Threading LAYDOWN TRIANGLE THREADING Explore Laydown Triangle Threading Materials Primary Secondary P M K S N Industries General Automotive EV Oil & Gas Engineering Aerospace & Medical Wind & Solar Defense Applications Laydown Triangle (LT) threading is the system of choice for fine-pitch threads, high-helix/multistart threads and single-point threading in small-diameter bores. With a wide selection of CB-style chip control inserts, you will receive superior chip management for excellent surface finishes and minimal operator intervention. The low profile design enables unrestricted chip flow — ideal for I.D. threads. Variable shim angles enable proper cutting geometry for high-helix angle and reverse helix angle threading, maximizing tool life and improving thread quality. A89 kennametal.com
