LT Threading
Ensure accurate and high-quality threads with Laydown Triangle (LT) threading tooling. The system is designed with a low profile for fine-pitch internal threading applications. The LT threading systems include boring bars, boring heads, toolholders, and inserts. With a wide selection of 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 Internal Diameter (I.D.) threads. The LT threading toolholders include an insert screw and a top clamp for easy switch outs. This comprehensive system is designed to minimize built-up edge, reduce cutting forces and precisely cut most materials.
