Description

The SECO 00057795 is a left-hand CIIL-style indexable turning toolholder designed for external turning, cut-off, and grooving operations on CNC and manual lathes. It features a 0.5 x 0.5 inch square shank and an overall length of 6 inches. The holder uses a clamp-style insert holding method and accepts LC..1603.. series inserts, making it a versatile choice across a wide range of workpiece materials. It is part of the SECO Multi-Directional Turning (MDT) series, built for shops that need flexible tooling solutions with consistent insert indexing.

This toolholder is suited for both production and job-shop turning applications where left-hand cutting direction is required. The 90-degree lead angle and 0.43 inch maximum depth of cut make it effective for grooving and cut-off work on ferrous and non-ferrous materials. Compatible insert grades cover universal workpiece material groups including steel, cast iron, stainless, non-ferrous, and high-temp alloys. Machinists, toolroom technicians, and CNC setup personnel are the primary installers of this toolholder.

Installation Notes

Installation is performed by machinists or CNC setup technicians. Secure the toolholder in the turret or toolpost before indexing or replacing inserts, and verify the machine is powered off and the spindle is fully stopped before any tooling change. Use the correct torque wrench and clamp screw for the LC..1603.. insert pocket to avoid seat damage. Confirm cutting direction and lead angle orientation match the programmed toolpath before running the first part.
