Seco 00071948 Sdjc Indexable Turning Toolholder 5/8 Shank

Product Description

The SECO 00071948 is a right-hand SDJC-style indexable turning toolholder designed for external turning operations on CNC lathes and manual turning centers. It features a neutral rake angle of 0 degrees and accepts DC..32.5. series inserts, specifically DCMT 32.52 geometry, secured by a screw-lock clamping method for rigid, repeatable insert positioning. The steel shank measures 0.625 inches wide by 0.625 inches tall with an overall length of 4 inches. This toolholder is intended for use by machinists and toolroom professionals working across a broad range of workpiece materials.

This toolholder is suited for universal material applications including steel, stainless steel, cast iron, non-ferrous metals, high-temperature alloys, and titanium, corresponding to ISO material codes P, M, K, N, S, and H. The screw-lock insert retention system is well suited to medium and finishing turning passes where insert indexing speed and consistency are priorities. The 3-degree lead angle geometry and neutral rake contribute to stable chip formation across these material groups. Typical installations occur in production turning environments and job shops running external diameter operations.

Compatibility

Compatible with DC..32.5. series inserts, specifically DCMT 32.52 geometry, with a 3/8 inch inscribed circle. Designed for use in standard external turning applications across universal workpiece material classifications.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Before mounting or indexing inserts, ensure the machine spindle is fully stopped and locked out per facility lockout/tagout procedures. Seat the toolholder squarely in the tool turret or toolpost and torque the clamping fasteners according to the machine manufacturer's specifications. Inspect the insert pocket and seating surfaces for chips or contamination before each insert change to maintain accurate tool height and cutting geometry.
