Seco 00013207 Mvln Indexable Turning Toolholder Rh

Product Description

The SECO 00013207 is a right-hand MVLN-style indexable turning toolholder designed for external turning operations on CNC lathes and manual turning centers. Built to the Multiple Lock series standard, it uses a clamp-and-pin insert holding method to secure VN..43. style inserts with a 1/2-inch inscribed circle. The toolholder features a negative rake angle of -4 degrees, a -5 degree lead angle, and a 1.25-inch by 1.25-inch square shank. At 6 inches overall length, it provides rigid setup geometry suited for general-purpose turning across a wide range of workpiece materials. Licensed machinists and CNC lathe operators install this holder in production and job-shop environments.

This toolholder is intended for turning applications on both production CNC lathes and manual turning centers. Its universal material compatibility rating covers ferrous and non-ferrous metals including steel, cast iron, stainless steel, aluminum, and superalloys, corresponding to ISO material codes H, K, M, N, P, and S. The right-hand cutting direction and negative rake geometry make it well suited for roughing and semi-finishing passes where insert strength and edge security are priorities. It is a single-use-per-setup, non-coolant-through design.
