Seco 00057603 Indexable Turning Toolholder Srdc Rcmt 0803

Product Description

The SECO 00057603 is a neutral-rake indexable turning toolholder in the SRDC style, designed for use on CNC and manual turning centers. It accepts RCMT 0803 inserts secured by a screw-clamp holding method, providing consistent repeatability during external turning operations. The toolholder features a 0.75 inch x 0.75 inch square shank and a 90-degree lead angle, with an overall length of 5 inches. The neutral cutting direction makes it suitable for multi-directional turning applications. This toolholder is installed by machinists and CNC operators working with a broad range of workpiece materials across production and job-shop turning environments.

The 00057603 is part of the SECO Multi-Directional Turning (MDT) series and is rated for universal primary workpiece material compatibility, covering material codes H, K, M, N, P, and S. This spans hardened materials, cast iron, stainless steel, non-ferrous metals, carbon and alloy steels, and high-temperature alloys. It is appropriate for both roughing and finishing passes where a neutral-hand holder is required. The screw-type insert retention method is standard in production turning and allows fast insert indexing without disturbing the setup.
