Seco 00049604 Rh Mvtn Indexable Turning Toolholder

Product Description

The SECO 00049604 is a right-hand MVTN-style indexable turning toolholder engineered for external turning operations on CNC and manual lathes. Configured with a negative 4-degree rake angle, this toolholder seats VNMG 332 inserts and holds them in place with a clamp-style clamping method. The square shank measures 0.75 inches wide by 0.75 inches tall with an overall length of 4.5 inches, making it a common fit for standard lathe tool blocks and quick-change toolpost systems. Cutting direction is right hand and coolant-through is not supported. This toolholder is intended for installation and setup by machinists and CNC turning professionals working across a wide range of workpiece materials.

This toolholder is rated for universal primary workpiece material compatibility, covering material codes H, K, M, N, P, and S. That range includes steel, stainless steel, cast iron, non-ferrous metals, high-temperature alloys, and non-metallic materials. It fits into the SECO Multi-Directional Turning series and is suited for general external turning applications in production, job shop, and maintenance machining environments where consistent insert indexing and reliable clamping are priorities.
