Seco Tools has recently increased its range of reliable and accurate Thread-Chaser Holders to accommodate Steadyline® vibration damping bars and Capto tooling.
By using special carbide-pin locating systems, patented pocket seat surface patterns and high-pressure coolant delivery, these holders ensure precise and consistent insert positioning, high rigidity and effective chip evacuation.
Adapted for tooling with Capto C6, Capto C8 or Steadyline GL50 connections, the new holders can accommodate a wide range of multi-tooth chasers or single-tooth inserts for external and internal threading operations.
Previously available in a square shank design, Seco’s thread-chaser holders can produce API (American Petroleum Industry) and commonly licensed thread profiles across the full range of OCTG (Oil Country Tubular Goods) materials.
The combination of a chip-breaker geometry and direct coolant, delivered through the insert and chip-beaker, optimises chip formation and helps increase tool life.
Maximum pressures reach 70bar on the new Steadyline and Capto versions of the Thread-Chaser Holders, and 200bar 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 result in long, predictable insert life and lower tooling costs.
Together these holders and inserts can reduce the number of passes required to consistently produce high-precision complete thread profiles.
