When your job demands a tiny boring cutter that refuses to compromise on rigidity, the Cutoutil 6 mm micro boring bar delivers. Designed specifically for stainless steel mini internal turning, this micro tool combines a sub-micron carbide substrate with an anti-weld TiSiN coating, giving you mirror finishes and predictable tool life on 303, 304, 316L and 17-4 PH. The internal coolant channel flushes chips at 150 bar, eliminating the re-cutting common with small-diameter boring. Whether you run a Citizen, Star or Tsugami Swiss-type, our micro boring bar drops straight into your 8 mm tool-post-no bushing mods required. Upgrade to the tiny boring cutter that machinists trust for aerospace, medical and micro-mold work.
