Seco 00071931 Lh Sclc Indexable Turning Toolholder 5/8 in

Product Description

The SECO 00071931 is a left-hand SCLC-style indexable turning toolholder designed for external turning operations on CNC and manual lathes. It features a neutral rake angle of 0 degrees and a -5 degree lead angle, providing stable, predictable cutting geometry across a wide range of workpiece materials. The 5/8 inch by 5/8 inch shank offers a compact, rigid profile suited for standard tool post and turret mounting. Screw-lock insert clamping holds CC..32.5. series inserts securely under cutting loads. This toolholder is installed and serviced by machinists and CNC tool-setup technicians in production and job-shop environments.

The 00071931 is applied in turning operations where a left-hand cutting direction is required, such as facing toward the tailstock or back-turning on CNC lathes and manual engine lathes. It accepts CC..32.5. inserts, with full compatibility confirmed for CCMT 32.52 inserts. The universal primary workpiece material rating covers steel, stainless steel, cast iron, non-ferrous metals, high-temperature alloys, and other common turning materials, making this toolholder appropriate for general-purpose production turning across a broad spectrum of part materials.

Installation Notes

This toolholder is installed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before changing inserts or seating the toolholder in the turret or tool post. Use the appropriate torx or hex key as specified by the insert screw to avoid stripping the clamping screw. Verify tool centerline height and overhang before returning the machine to operation.
