Hertel 1000034 Lh Sdjc Indexable Turning Toolholder

Product Description

The HERTEL 1000034 is a left-hand SDJC-style indexable turning toolholder designed for external turning operations on CNC and manual lathes. It features a neutral rake geometry and accepts DC..32.5. series inserts secured by a screw clamp, providing a rigid, repeatable cutting edge location. The shank measures 0.625 inches wide by 0.625 inches tall with an overall length of 4 inches, making it well suited for standard tool posts and turrets in production and job-shop environments. The body is machined from steel for durability under continuous turning loads. Licensed machinists and CNC operators are the primary installers of this holder.

This toolholder is used in turning centers and engine lathes for longitudinal turning, facing, and profile work where a left-hand cutting direction is required. The SDJC style positions the insert at a 3-degree lead angle, which promotes axial cutting forces and helps reduce vibration on moderate to long overhangs. The screw-type insert holding method keeps the insert pocket accessible for quick indexing during production runs. Typical applications include steel, cast iron, and non-ferrous workpiece materials in both light finishing and medium roughing passes.

Key Features

• Left-hand SDJC holder style with 3-degree lead angle for controlled axial cutting forces

Compatibility

Designed to accept DC..32.5. series indexable inserts with a 0.375-inch inscribed circle, as specified by the manufacturer. Verify insert designation against the complete compatibility listing DC.. 3252 before ordering inserts.

Installation Notes

Installation is performed by qualified machinists or CNC toolroom personnel. Secure the toolholder in the tool post or turret station before powering on the machine and establishing any tool offsets. Torque the insert clamping screw to the insert manufacturer's specification and confirm cutting edge height relative to workpiece centerline before taking a cut. Always index or change inserts with the machine in a full stop condition and the control in an appropriate safe state.
