Seco 00061866 Indexable Grooving Toolholder Right Hand Mdt

Product Description

The SECO 00061866 is a right-hand indexable grooving toolholder designed for external grooving operations in the Multi-Directional Turning (MDT) series. Built from steel, it accepts LC..1304.. inserts secured by a clamp-style holding method, delivering rigid, repeatable cutting performance. The toolholder features through-coolant capability to manage heat and chip evacuation at the cutting zone. With an overall length of 8 inches and a maximum depth of cut of 0.79 inches, it is suited for precision grooving on production lathes and CNC turning centers. A minimum groove width of 0.157 inches allows for tight-tolerance grooving work in cast iron and similar materials.

This toolholder is intended for use on CNC turning centers and manual lathes in production and job-shop environments. Its A..-CGHR style designation places it in a class commonly used for external right-hand grooving applications. The primary workpiece material designation is cast iron (K material code), making it a direct fit for gray iron, ductile iron, and similar ferrous castings. The shank measures 0.711 inches wide by 0.671 inches tall with a shank length of 5.99 inches, fitting standard SECO MDT-compatible block systems. Machinists, CNC operators, and toolroom technicians are the typical end users for this toolholder style.
