Seco 00071939 Left Hand Sdjc Indexable Turning Toolholder

Product Description

The SECO 00071939 is a left-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 screw-lock insert holding method, providing secure clamping and consistent cutting-edge repeatability. The shank measures 0.5 inches wide by 0.5 inches tall with an overall length of 3.5 inches. The toolholder is manufactured from steel and accepts DC..32.5. series inserts with a 3/8-inch inscribed circle. It is suited for universal workpiece materials across a broad range of machining applications and is installed by machinists and toolroom technicians.

This toolholder is used in turning centers and engine lathes requiring left-hand cutting direction. It is suited for facing, profiling, and longitudinal turning on a wide range of workpiece materials including ferrous metals, non-ferrous metals, and high-temperature alloys. The -3 degree lead angle and screw-lock clamping system make it a reliable choice for production turning environments where insert indexing speed and rigidity are priorities. Coolant-through capability is not supported on this holder.

Installation Notes

Install and service by a qualified machinist or toolroom technician. Power down and lock out the machine before changing inserts or repositioning the toolholder in the turret or tool block. Use the appropriate torque wrench and screw driver for the screw-lock clamping screw to avoid overtightening, which can damage the insert seat or clamping screw. Verify insert seating and clamping before resuming cutting operations.
