Iscar Metals, Inc. (Arlington, TX) has introduced a new 80° rhombic insert for turning applications. The new HELITURN LD (Lay Down) family of tools offers many of the advantages of the original HELITURN TG (Tangential) family of tools. These inserts feature a positive radial, helical cutting edge and positive rake angle for reduced cutting forces and increased metal removal rates. A subsequent finishing operation is often not needed when using these new inserts. The wiper geometry of the insert’s corner produces high surface finish even at high feedrates. These inserts were designed with heavy machining applications in mind and feature a sturdy 88° corner. The inserts can be mounted into a standard Iscar R-Clamp toolholder, but does require a special TCH 4 seat.
