Seco 00013222 Mvtn Indexable Turning Toolholder Rh

Product Description

The SECO 00013222 is a right-hand MVTN-style negative rake indexable turning toolholder designed for lathe and turning center applications. It features a 1 x 1 inch shank and an overall length of 6 inches, with a head length of 1.71 inches. The toolholder accepts VN..33. series inserts held in place by a clamp and pin method, ensuring secure insert seating during heavy or interrupted cuts. With a negative rake angle, this holder is suited for materials across a broad hardness range. Licensed machinists and CNC lathe operators are the primary installers of this toolholder.

This toolholder is intended for turning operations on a wide range of workpiece materials, including steel, cast iron, stainless steel, non-ferrous metals, and high-temperature alloys, as indicated by its universal primary workpiece material designation covering material codes H, K, M, N, P, and S. A 27.5-degree lead angle influences chip flow and radial cutting force, making it appropriate for facing, profiling, and longitudinal turning. It is compatible with both manual and CNC lathes that accept a 1 x 1 inch square-shank toolholder in the appropriate tool block or turret position.
