Seco 00073937 Sdjc Turning Toolholder 1x1 Inch Shank

Product Description

The SECO 00073937 is a right-hand SDJC-style indexable turning toolholder designed for external turning operations on CNC and manual lathes. It features a neutral rake angle of 0 degrees and a 93-degree lead angle, making it well suited for general-purpose turning across a broad range of workpiece materials. The toolholder accepts DCMT 32.52 inserts secured by a screw-clamp holding method, providing consistent insert positioning and reliable clamping force during cuts. The 1 inch by 1 inch square shank fits standard tool post and turret slots common in production turning setups. Weighing 1 pound, it is part of the SECO Multi-Directional Turning (MDT) series.

This toolholder is intended for right-hand cutting direction on turning centers and engine lathes in both job shop and production environments. The universal material compatibility rating covers a wide spectrum of workpiece materials, including steel, stainless steel, cast iron, non-ferrous alloys, high-temperature alloys, and other machinable materials as indicated by the material codes H, K, M, N, P, and S. It is installed by machinists and CNC operators for standard OD turning passes where a neutral rake geometry and screw-clamped DCMT insert are preferred.
