Hertel 8852047 Ceramic Turning Insert Wnga Trigon Tin

Product Description

The HERTEL 8852047 is a ceramic turning insert designed for precision metal cutting operations on CNC and manual lathes. Carrying the WNGA432T00625AAHP610CA style designation, this trigon-shaped insert features a TiN (titanium nitride) PVD coating applied over a ceramic substrate, enhancing wear resistance and surface finish at high cutting speeds. The neutral hand orientation makes it compatible with a wide range of toolholders and turning applications. With a 0.5-inch inscribed circle, a 0.3140-inch insert length, and a 1/32-inch corner radius, it is sized for moderate to heavy turning passes where ceramic grade HP610CA performance is required.

This insert is suited for high-speed finishing and semi-finishing of hardened steels, cast irons, and similar difficult-to-machine materials where conventional carbide inserts reach thermal limits. The negative rake geometry and zero-degree clearance angle (clearance code N, tolerance code G) are standard for rigid, stable toolholder setups. It is sold individually per package with a minimum order quantity of 10 units, making it appropriate for shop-stock replenishment or production line tooling programs. Machinists and CNC operators in job shops, aerospace, and industrial manufacturing facilities are the primary installers.

Key Features

• Ceramic insert material with TiN PVD coating for high-temperature wear resistance
• WNGA insert style with trigon (W) shape and 80-degree included angle
• Neutral hand orientation compatible with standard WNGA toolholders
• 1/32-inch corner radius for controlled surface finish and edge strength
• Clamp and pin holding method for secure seating in compatible toolholders
• Negative rake geometry for stable, chatter-resistant cutting in rigid setups

Compatibility

Designed as an OEM-style replacement and stock insert for toolholders accepting WNGA-style trigon turning inserts with a 0.5-inch inscribed circle and clamp-and-pin holding method.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torque wrench and insert screw specified by the toolholder manufacturer when securing the clamp. Inspect the toolholder seat and clamp for wear or debris before seating a new insert, as contamination can affect insert stability and cutting accuracy.
