Seco 00013198 Mvln Left Hand Indexable Turning Toolholder

Product Description

The SECO 00013198 is a left-hand MVLN-style indexable turning toolholder designed for external turning operations on CNC lathes and manual turning centers. Built on a 1 inch by 1 inch square steel shank with an overall length of 6 inches, this toolholder uses a clamp-and-pin Multiple Lock holding method to secure VN..43. series inserts with a 1/2 inch inscribed circle. The negative rake geometry and -4 degree rake angle deliver strong cutting edges suited for interrupted cuts and harder workpiece materials. A licensed machinist or CNC setup technician installs and qualifies this holder as part of a tooling package.

This toolholder is suited for universal workpiece material applications spanning ferrous, non-ferrous, stainless, heat-resistant superalloys, and cast materials, reflected in its material code coverage of H, K, M, N, P, and S. The left-hand cutting direction makes it the correct choice for back-turning operations or machines with reversed spindle rotation. The 1.5 inch head length and 1.75 inch back-of-bar to cutting edge dimension support standard MVLN toolholder block setups commonly found in production and job-shop turning environments.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. The machine spindle must be fully stopped and all axis motion disabled before mounting or removing the toolholder from the turret or tool block. Use calibrated torque tooling per the machine and toolholder manufacturer guidelines when securing clamp screws, and verify insert seating visually before running. Confirm cutting direction matches spindle rotation before first cut.
