Hertel 1000089 Ctgp Indexable Turning Toolholder 3/4 in

Product Description

The HERTEL 1000089 is a right-hand CTGP-style indexable turning toolholder designed for external turning operations on CNC lathes and manual turning centers. Built from steel with a 0.75 inch square shank and an overall length of 4.5 inches, this clamp-type holder accepts TP.. 322 series inserts with a 3/8 inch inscribed circle. The positive rake angle of 0 degrees promotes stable cutting geometry suited for a range of workpiece materials. Weighing 0.84 pounds, it is a compact, rigid solution for machinists and toolroom technicians running indexable turning setups.

This toolholder is intended for use in production turning and job-shop environments where repeatability and quick insert indexing are required. The CTGP clamp-type design secures the insert mechanically without the need for a top clamp that interferes with chip flow. The right-hand orientation is suitable for standard front-cutting, left-to-right feed operations on a lathe. It is not configured for coolant-through delivery, making it appropriate for flood-coolant or dry-cutting applications where internal coolant is not required.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Before mounting or indexing inserts, ensure the lathe or turning center is powered down and all axes are at rest. Clamp the shank securely in the tool post or turret to the full clamping depth to prevent deflection under cutting loads. Handle indexable inserts with care as cutting edges are sharp; use appropriate personal protective equipment during insert changes.
