New Seco chaser inserts offer perfect pitches and profiles with single-pass threading capability

Fagersta, December 2014 – Seco’s new Thread Chaser inserts provide the speed, reliability and accuracy needed to meet the demanding requirements of the oil and gas industry and other segments that rely on special purpose threads such as API thread types to ensure superior hydraulic sealing in modern oil and gas components. Seco also offers threading products that are produced under license from leading brands within the oil and gas industry.

The versatile Thread Chaser tool features inserts for both push and pull threading of I.D. features using multi-tooth patterns for fast single- or two-pass threading. The system’s multi-tooth inserts have precise thread patterns that quickly and reliably generate high-accuracy, consistently perfect thread pitches for industry-specific parts and pipe materials in a wide range of hardnesses.

Thread Chaser inserts increase productivity by generating the thread teeth, facing and taper at the same pitch as the thread type. The tools use a special substrate material and feature through-coolant holes and chip formers to direct high-pressure (up to 210 bar) coolant precisely to the cutting edges to optimise chip formation/evacuation and extend insert life. Inserts are available in push or pull and push/pull sets of one, two or three to accommodate various thread machine types.
