Hertel H08703175 Threading Insert 22ER 60 Deg Solid Carbide

Product Description

The HERTEL H08703175 is a laydown threading insert designed for external thread-cutting operations on CNC lathes and manual turning centers. Built from solid carbide with a TiC/TiN multilayer coating, this insert delivers the edge hardness and thermal resistance needed for consistent thread form across a range of workpiece materials. It carries the 22ER insert style designation and cuts a 60-degree partial profile thread with a right-hand orientation. The inscribed circle measures 1/2 inch (0.5000 inch decimal), and the insert thickness is 0.187 inches. Designed for use in the 7 to 5 TPI range (3.50 mm to 5.00 mm pitch), this insert suits machinists and toolroom technicians running production threading cycles or job-shop turning work.

This insert is suited for right-hand external threading applications where a 60-degree thread form is required, covering coarse-pitch ranges from 5 to 7 TPI. The 22ER style fits standard laydown threading toolholders that accept this insert geometry. Typical applications include threading mild steel, alloy steel, and other machinable metals on CNC turning centers or manual engine lathes. The TiC/TiN finish improves wear resistance and extends tool life in moderate to high-speed cutting conditions. This insert is sold individually per package, with a minimum order quantity of 10 pieces per order.

Key Features

• TiC/TiN multilayer coating for improved wear resistance and reduced built-up edge
• 60-degree partial profile thread form for standard V-thread applications
• Right-hand external cutting orientation
• Covers 5 to 7 TPI (3.50 mm to 5.00 mm pitch) range
• 22ER insert style fits standard laydown threading toolholders

Compatibility

Designed as an OEM-style replacement threading insert for standard laydown toolholders accepting the 22ER insert style with a 60-degree thread form geometry.

Installation Notes

Threading inserts of this type are installed and indexed by qualified machinists or CNC toolroom technicians. Power down and lock out the machine spindle before seating or replacing any insert. Verify toolholder pocket cleanliness and confirm correct insert orientation before clamping. Follow the toolholder manufacturer torque guidance for the clamping screw to avoid insert fracture or poor seating.
