Seco 00013214 Lh Mvtn Indexable Turning Toolholder

Product Description

The SECO 00013214 is a left-hand MVTN-style negative rake indexable turning toolholder designed for use on manual and CNC turning equipment. It features a 1 x 1 inch shank cross-section and a 6 inch overall length. The toolholder uses a clamp-and-pin insert holding method and accepts VN..33. series inserts with a 3/8 inch inscribed circle. A negative rake angle supports aggressive material removal across a broad range of workpiece materials. Licensed machinists and CNC operators typically specify this holder for external turning operations where tool rigidity and repeatable insert indexing are priorities.

This toolholder is suited for external turning applications in both production and job-shop environments. Its universal primary workpiece material rating covers ferrous metals, non-ferrous metals, stainless alloys, superalloys, and cast materials, corresponding to ISO material groups H, K, M, N, P, and S. The 27.5-degree lead angle and 1.25 inch back-of-bar to cutting edge dimension position the insert for standard facing and turning passes. It is a single-application, non-coolant-through holder in the Multiple Lock series.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholder torque and clamping guidelines. Ensure the machine spindle is fully stopped and the machine is in a safe, locked-out state before changing inserts or mounting the toolholder. Verify insert seating and clamp engagement before taking any cuts. Confirm shank dimension compatibility with the tool turret or toolpost before mounting.
