1 EN--10 STAINLESS STEELS Threading up to 3xD 1 Works with Emulsion h6 Tap shank

2 THE CHALLENGE WORKING WITH STAINLESS STEELS POOR THERMAL CONDUCTIVITY, THEREFORE! LONG SWARFS,! THEREFORE Overheating of the cutting edge Material-Gluing with tool (Cold welding) Tricky chip evacuation in deep blind holes Risk of swarf nest around tap shank HIGH MATERIAL TOUGHNESS,! THEREFORE Difficult to machine Limited tool lifetime THE CONSEQUENCES COLD WELDINGS SWARF NESTS DISSATISFIED CUSTOMER

3 THE SOLUTION DC SWISS Z-INOX THREAD CUTTING Z INOX PROPERTIES The tap is made from HSSE- and is available with or without internal lubrication. The flutes are helical R 45, for tapping blind holes up to 3 x D 1, in Stainless and alloy steels with high elongation and tensile strength up to N/mm. SUITABLE FOR SOLUBLE WATER The surface coating provides protection against wear and cold welding. A high slip coefficient facilitates chip removal and reduces torque. PROCESS SAFETY UP TO 3 X D 1 The cutting geometry and shape of the R45 flutes generate compact, regular chips, ensuring process safety. IT S YOUR CHOICE The cutting geometry is suitable for classical tapping with a compensating spindle as well as for rigid tapping (h6 shank for shrinking). THREADING TECHNOLOGY 1
