Hertel 1000123 Mrgn Indexable Turning Toolholder 1x1 Shank

Product Description

The HERTEL 1000123 is a right-hand MRGN-style negative rake indexable turning toolholder designed for precision metal cutting on CNC and manual lathes. Built on a 1 x 1 inch square shank with a 6-inch overall length, it accepts RN..43. series round inserts held by a clamp and screw method. The -5 degree negative rake angle and 15-degree lead angle position the insert for stable, controlled cuts on steel and other ferrous materials. Toolholder body is constructed from steel for rigidity under heavy turning loads. This holder is installed by machinists and CNC operators in production and job-shop turning applications.

The HERTEL 1000123 is suited for external turning operations on manual engine lathes and CNC turning centers. The right-hand orientation means it feeds from right to left along the workpiece. Its 1-inch square shank fits standard tool blocks and turret stations commonly found in general-purpose turning setups. The 1.25-inch back-of-bar to cutting edge dimension and 0.5-inch insert inscribed circle support consistent tool height setup in production environments. No coolant-through capability is present, so external coolant delivery is required when running coolant-assisted cuts.

Installation Notes

Installation is performed by machinists on manual or CNC turning equipment. Power down and lock out the machine spindle before seating or indexing inserts. Secure the shank fully in the turret or tool block to the required clamping depth before taking cuts. Do not exceed the insert manufacturer's recommended depth of cut or feed rate for the selected RN..43. insert grade.
