RCKT: 90° Rhombic Indexable Turning Insert with positive rake angle. Common sizes include RCKT0804 and RCKT1204, compatible with external turning and facing toolholders. Featuring a sharp cutting edge, smooth chip evacuation, and high positioning accuracy, this insert is primarily designed for semi-finishing and finishing operations on steel and stainless steel workpieces. It is well-suited for machining complex contours; however, due to its moderate edge strength, it is not recommended for heavy-duty or interrupted cutting applications.
RDKT: 55° Rhombic Indexable Turning Insert with positive rake angle. Common sizes include RDKT0702 and RDKT11T3, compatible with profiling toolholders. Characterized by a small nose angle and exceptional profiling capabilities, it delivers light cutting action with minimal vibration. Suitable for materials such as steel, copper, and aluminum, it excels at the precision turning of arcs and tapered surfaces. However, due to its low impact resistance, it is not suitable for roughing operations.
RDKW: 55° Rhombic Negative-Rake Turning Insert. Lacking a positive rake angle, it features a double-sided design for dual-use efficiency. The common size is RDKW1504, compatible with general-purpose turning toolholders. With a robust body construction, it offers high resistance to chipping and impact, making it suitable for both roughing and semi-finishing operations. It is compatible with carbon steel and cast iron workpieces; however, it generates slightly higher cutting forces, and the surface finish achieved during finishing passes is generally inferior to that produced by positive-rake inserts.
RPMW: Round Indexable Milling Insert. Featuring a double-sided, multi-edge design, common sizes include RPMW0803 and RPMW1003, compatible with face milling and profiling cutters. Lacking a distinct nose angle, it possesses exceptional impact resistance, making it ideal for interrupted cutting and surface profiling applications. Compatible with a wide range of materials—including steel, cast iron, and stainless steel—it offers high versatility; however, it is incapable of machining sharp corners or narrow slots.
