Thread standard: Metric, ISO DIN 13 Type: Combined machine tap (core hole drilling and thread tapping) Application: Combined (core hole drilling and thread tapping) Material of product: HSSE Surface treatment: no For materials: Materials of medium mechanical strength (alloyed and non-alloyed steels up to 600 N/mm², Malleable cast iron, Graphite cast iron, Copper, Brass, Aluminium, Aluminium-magnesium alloys, Zink alloys, Red bronze, Electron metall, Pressure-cast zink) Tensile strength up to: 600 N/mm2 Standard: DIN 357 Tolerance: ISO2/6H Combined machine taps enables the user to produce the tapping drill hole and the through thread in one operation without any tool changing. The tool incorporates a twist drill before the thread-tapping part. It is possible with this tool to produce through threads up to a maximum threaded depth of 2 x D. It is sensible to use this tool on machines possesing an RPM switchover facility for drilling and tapping.
