14 pieces Consisting of precision twist drills and green ring through hole screw taps for processing alloyed and high-alloyed steels (stainless steels), as well as rust-resistant and acid-resistant steels. Also suitable for processing conventional steel materials up to a strength of 850 N/mm².
Premium combination screw tap for precise drilling, thread cutting and countersinking/deburring in just one operation, now also for thicker workpieces with a material thickness of up to 2xD and for almost all materials, such as conventional steels, stainless steels (e.g. V2A, V4A), titanium, heat-resistant and high-strength steels of up to 1200 N/mm² strength and casting materials. Also suitable for non-ferrous metals, such as aluminium, aluminium alloys, bronze and plastics.
