Hertel 1000029 Lh Sclc Indexable Turning Toolholder

Product Description

The HERTEL 1000029 is a left-hand SCLC-style indexable turning toolholder designed for use on CNC and manual lathes in metal cutting operations. It features a neutral rake geometry and accepts CC..32.5. series inserts, secured with a screw-clamp holding method for repeatable positioning. The shank measures 0.75 inches wide by 0.75 inches tall, with an overall length of 4.5 inches. The head length is 0.62 inches and the back-of-bar to cutting edge distance is 1.0 inch. The toolholder body is constructed from steel for rigidity under interrupted and continuous turning loads. This holder is installed and serviced by machinists, CNC programmers, and toolroom technicians.

The HERTEL 1000029 is suited for external turning, facing, and profiling applications on ferrous and non-ferrous workpieces. Its left-hand orientation makes it appropriate for operations requiring right-to-left tool travel or for setups on the rear turret of a CNC lathe. The 5-degree lead angle promotes controlled chip flow and surface finish consistency. Coolant-through is not supported on this holder, making it appropriate for standard flood or mist coolant delivery at the tool face.

Installation Notes

Installation is performed by qualified machinists or CNC toolroom technicians. Ensure the lathe or turning center is fully powered down and the spindle is locked before changing toolholders or inserts. Torque the insert clamping screw to the insert manufacturer specification using the correct Torx or hex key — do not overtighten. Verify tool centerline height and offset values after mounting before resuming cutting operations.
