Seco 00002850 Lh Cfml Indexable Turning Toolholder

Product Description

The SECO 00002850 is a left-hand CFML-style indexable turning toolholder designed for cut-off and grooving operations on CNC lathes and turning centers. Built with a 3/4 inch by 3/4 inch steel shank and an overall length of 4.5 inches, this toolholder uses a clamp-style insert holding method to secure LC..1603.. series inserts. It is part of the SECO Multi-Directional Turning (MDT) series, which supports versatile cutting applications across a wide range of workpiece materials. Machinists and CNC setup technicians working in production or job-shop environments will find this holder compatible with universal workpiece materials including ferrous, non-ferrous, and exotic alloys.

This toolholder is suited for left-hand cutting direction applications in external turning, grooving, and cut-off operations on manual and CNC turning equipment. The CFML style and 90-degree lead angle make it appropriate for applications requiring a straight shoulder approach. It accepts LC..1603.., LCGN, LCMF, and LCMR insert families, giving the operator flexibility in choosing insert geometry and grade for the specific material and finish requirement. The multi-use tool designation means a single holder can serve across multiple operation types without requiring a dedicated toolholder change.

Compatibility

Compatible insert families include LC..1603.., LCGN, LCMF, and LCMR inserts. The compatible insert size code is LC1603. This toolholder is rated for universal primary workpiece material categories including material codes H, K, M, N, P, and S, covering hardened materials, cast iron, stainless, non-ferrous, steel, and superalloys.

Installation Notes

Installation is performed by qualified machinists or CNC tooling setup technicians. Power down and lock out the machine spindle before seating or changing inserts and before mounting the toolholder in the tool block. Use calibrated torque tools when tightening the clamp screw to manufacturer-specified values found in the SECO insert and toolholder documentation. Verify insert seating and tool offset measurement before running the first part.
