Bring micro-threading capability to your Citizen, Star or Tornos Swiss-type lathe with the Cutoutil Mini External Threading Tool 6 mm 55° Full Profile. Designed for watch crowns, medical bone screws and micro-connector housings, this tool doubles as a tiny boring cutter when clearance is under 0.4 mm. The 55° insert forms perfect crest and root without secondary passes, eliminating the chatter common to ground HSS taps. Micro-grain carbide combined with high-positive rake reduces cutting force below 0.3 N, letting you hold 0.005 mm concentricity on 0.8 mm threads. TiAlN coating evacuates heat at 25 000 rpm, extending edge life to 1 200+ stainless-steel parts. Every tool is batch-coded and laser-marked for full traceability in ISO 13485 facilities. Upgrade to Cutoutil and turn your micro lathe into a threading powerhouse.
