Precision thread chaser holders
Troy, Michigan – Seco Tools recently adapted its line of reliable, accurate thread chaser holders to support Steadyline vibration damping bars and Capto tooling. With special carbide-pin locating systems, patented pocket seat surface patterns, and high-pressure coolant delivery, these holders offer consistent insert positioning, superior rigidity, and effective chip evacuation.
Adapted for tooling with Capto C6, Capto C8, or Steadyline GL50 connections, these holders accommodate multi-tooth chasers or single-tooth inserts that perform external and internal threading operations, providing increased options and added flexibility for push or pull configurations. Previously available in a square shank design, these thread chaser holders produce API and common licensed thread profiles across the full range of OCTG materials.
The combination of chipbreaker geometry and direct coolant delivered through the insert and chipbreaker creates optimal chip formation and increases tool life. Maximum pressures reach 70 bar on the new Steadyline and Capto versions of the thread chaser holders and 200 bar on square shank holders.
Thread chaser holders rely on top and axial clamping forces to maintain a tight insert grip during the threading process. These clamping forces produce long, predictable insert life and lower tooling costs. Together these holders and inserts can reduce the number of passes it takes to continuously produce high-precision full thread profiles.
