Technical information i 4.2. Groups of Tools by Applications Group of machine taps intended for high performance thread cutting in a wide range of materials, such as steel, stainless steel, cast iron, non-ferrous metals and heat-resistant alloys, and titanium alloys. MASTERTAP The thread cutting may be carried out in modern, highly efficient machining centers with high cutting speeds, on the older types of CNC machines, and on the P M K N S conventional machines with slightly lower processing parameters. Innovative variety of machine tap 800, designed also for processing of stainless steel. The innovative manufacturing technologies may even double durability and 800 processing performance we had so far. All these features make the 800X tap the best choice for small and medium size production series, while still offering favorable price to quality ratio. P M K N 800 For structural, free machining and low alloy steels with the tensile strength of 600 MPa ≤ Rm ≤ 800 Mpa P K N For tool and difficult to process steels with the tensile strength of 800 MPa ≤ FAN-1200 Rm ≤ 1200 MPa, and for heat treated steels up to 38 HRC P 1400-HT For machining hard and abrasive materials such as steel with a tensile strengthfrom 1200 to 1400 MPa and aluminium with high silicon content. P M K N For high alloy steel, stainless and acid resistant steels with a tensile strength of INOX Rm ≤ 1000 MPa P M GG For processing of grey and nodular cast iron K GAL For cast aluminum alloys with the Si content of max. 12% N For materials, which have been hardened. The number next to the symbol indicates HRC the maximum hardness of the material to be processed, in the HRC scale H S-NC For synchronized tapping on CNC machines with the "rigid tapping" function fora wide range of materials with the high cutting speeds P M K N S Ms For brass and short chip bronze 12 N 285
