Hertel H08700056 Threading Toolholder 1x1 Inch

Product Description

The HERTEL H08700056 is an external, right-hand indexable threading toolholder designed for precision thread-cutting operations on CNC lathes and turning centers. Built in the HSER series, it accepts 16ER inserts secured by a screw-clamp holding method, providing repeatable insert positioning and rigid clamping during threading passes. The 1 x 1 inch square shank measures 6 inches in overall length, giving machinists a solid, consistent interface with the turret or toolpost. At 1.72 pounds, the holder offers a balanced weight for standard lathe tooling setups. This toolholder is suited for shops running external threading operations on steel, cast iron, aluminum, and similar workpiece materials.

The H08700056 is used in external threading applications on manual lathes, CNC turning centers, and turret lathes requiring a right-hand cutting approach. The HSER-1000-6-16 style designation identifies it as a straight-shank holder compatible with common square-shank tool blocks and quick-change toolpost systems. It is appropriate for job shops, production machining environments, and maintenance shops performing thread repair or new thread generation on external diameters. The screw-clamp insert retention method makes it straightforward to index or replace inserts at the machine without special tooling.

Key Features

Compatibility

Designed for use with 16ER indexable threading inserts. The HSER-1000-6-16 style fits standard 1 x 1 inch square-shank tool blocks and quick-change toolpost systems on lathes and CNC turning centers.

Installation Notes

Installation is performed by a machinist or toolroom technician. Secure the shank fully in the toolpost or turret block, ensuring the shank seats flat and square before tightening clamping bolts. Power down the machine and engage the spindle lock before indexing or replacing the 16ER insert. Verify tool offset and thread pitch settings in the control prior to making the first threading pass.
