Seco 00057794 Rh Ciir Indexable Turning Toolholder

Product Description

The SECO 00057794 is a right-hand CIIR-style indexable turning toolholder engineered for cut-off and grooving operations on CNC and manual lathes. Part of the SECO Multi-Directional Turning (MDT) series, it accepts LC..1603.. family inserts secured by a clamp-style holding method. The shank measures 0.5 x 0.5 inches with an overall length of 6 inches, keeping it compatible with standard toolpost and turret setups common in production and job-shop turning environments. The 90-degree lead angle and right-hand cutting direction make this a straightforward drop-in for conventional right-hand turning stations.

This toolholder is rated for universal workpiece materials, covering material codes H, K, M, N, P, and S, which span hardened materials, cast iron, stainless, non-ferrous, steel, and superalloys. It is suited for both light-production and high-mix turning environments where the same holder may be used across multiple material types. The multi-use designation means a single holder can be repositioned for a range of cut-off and grooving applications without dedicated tooling per job. Machinists and CNC setup technicians working in general machining, aerospace component work, or production turning will find this holder applicable to a wide spectrum of part programs.

Key Features

• CIIR toolholder style with 90-degree lead angle for straight cut-off and grooving
• Accepts LC..1603.. inserts including LCGN, LCMF, and LCMR grades for broad insert selection
• 0.5 x 0.5 inch steel shank fits standard lathe toolposts and turret stations
• Insert width capacity of 0.125 inches (3.00 mm) with a maximum depth of cut of 0.43 inches
• Multi-use tool designation supports repositioning across varied cut-off and grooving applications
• No coolant-through requirement simplifies setup and reduces tooling system complexity

Compatibility

Compatible with LC..1603.. series inserts, including LCGN, LCMF, and LCMR insert styles. Insert holding is clamp-type. Designed as an OEM-style replacement or direct application toolholder for right-hand turning stations requiring a 0.5 x 0.5 inch shank and LC1603 insert compatibility.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before changing toolholders or inserts. Secure the shank firmly in the toolpost or turret block to the equipment manufacturer's specified clamping torque using calibrated tooling hardware. Inspect the insert seat and clamp components for chips or debris before seating a new insert.
