1.3 Constructional designs of our EMUGE taps Constructional design EMUGE designation Hand taps, short machine taps Rekord Enorm Machine taps with reinforced shank Rekord 1 Enorm 1 Machine taps with reduced shank Rekord 2 Enorm 2 Robust 2X Machine taps with long flutes and long shank LF Machine taps with extra long shank LS
