Hertel H08700015 Indexable Threading Toolholder

Product Description

The HERTEL H08700015 is an external, right-hand indexable threading toolholder designed for screw-thread turning operations on lathes and turning centers. Built to the HSER series style, it accepts 11ER threading inserts secured by a screw-clamp holding method for reliable insert retention during cutting. The shank measures 0.375 inches wide by 0.375 inches tall with a 4-inch overall length, making it a compact, rigid option for external threading work. Licensed machinists and tool-and-die technicians working with CNC or manual lathes install this holder as a standard component in threading setups requiring precise insert indexing.

This toolholder is suited for external threading on ferrous and non-ferrous materials in production and job-shop turning environments. Its HSER-0375-4-11 style designation makes it straightforward to cross-reference within standardized tooling systems. The 0.375-inch square shank fits correspondingly sized tool blocks and quick-change toolpost holders commonly found on small to mid-size lathes. No coolant-through capability is included, so flood or mist coolant must be directed externally when coolant is required.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the lathe spindle before mounting or removing the toolholder from the tool block. Seat the shank fully in the tool block and torque the clamping screws evenly to secure the holder before inserting or indexing the threading insert. Verify tool height alignment to spindle centerline before beginning any threading pass.
