STAINLESS STEELS

WORKING WITH STAINLESS STEELS DC SWISS Z-INOX THREAD CUTTING POOR THERMAL CONDUCTIVITY, THEREFORE • Overheating of the cutting edge • Material-Gluing with tool (Cold welding) LONG SWARFS, THEREFORE • Tricky chip evacuation in deep blind holes • Risk of swarf nest around tap shank HIGH MATERIAL TOUGHNESS, THEREFORE • Difficult to machine • Limited tool lifetime COLD WELDINGS SWARF NESTS DISSATISFIED CUSTOMER PROPERTIES The tap is made from HSSE-PM and is available with or without internal lubrication. The flutes are helical R 45, for tapping blind holes up to 3 x D1, in Stainless and alloy...
