Hertel 1000043 Stgc Indexable Turning Toolholder 5/8 Shank

Product Description

The HERTEL 1000043 is a right-hand STGC-style indexable turning toolholder designed for use on CNC lathes and manual turning centers. It features a neutral rake angle of 0 degrees and accepts TC..32.5. series inserts secured by a screw-type clamping method. The 5/8 inch by 5/8 inch shank fits standard toolpost and turret configurations commonly found in production and job-shop turning environments. With a 4 inch overall length and a 3/4 inch head length, this toolholder provides a compact, rigid setup for external turning operations. It is installed by machinists and toolroom technicians working with indexable carbide insert tooling.

This toolholder is suited for external turning applications on both ferrous and non-ferrous materials where a neutral rake geometry is preferred. The screw-type insert retention method provides consistent insert positioning and straightforward index changes during production runs. The 3-degree lead angle geometry and STGC pocket style direct cutting forces efficiently for general-purpose turning. No coolant-through capability is present, making it best suited for flood or dry turning setups rather than high-pressure through-tool coolant systems.

Key Features

• Right-hand cutting orientation with neutral rake (0 degrees) for versatile material engagement
• Accepts TC..32.5. inserts (complete compatibility: TC.. 3252) with screw-type clamping for repeatable indexing

• Single-piece holder design with no coolant-through passage, compatible with external flood coolant

Compatibility

Designed for use with TC..32.5. series indexable turning inserts (complete insert compatibility: TC.. 3252). Fits standard 5/8 inch square shank toolpost and turret stations on conventional and CNC lathes. Manufacturer catalog reference: STGCR L103.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. The machine spindle must be stopped and the turret or toolpost locked before mounting or removing this toolholder. Verify shank seating and torque the clamping bolts to the machine or toolpost manufacturer specifications. When indexing or replacing inserts, use the appropriate Torx or hex key driver and follow the insert manufacturer torque guidelines for the screw-clamp seat.
