Hertel 8852046 Ceramic Turning Insert Wnga 80 Trigon

Product Description

The HERTEL 8852046 is an uncoated ceramic turning insert in the WNGA style, designed for precision metal-cutting operations on CNC and manual lathes. This insert features an 80-degree trigon (W) shape with a negative rake angle and neutral hand orientation, making it suitable for general turning applications where consistent edge geometry is required. Key dimensions include a 0.5-inch inscribed circle, a 0.314-inch insert length, and a 0.0312-inch (1/32 inch) corner radius. The ceramic substrate suits high-speed, dry, or semi-dry cutting of hard or abrasive workpiece materials. Installation and selection are typically handled by machinists and toolroom technicians.

This insert is intended for turning applications where ceramic tooling is selected over carbide for its hardness and heat resistance at elevated cutting speeds. The neutral hand orientation allows use in a variety of right- or left-hand compatible toolholders. The WNGA style with a clamp and pin holding method fits standard WNGA-compatible toolholders. The 80-degree included angle provides a moderately strong cutting edge suitable for general and finishing turning passes on suitable materials.

Installation Notes

This insert is installed and indexed by qualified machinists or toolroom technicians. Shut down spindle power and confirm the machine is in a safe, locked-out state before changing inserts. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer when seating the insert. Inspect the toolholder pocket and locating pin for wear or debris before seating a new insert to ensure proper edge presentation.
